Standard Lead Acid vs. Lithium-Specific Chargers: What's the Difference?

Lithium-specific chargers are designed to charge LiFePO4 batteries more efficiently, using a charge profile that matches their voltage and discharge characteristics. In contrast, standard lead-acid chargers typically follow a simpler charge profile, often not optimized for the charging needs of lithium batteries. This can result in slower charging times, reduced battery life, or even damage to lithium batteries if a lead-acid charger is used.

Below are the detailed differences.

1. Charging Algorithm

Firstly, these 2 types of batteries have different charging algorithm.

Lead-Acid Battery:

Lead-acid chargers typically operate in three stages:

• Bulk Stage: During this stage, the charger supplies a constant high current to the battery. The voltage rises steadily until it reaches the battery's nominal voltage (around 14.4-14.8V for a 12V system).
• Absorption Stage: Once the battery voltage reaches the target, the charger switches to constant voltage mode. The current is reduced, and the voltage is held steady to fully charge the battery. This stage can take a while, depending on the state of the battery.
• Float Stage: After the battery is fully charged, the charger reduces the voltage to a lower, maintenance level (around 13.2V for a 12V system). This helps maintain the charge without overcharging. This stage is intended to keep the battery topped off when not in use.

Lead-acid batteries are more sensitive to overcharging and require careful management of the charging voltage to prevent damage.

LiFePO4 Lithium Battery:

However, the charging logic for lithium batteries, particularly LiFePO4, is typically CC/CV—which stands for Constant Current / Constant Voltage. Here’s a closer look at how CC/CV charging works for lithium batteries:

A. Constant Current (CC) Stage

In the CC stage, the charger provides a constant current to the battery while the voltage gradually increases. This phase continues until the battery reaches a pre-set maximum voltage (typically 14.4V to 14.6V for a 12V LiFePO4 battery).

• Purpose: This phase rapidly charges the battery up to about 80-90% of its capacity.
• Current Level: Often set to a high, steady current level, but it should be within the safe charging limits of the battery to avoid overheating.

B. Constant Voltage (CV) Stage

Once the battery reaches the target voltage, the charger switches to constant voltage mode, where the voltage is held steady at this set maximum (e.g., 14.4V for a 12V LiFePO4). During this stage, the current gradually decreases as the battery approaches full capacity.

• Purpose: This phase “tops off” the battery, filling the remaining capacity while avoiding over-voltage.
• Current Tapering: The current decreases naturally as the battery approaches full charge, typically tapering down to a very low level (around 1-2% of the rated capacity), which signals the battery is fully charged.

C. Charge Termination

Unlike lead-acid batteries, lithium batteries don’t need a float stage, as they don’t self-discharge as quickly. Charging is considered complete when the current in the CV stage drops to a minimal level.

• No Float Stage: LiFePO4 batteries don’t require float charging; they hold their charge effectively without it.
• Charge Cut-Off: At this point, the Battery Management System (BMS) may stop the charging to prevent overcharging, or the charger will automatically shut off if designed to recognize the fully charged state.

This two-stage CC/CV process is ideal for lithium batteries because it efficiently fills the battery without overcharging. Overcharging can lead to overheating and reduced capacity, so maintaining precise voltage limits in the CV stage is crucial for lithium batteries’ longevity and safety.

2. Voltage Limits

Lead-Acid: Lead-acid batteries typically charge to 14.4V to 14.8V (for a 12V system). If the voltage exceeds this range for prolonged periods, it can damage the battery and cause gassing, which leads to the loss of electrolyte.

Lithium (LiFePO4): Lithium batteries charge to a slightly higher voltage (typically around 14.4V to 14.6V for a 12V system). Exceeding this voltage can damage the battery, reduce its lifespan, or cause thermal runaway in some cases.

3. Temperature Compensation

Lead-Acid: Lead-acid chargers often include temperature compensation to adjust the charging voltage based on the temperature of the battery. Cold temperatures can lower the voltage, while high temperatures can increase it. This helps prevent damage to the battery.

