Unit price perKeep Your 24V System Running Longer with 7.68kWh
If your RV or off-grid setup already uses a 24V inverter, you can get 7.68kWh of stored energy from one Vatrer 24V 300Ah lithium battery instead of wiring two 12V batteries in series just to reach 24V. With up to 5120W of load power, it can support air conditioning, refrigeration, lighting, fans, and other everyday loads while giving you more time between charges.
Automatic Self-Heating Restores Charging in Freezing Conditions
After a freezing night, this Vatrer 24V 300Ah self-heating lithium battery checks battery temperature as soon as charging input is connected. At 32°F or below, the incoming power is used to warm the battery while charging remains paused. Once the temperature rises above 41°F, heating stops and charging starts automatically, without using stored battery energy to run the heater.
Recharge from Shore Power Solar or a Generator
At a campground, a 60A LiFePO4 charger can recharge the battery in about five hours under the stated charging conditions. When you are camping away from hookups, you can recharge from solar through an MPPT controller, and a generator with a DC-to-DC charger gives you another option when solar production is limited. That flexibility makes it easier to keep a large 24V battery charged whether you are plugged in or staying off-grid.
200A BMS Protection for High-Load Operation
Air conditioners and other high-draw appliances can place a heavy current demand on your battery system. The built-in 200A BMS manages charging and discharging while providing protection against overcharge, over-discharge, over-current, short circuit, and abnormal temperatures. You get the current capability needed for demanding 24V loads with battery-level protection working automatically in the background.
Check Battery Status from the Vatrer APP
With a battery mounted under a seat or inside a storage compartment, with the Vatrer APP, you can view the state of charge, voltage, current, temperature, and operating status from your phone. This makes it easier to see how the battery is charging, how much energy is left, and what is happening during everyday use without opening the battery compartment.
Add More Capacity as Your Power Needs Grow
You may start with one 7.68kWh battery and need more storage later as you add appliances, longer off-grid stays, or a larger solar system. The battery supports configurations up to 4P2S, allowing the system to expand to as much as 61.44kWh. You can build around the capacity you need now and add matching batteries later instead of replacing the original battery when your energy needs increase.
5000 Plus Deep Cycles for Long-Term Daily Use
RV travel and off-grid solar can put a battery through frequent charge and discharge cycles throughout the year. This 24V 300Ah LiFePO4 battery uses Grade A cells and is 5000+ deep cycles, that means fewer battery replacements for customers who rely on stored power day after day.
Built for RV Off-Grid and High-Runtime 24V Use
A 300Ah lithium battery makes the most sense when your 24V system needs more runtime than a smaller 100Ah or 200Ah battery can provide. In an RV, that can mean longer use of air conditioning and household appliances between charges. In an off-grid cabin or solar setup, it gives you more stored energy to carry through the night or periods of limited solar production. It can also support 24V marine setups where longer runtime is a priority. The IP65 enclosure helps protect the battery from dust and everyday moisture, while integrated handles make installation and repositioning easier.
Get Your 24V System Ready for Year-Round Use
If your 24V system is ready for longer trips, colder seasons, or more time away from hookups, this Vatrer battery is built to stay with you through those plans. Add it to your setup now and head into your next trip with a battery that is ready to work when you need it.

FAQs
Yes. When the battery temperature is 32°F or below and charging current is above 5A, incoming power is directed to the heating system first. Once the battery warms above 41°F, heating stops and normal charging begins. If weak winter sunlight cannot provide enough charging current to activate heating, use a 29.2V LiFePO4 charger or a generator with a suitable DC-to-DC charger to provide a stronger charging source.
No. Our self-heating system is triggered by charging input rather than using stored battery energy to keep itself warm overnight. In freezing weather, connect an available charging source when you are ready to recharge; the incoming power will warm the battery first if its temperature is too low for charging.
Yes. Charging and discharging have different low-temperature limits. The battery can continue supplying power below 32°F, while the BMS provides low-temperature discharge protection below -4°F. If that protection activates during extreme cold, warm the battery compartment before resuming normal use; the built-in heater is intended to prepare the battery for charging and does not operate from stored energy during discharge.
Store the battery between 14°F and 122°F in a dry location and disconnect unnecessary loads before extended storage. An insulated RV compartment, garage, or other protected location helps reduce prolonged exposure to temperature extremes. When you return to a freezing battery, connect a suitable charging source and let the automatic heating cycle complete before charging begins.
Yes, when the battery is used as the 24V side of the RV electrical system. A 24V inverter can supply your AC loads, while 12V lights, water pumps, controls, and other 12V equipment can be powered through a properly 24V-to-12V DC converter. This keeps the high-power side at 24V without requiring you to replace every 12V appliance in the RV.
We recommend a 29.2V LiFePO4 charger, with a 60A charger providing a practical charging rate for this 300Ah battery. Avoid chargers that rely on lead-acid equalization or charging profiles that are not designed for LiFePO4 chemistry. A dedicated LiFePO4 charging profile lets the battery and BMS work within the intended charging range.
Yes, through a correctly configured DC-to-DC charging system. A 12V vehicle alternator should not be connected directly to this 25.6V battery; use a DC-to-DC charger that converts the vehicle-side voltage to the proper 24V LiFePO4 charging output. This also regulates charging current instead of placing an uncontrolled load on the alternator circuit.
This battery supports configurations up to 4P2S. For a multi-battery system, we recommend using the same Vatrer model with the same voltage and capacity, and bringing the batteries to a similar state of charge before connecting them. Keep interconnect cable size and length consistent so parallel batteries share current more evenly rather than placing more load on one battery.
Not if extended runtime is the goal. A 300Ah battery provides substantially more stored energy than the 50Ah or 100Ah batteries commonly used with 24V trolling motors, making it better suited to long fishing days, heavier boats, stronger current, or trips where frequent recharging is inconvenient. The trolling motor's operating current should remain within the battery's 200A BMS capability. This is a deep-cycle battery and is not intended to replace an engine starting battery.
Yes, an IP65 enclosure provides protection against dust and water jets encountered in normal RV, marine, and off-grid installations. We still recommend a protected battery compartment rather than leaving the battery exposed to standing water, submersion, or continuous direct weather. A sheltered installation also helps control battery temperature in both summer heat and freezing winter conditions.
