Features
- Automatic Self-Heating12V 300Ah LiFePO4 battery model is equipped with an automatic self-heating function that will be activated by the BMS when the battery is connected to a charger at -4F to 41F. The heating will be stopped when the battery temperature reaches 41F and then the battery will be formally charged. This feature makes it no problem to charge the battery at low temperatures. The battery's working environment is no longer restricted, but more flexible and convenient to use.
- Grade-A Cells & Upgraded 200A BMSVATRER POWER 300Ah self-heating LiFePO4 batteries with Automotive Grade LiFePO4 cells have uncompromising quality and higher energy density with better stability, which makes it possible to ensure long-term recycling. And highest-level safety is based on UL Testing Reports for the cells inside the battery and upgraded BMS with heating pads to protect it from overcharging, over-discharging, over-current, and short circuits with excellent self-discharge rate.
- Exceptional Longevity & Lightweight Our LiFePO4 lithium iron batteries provides 5000+ cycles compared to 300~500 cycles in lead acid battery. The service life of LiFePO4 batteries is 8 to 10 times than the standard lead-acid batteries. Helping to minimize replacement cost and reduce total cost of ownership. And the weight of the lithium iron phosphate battery is 30% lighter than the lead-acid battery of the same capacity, so you can carry it more easily.
- Safety & Unlimited Solar Energy The stable Lithium Iron Phosphate chemical structure makes LiFePO4 battery not burn or explode even at high temperature, short circuit, impact and drop. Highest-level safety based on UL Testing Certificate for the cell inside the battery. And it does not contain any heavy metals and rare metals and is more energy efficient, clean, green charging , which called green battery.
- Multi-Application With no acid in the lithium ion battery, you're able to safely mount in any position. This makes li-ion batteries perfect for marine, RV, campers, travel trailer, and off-grid applications! NOTE: The battery is suitable for energy storage rather than start-up. Please consult us in advance if needed.
- Kindly AttentionThis battery with self-heating can not be connected with the regular version 12V 300Ah battery model in series or in parallel. The battery will activate the heating function only when the charging current is more than 10A.
- NOTEThe 300Ah heating battery adopts our latest appearance design. All the configurations are the same as the previous version. It can still be connected in series or parallel with the earlier version.

Great, affordable RV upgrade. I replaced a 100AH stock AGM battery with the 300AH LifePO4 this summer. Swap was easy. My panel is Lithium compatible so all I had to do was flip a switch and figure out a mounting solution under my dinette that fits the larger footprint battery. I can't compare performance to high-end Lithium batteries but this is excellent compared to the stock battery. Charges quickly runs our on-board electronics. I have a briefcase-style solar panel with built in controller that works well. The app is simple but nice to have. It gives all the data you need to monitor the battery, whether it's charging, temp, etc. It's also really nice to use the app to understand how much power the appliances are drawing in real time. The Bluetooth signal reaches about 20 yards so if I go to the corner of my house closest to where I park the camper, I can connect and check the stats. One season of use and no issues. I keep the battery installed and the RV connected to shore power all winter (Western Washington mild-winters) so will wait to see how the cold protection works out. Overall, very happy with the purchase. At this price, it's definitely an improvement in weight and performance over an AGM and from what I've observed after one camping season, I don't see a reason to spend 2 or 3X more for a higher-end battery that's the same size.

Excellent battery that has performed flawlessly in our motorhome. Customer service is stellar, I had ordered the wrong model by mistake and they went the extra mile to help me get what I wanted. Emails were promptly answered and every attempt was made to ensure my satisfaction. The battery itself is well made by the website description, I believe this is a serious company using quality components. From my experience with other lithium battery brands this is a superior product. The phone app is easy and simple showing useful real data instead of cartoons as some other companies use. Bluetooth range is exceptional, I can open the app and read battery status in the closed motorhome from inside my house. Cell balance stays within .001v after overnight settling from a fresh charge, can't beat that! Our motorhome is power hungry with a compressor fridge so dry camping used to be painful, but not now! Our 380 watt solar panels bring the battery to full charge every day. Even when missing a day or two sunshine there is so much capacity I am worry free. I've mounted the battery inside our unit in an empty storage compartment, one of the advantages of LiFePo4 batteries. Keep in mind that all lithium batteries have a proprietary charging profile, so if you are currently using either AGM or wet cell batteries you will need a DC to DC charger along with adjusting some other electrical settings as they are not directly interchangeable. Very happy with my purchase, thanks Vatrer for a great product!