Lithium (LiFePO4): Lithium batteries are less affected by temperature extremes compared to lead-acid, but high temperatures can still damage them. While some lithium chargers have basic temperature compensation, it’s not as critical as it is for lead-acid batteries. Many lithium batteries have built-in Battery Management Systems (BMS) that monitor temperature and prevent charging if the battery is too hot or too cold.

4. Self-Discharge and Maintenance

Lead-Acid: Lead-acid batteries have a higher self-discharge rate, meaning they lose charge more quickly when not in use. They require a float charge to keep them maintained when not in use for long periods.

Lithium (LiFePO4): Lithium batteries have a much lower self-discharge rate, and they do not need constant float charging. They can be stored for long periods without significant loss of charge, which is one of the advantages of using lithium over lead-acid in many applications.

Using the wrong charger (e.g., a lead-acid charger for lithium batteries) can result in battery damage, reduced lifespan, or even dangerous conditions, so it's always essential to match the charger with the battery type for optimal performance and safety.

Why Choosing the Right Charger for Your Lithium Battery Matters

Picking the right charger for your lithium battery isn’t just a technicality—it’s a key decision that affects your battery's performance, safety, and lifespan.

Are you looking to replace your batteries in your RV, Camper or Van? Building a new van? Or considering an upgrade to lithium? Here’s a simple guide to what type of battery you need, how to choose the right size battery bank, and how much solar power you would need to be self sufficient and go fully off grid.

What type of battery do I need for my RV?

RVs, Campers, and Vans have two types of batteries. One is a automotive/starter battery that is used to start the engine. The other is a deep cycle battery, also called a house battery, that is used to power your electronics. Your solar panels, if you have them, re-charge your deep cycle / house batteries but do not directly power your electronics. The house batteries are your power source, the rest of your electrical system either gets power to your batteries (charging) or pulls power out (discharging) to run your fridge, lights, etc.

Most RV and Vanlife electronics will operate with any deep cycle 12-volt marine battery. Most stock RVs come with lead acid batteries because they are cheap, and if you are doing a Van build or an RV build it might be tempting to buy a lead acid battery (also called AGM or SLA) because they are low cost and widely available at any auto parts store. But for the longest run time, most efficient use of solar power, longest lifespan, and greatest reliability and best piece of mind we recommend lithium iron phosphate (LiFePO4) batteries.

Steps to Choose the Right Lithium Battery

1. Calculate Your Power Needs:
   Add up the wattage of all the devices and appliances you plan to power. This will help you determine the required battery capacity (measured in amp-hours).
2. Choose the Right Voltage:
   Most RVs and campers use 12V battery systems, but higher voltage options (e.g., 24V) may be needed for larger setups.
3. Consider Battery Size and Weight:
   Lithium batteries are much lighter and more compact than lead-acid batteries, making them ideal for RVs and vans with limited space.
4. Think About Lifespan and Durability:
   Dakota Lithium batteries are built to last, with a lifespan of up to 2,000 cycles.
5. Pair with Solar Panels:
   Maximize your off-grid capabilities by pairing your lithium battery with Dakota Lithium solar panels.

