Keep Charging Through Freezing Mornings
After a cold night in your RV or cabin, charging power can arrive before the battery itself has warmed up. When a charger is connected and the cell temperature is at or below 32°F, the BMS directs charging input to the heating system first instead of charging the cells. Once the temperature rises above 41°F, heating stops and normal charging begins automatically. With this self-heating lithium battery, you can leave the battery installed while the system handles the warm-up before solar, shore power, or vehicle charging replenishes your energy.
3.84kWh for Longer RV and Off-Grid Runtime
A refrigerator running overnight, lights after sunset, a water pump, fans, electronics, and other daily loads quickly add up when hookups are not available. This Vatrer 12V 300Ah LiFePO4 battery stores 3.84kWh of energy, giving you more room to stay comfortable between charging opportunities. Whether you are boondocking in an RV or running a remote cabin, the larger battery reserve helps reduce your reliance on generator time or the next available power source.
200A BMS Power for High-Demand 12V Loads
Turn on a coffee maker while your refrigerator, lights, and water pump are already in use, and current demand rises quickly. The built-in 200A BMS supports up to 2,560W of continuous output, giving this RV lithium battery the headroom for higher-demand 12V systems and inverter-powered appliances.
Flexible Charging at Camp and on the Road
At a campground, you can recharge with a LiFePO4 battery charger. While boondocking, solar panels and an MPPT controller can keep energy coming in during the day. On travel days, a DC-to-DC charging setup can use vehicle power to recharge your Vatrer 12V 300Ah lithium battery while you drive.
Battery Status on Your Phone
Before turning in for the night, you can see how much battery capacity is left without opening the RV battery compartment. Bluetooth monitoring through the Vatrer app shows state of charge, voltage, current, temperature, and operating status on your phone. You can see how the battery responds to active loads and decide whether to recharge the next day or adjust overnight power use.
Scale Up to a Larger Off-Grid Battery Bank
Start with one battery for your RV or cabin, then expand the system as your solar and inverter needs grow. This 300Ah self-heating LiFePO4 battery supports expansion up to a 51.2V 1200Ah battery bank, giving your off-grid lithium battery system room to grow with larger energy demands.
Flexible Installation for Tight Battery Spaces
An RV storage bay or off-grid equipment cabinet rarely gives you unlimited room. The battery's internal structure supports horizontal or vertical installation, giving you more flexibility around the space available. An IP65-rated ABS case adds protection against the dust and moisture commonly encountered around RV and off-grid equipment areas.
4,000+ Deep Cycles for Long-Term Use
Over years of RV or off-grid use, battery replacements and lead-acid maintenance add time and cost. This deep cycle lithium battery is rated for 4,000+ cycles, giving you a longer service life than a typical lead-acid battery while making more of the stored capacity available for daily use.

Tech Specs
These were recommended by Will Prowse. These have been flawless I run 2 in parallel and have enough power to run my chill cube for hours!
I just got the installed. Paired the with a Victorian multiplus ii and the run the ac perfectly. Bluetooth has worked great. I with there was away to connect them to the Victron system but I know that would add to the cost. Time will tell.
Battery working Flawlessly . Boon docking will no longer be a problem.
Feature loaded for the price, impressed with the Bluetooth app, simple but 100% . Check put this YouTube, a comparison between a lot of 300 amp hour batteries. See which one comes out on top.

Just what I needed for’ boon-docking’!
The batteries were delivered on time. They work properly. The sizes were accurate. I received them in April in MN so ... ya, it was able to still solar charge under freezing temps. Very Happy
Other than Fed X delivering batteries 5 days apart everything else has been great. Installed in motorhome and they are staying balanced and recharge quickly. Bluetooth works great.
These batteries are great! Self heating! The app is amazing. I have already had a great experience with customer service. I’ve done a lot of research and these are the best Batteries!
Everything GOOD nothing bad. Delivered on time with 50% charge. Downloaded the app and immediately pulled up the batteries. App is flawless. After charging and balancing the batteries they were installed. I am very impressed. Vatrer is my go to battery.
Seems to be a great battery. When I tried to pull more than 200 amps, the BMS shut it down like it is supposed to do. 2 of them, in parallel, power my 3500 watt inverter perfectly. A lot lighter than 3 group 29 deep cell batteries.
FAQs
No. Our heating system is triggered by charging input rather than continuously drawing stored battery energy while your RV is parked. When the cells are at or below 32°F and a charging source supplies more than 10A, incoming power is directed to heating first. Normal charging begins after the cells warm above 41°F. If the battery is sitting cold with no charger connected, the heater does not keep running and drains your 300Ah capacity.
The heating function needs more than 10A of charging input to activate. Early-morning or weak winter solar may not provide enough current immediately, so use a LiFePO4 charger or DC-to-DC charger when you need to warm a cold-soaked battery without waiting for stronger sunlight. Solar can take over normally once available charging current is sufficient and the cells have warmed above 41°F.
Yes. Freezing weather does not automatically mean you lose house power overnight. This Vatrer 12V 300Ah LiFePO4 battery can discharge at temperatures below 32°F, with low-temperature BMS protection preventing operation once conditions become too cold.
No. We designed this 12V 300Ah lithium battery for deep-cycle house power and energy storage, not engine cranking, and it does not carry a CCA function. Keep a dedicated starting battery for your RV engine or generator starter. Use this Vatrer battery for the house side of the system where its 300Ah capacity can run appliances, electronics, lighting, and other daily loads.
Yes, through a DC-to-DC charger. We recommend placing the DC-to-DC charger between the vehicle charging system and the RV lithium battery rather than connecting the LiFePO4 battery directly to the alternator. This regulates charging current and voltage while protecting the vehicle charging system.
A converter with a LiFePO4 charging profile is the right match. Our battery accepts a 14.2V–14.6V charging voltage, while older converters that remain around typical lead-acid float voltage may leave part of the 300Ah capacity unused. Disable equalization and desulfation modes. If your existing converter does not provide a lithium profile, replacing the charging section or adding a dedicated LiFePO4 charger gives the battery the correct charging cycle.
Not as a continuous 3000W load from a single battery. The built-in 200A BMS supports up to 2,560W of continuous battery output, so a 2000W inverter provides more operating headroom for one 300Ah LiFePO4 battery. If your system regularly needs around 3000W, use multiple identical batteries in parallel so the current is shared across the battery bank instead of pushing one BMS beyond its continuous rating.
Plan around 850W or more of solar with a 12V MPPT controller when your goal is to recover a large portion of the 3.84kWh capacity during a good sunny day. Our 850W solar example reaches about a 4.5-hour recharge under favorable sunlight. Winter installations benefit from combining solar with DC-to-DC or shore charging because shorter days and self-heating can reduce the amount of solar energy available for actual battery charging.
We recommend building the bank with identical Vatrer 12V 300Ah self-heating lithium batteries rather than mixing capacities, BMS ratings, heated and non-heated models, or different battery chemistries. Before connecting multiple batteries, bring them to a similar state of charge and voltage. Use balanced cabling when connecting them in parallel. This keeps current sharing more even as you expand the system up to the supported 4S4P configuration.
Yes, as long as the storage temperature remains within the battery's 14°F to 122°F storage range. In an unheated RV, cabin, or equipment compartment, disconnect unnecessary loads during long-term storage and keep the battery protected from standing water even though the case is IP65 rated. The heater does not continuously warm the battery while it is stored, so if the compartment will remain below 14°F, move the battery to a warmer space or use a temperature-controlled enclosure until the battery returns to service.
