Style: 12V 300Ah Self-Heating
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.

Style: 12V 300Ah Self-Heating
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.

Great company that backs their product!!! I had purchased a couple of their 100ah 12v batteries for my RV battery bank and at some point one of the bms’s failed. I’m not sure when or how long ago as I never noticed any reduced performance with the battery bank. However, when I pulled the batteries to put up for the winter, one was showing just 12.8v and wouldn’t take a charge. It would drop to zero as soon as I put a load on it. Tried to “wake up” the bms with another battery with no results. Made a warranty claim, shipped the battery back to them on their dime and had a new battery within 2 weeks. I would have to say that it appears one of their 100ah 12v batteries has performed the same, if not better than, my former pair of 235ah 6v Duracell batteries. I ran my entire RV, including the heater, for 2-3 days on several occasions and I never seen a resting voltage drop below 13v. I’m very impressed with these batteries. Great customer service and would recommend them if you’re looking for a company that stands behind their product.

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.

Received the battery 3-days early. Battery is light weight but big and came 50% SOC. Won't be able to use until spring. The only negatives is their responses to questions (didn't really answer the questions) So far the app looks nice and gives some information but is not usser friendly when disabling the Chgmos and Dismos which doesn't work. They don't answer the phone, and takes a day to get a response from them by txt which is incomplete or wrong. I will update as time goes on UPDATE: With VATRER giving me the advanced code for overriding the CHGMOS & DISMOS switches it works great. I was able to turn the charging off and turn the output (discharge) off for storage. UPDATE: I'm very happy with the battery and VATRERs support.

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!