8 reasons to choose a lithium RV battery

1. Dakota Lithium LiFePO4 batteries will provide double the usable power and run time of lead acid. More power and run time means more time on the road without having to plug in at night. Allows for boondocking or camping off grid with the confidence that your batteries will get your through the night (or with solar panels near indefinitely).
2. Dakota Lithium batteries last 8X longer than AGM or lead acid batteries and will need to be replaced less often. Providing reliability and peace of mind, as well as greater lifetime value. All backed up by a best in class 11 year warranty.
3. Dakota Lithium weighs 60% less than deep cycle lead acid batteries. Less weight means more maneuverability and speed and less wear and tear on your rig. And the batteries are light enough that you can easily install and service them yourself.
4. Dakota’s lithium iron phosphate works down to negative 20 degrees Fahrenheit (-29 Celsius) meaning you can travel in all seasons. In addition, the DL+ 12V 135Ah battery and the DL+ 12V 320Ah batteries have internal heating for charging while camping in freezing temperatures.
5. The self discharge rate of a Dakota Lithium battery is 1/4 that of a lead acid battery, only 1-2% a month. That means if you take a break between adventures your batteries will still have plenty of power the next time you hit the road.
6. Dakota Lithium iron phosphate is optimized for solar energy with 50% more efficiency than a lead acid battery.
7. You need less batteries when you use a Dakota Lithium. Lithium iron phosphate (LiFePO4) has a flat voltage curve. That means that the voltage does not drop as you use the battery. You get all the juice down to the last drop. Historically if you power your house electronics with a deep cycle lead acid battery you would only be able to use half of the capacity of the battery before the voltage is too low to run anything. That’s why your lights dim when your lead batteries are low. With Dakota Lithium you can use all of the power of the battery, meaning that a 100 Ah battery from Dakota Lithium is equal to 200 Ah in lead acid batteries.
8. Dakota Lithium has an 11 year warranty. That means you can install your batteries once, instead of replacing heavy lead acid batteries every few years. Plus lifetime technical support, greater reliability, and the peace of mind that your electrical system is built to last.

The Best RV Batteries for Winter Camping & Boondocking

Boondocking in winter brings a special joy. With less crowds then the summer, many of our nations parks are best experienced in the off season. From the Tetons in October, when the aspens are golden, to the Badlands in March when the early spring rains bring out the red and orange in the rock, to January in Moab when the sandstone arches are covered in snow.

Winter time does have challenges when boondocking. One is that many RV batteries perform poorly in the winter or do not charge at all, leaving you stranded. That’s why here at Dakota Lithium we focused on developing a battery that can perform in the coldest of conditions. A decade plus later we launched our even heat technology, which uses the energy from the charger to warm the cells to above freezing, allowing for safe and reliable charging in temperatures down to -20F. Here’s the best RV batteries for winter camping.

• Dakota Lithium Plus 12V 135Ah Battery. Discharge down to -40F, with optimal performance between -20F and +160F. Charge down to -20F. Plus, with both 135 Amp Hours of deep cycle energy and 1,000 cca of engine starting power the DL+ 135 is incredibly versatile, allowing you to jump start you RV, truck, or van engine off your house battery if needed. In a compact group 24 case, the DL+ 135 is the best choice for vehicles with a small battery compartment or that need to fit the most power they can into a tight space.
• Dakota Lithium Plus 12V 320h Battery. Same even heat technology allows for charging and discharging down to -20F and the dual purpose BMS allows for jump starting your main engine off of your house battery. The DL+ 320 is the best choice for vehicles that need a lot of power but are short on space. With 320 amp hours of Dakota Lithium capacity in a group 31 case this battery is equal to six traditional 100Ah deep cycle or marine batteries.
• Dakota Lithium Plus 12V 640Ah Battery. Same event heat technology, same ability to jump start your engine in a pinch. The DL+ 640 is the biggest single 12V battery Dakota Lithium makes and is the best choice for vehicles that will need to run AC in the summer and/or have larger electronics like a big flat screen TV.

What Size Solar Panels Do I Need?

Dakota Lithium batteries are the best choice if you are considering adding solar panels to your RV, Van, or trailer because they have the highest efficiency rating for solar power. That means you get more power from each solar panel, and can use more of the power you collect. A deep dive on solar power efficiency is here.

Here’s a size chart for what solar panels you need by size of RV & how many Dakota Lithium batteries you have.