This battery is awesome! I installed it into my travel trailer, replacing 2 heavy 6-volt golf cart lead acid batteries. I think this is going to work much better (more power as it drains down further without damaging the battery). The heating function will be appreciated on my late fall hunting trips. I did have to replace the trailer battery charger electronics, but well worth and not that hard to do. The software and Bluetooth connection is great. I can sit in my trailer and check the status of the battery, including what my solar panels are providing. Can't wait to take it out on. my next trip!

I had been wanting to upgrade to lithium power for my motorhome for a while and these batteries made it easy to do! I ended up installing two 300 amp hour batteries and they have been fantastic. Tons of power storage in a very small area. Construction is heavy duty and has a built-in BIM as well as Bluetooth connectivity so you can check on the health of your battery at any time.

Excellent battery so far. The built-in BMS and heater made this battery a no brainer to replace the deep cycle batteries in our 2017 Airstream 27FB. It's too big for the battery box, but I knew that going into it and was planning to relocate the battery to inside the front baggage compartment anyway, so that's what I did. We like to boondock (camp off-grid), and while we don't yet have solar panels, I upgraded the converter in the Airstream to one that can provide the proper charging voltage for LiFePO4 batteries, as well as a Victron DC-to-DC charger enabling them to charge off our Suburban while we're in transit to a different campsite. The battery runs our lights, my CPAP machine, vent fan, stereo system, charges our phones and tablets, and we have a 1000w inverter that runs the TVs and our laptop chargers. We can now go several days without needing to charge this battery. When we do charge it, the converter pumps 30 amps into it from our 2000w generator, taking me from 30% to 90% in a few hours. With 5 gallons of gas, we can stay out in the wild for 2-3 weeks, no problem. It's been a game changer for us.

Purchased this battery to replace a 12v Lead Acid Deep Cycle battery that came with our Forest River R-Pod 192. This is a much bigger battery so I had to buy a battery box and install that. Happy overall with the battery capacity. Did run into some trouble connecting to the battery via the Vatrer application on an iPhone 14 Pro. Contacted customer support who assisted with troubleshooting and sent out a replacement battery in November 2025. That battery has just been installed and it is working great. Definetly love the battery capacity. Good battery for the price. Would buy again.

Tested this battery in my Class A motorhome last week running a full-sized fridge, heater fan (propane heat), TravlFi router, satellite tv & two led tv’s, water pump and any/all lights as needed. Ran for 17 hours and went from 100% SOC to 21% SOC. That’s only 4.647% used per hour!! Which means I could have run an additional 4.5 hours (totaling 21.5 hours) before the battery was fully discharged! When I returned home I charged this battery using a 20amp Vatrer 14.7v charger and it only took 4.5 hours to reach 50% SOC (for storage). This should calculate to another 4.5 hours to get this 300ah battery to 80% SOC! At 20amps! I will report on actual load/charge numbers when I install my new LiFePo compatible inverter/charger that charges at 50amps which should cut my charge time by half!! My current system of 4 6v AGM batteries totaling 450ah would only run this load for @ 8 hours down to @ 12.2v and would take three 3 hour generator charging sessions during the day/evening to get them back to 12.8v to run the same load overnight. Theoretically if I ran the same load overnight for 10 hours using my new setup with this Vatrer 300ah battery and a 50amp charger, then it should only reach 53.53% SOC and charge back up to 80% SOC in just over 2 hours of generator power. Top it off with 400watts of solar to get to 100% SOC and I’ll be good! I can’t wait to go back to our favorite boondocking spot and no longer be branded as the noisy generator guy! Great product Vatrer!!!

Battery came nicely packed. Opened to find what appeared to be a top notch battery. Installed the app right away and it hooked up to Bluetooth flawlessly. The app works very well with no options on it to make any changes. Connected it into my boat system but had to get longer studs since I have five ground wires that needed to be hooked up. So far I have been pleasantly surprised. According to the app it seems to hold 300 amps at full charge. I haven't put it to the test but I will be taking a trip with the boat in April. Updates to come. So far so good.