• Size of RV  |  # of Batteries  |  Recommended Solar Panel Capacity | Recommended Off-Grid Power System
  • 10′-14′ | DL 100 Ah x 1 or DL+ 135Ah x 1 | 100 watts of solar (100 watts x 1) | 12V 100Ah Off Grid Solar Power System
  • 15′-20′ | DL 100 Ah x 1 or DL+ 135Ah x 1 | 100 – 200 watts of solar (100 watts x 1 or 2) | 12V 200Ah Off Grid Solar Power System
  • 21′-30′ | 2x DL+ 135Ah or 1x DL+ 320 Ah | 200 watts of solar (100 watts x 2) | 12V 200Ah Off Grid Solar Power System
  • 31′-40′ | 2x DL+ 135Ah or 1x DL+ 320Ah | 400 watts of solar (100 watts x 4) | Dakota Lithium 12V 400Ah Off Grid Power System
  • 40’+ | 2x DL+ 280 Ah, or 1x DL+ 640 Ah | 600 watts of solar (100 watts X 6) | Dakota Lithium 12V 400Ah Off Grid Power System

One thing to note, rooftop solar on RVs and vans tends to have multiple solar panels instead of a single big solar panel. This is because the roof top of a van or RV tend to have vents, like a kitchen vent, or an air conditioner, or a fan or roof vent that make it hard to install a single large panel. To better use the rooftop space consider connecting a number of smaller, 100 watt panels together. This will achieve a higher solar panel capacity. Multiple solar panels also offer redundancy. When there is one glass panel if it shatters you are out of power. Whereas with with multiple panels if one fails you still have solar capacity left.

What Electrical System Upgrades do You Recommend?

Living the dream unshackled from shore power is magical: you have the freedom to go anywhere, and live life on your own terms. Here’s a few upgrades we recommend to build your dream off-the-grid home on wheels.

• Our #1 recommendation for anyone looking to make the lithium upgrade is to make sure that you will be charging your batteries with a lithium compatible charger – it increases performance and saves you time. Dakota Lithium batteries like to be charged at 14.4 volts, which is higher than lead acid. This means that traditional chargers, for shore power, or from solar panels, will work but they will not full charge lithium batteries. For charging off shore power while at home or at RV parks each Dakota Lithium battery will come with a free wall charger that you can plug into any wall socket (or extension cord). For charging via solar panels see if your solar charge controller has a lithium setting (many new ones do) or use a solar charge controller like the Victron Smart Solar MPPT charge controller. Or charge your batteries using the electricity produced by your engine’s alternator using a Orion-Tr Smart DC-DC charger (more on this in a moment).
• If building a new van, truck, trailer, or RV you will need a way to plug in your household electronics. For that you will need an inverter, like the Victron Phoenix watt inverter (for small & mid sized RVs) or the Victron Multiplus (for large RVs and Skoolie’s). An inverter allows you to use 12V Dakota Lithium batteries to power household electronics that require 120V AC (the wall plug in your home). Rated at watts this professional grade Victron inverter takes DC power (the power that comes from batteries or solar panels) and transforms it into AC power. watts is the perfect size for small to mid sized boats, Sprinter or camper vans, RVs, job sites for charging power tools, or other off grid applications where you need plug and play power. watts is a good size to run a medium sized TV, stereo, small kitchen appliances, computers, or other home electronics. If your RV or trailer came with wall plugs then an inverter is already built into your system, and that is compatible with Dakota Lithium batteries.
• If you are looking to spend a lot of time on the road then we recommendation the Orion-Tr Smart DC-DC charger which allows you to charge your deep cycle Dakota Lithium batteries using the alternator in your van, boat, or RV’s engine. The Orion-Tr Smart DC-DC charger is a professional DC to DC adaptive 3-stage charger with built-in Bluetooth. For use in dual battery systems in vehicles or on boats where the alternator and the starter battery are used to charge the service battery (aka house or deep cycle battery). The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch. The Orion Tr-Smart charger can be used in 12V systems and is suitable for both lead acid and lithium batteries.
• For battery monitoring our favorite solution is the Victron Smart Shunt 500A/50MV Bluetooth Battery Monitor. It allows you to monitor the performance of your system using the Victron app on your . Provides real time data on the performance of your system, including how much energy has gone into your batteries from your solar panels and/or from your engine’s alternator, how much energy you are currently using, and how much power you have left in your batteries. Using a battery monitor provides piece of mind, helping you make decisions on when to camp and for how long. It also provides a overview of the performance of your electrical system, which can be helpful if you or a friend need to troubleshoot problems on the road.
