12V 200AH Bluetooth LiFePO4 Lithium Battery with Self-Heating, Built-in 200A BMS, Supports Low Temp Charging(-4°F), 5000+ Cycles, Perfect for RV/Camper, Solar, and Off-Grid Applications, etc.

Used it once in my camping trip and it worked great with 1KW inverter and I also was able to charge it with my pickup inverter with 110v charger when driving.

I’m really glad that I chose a battery with Bluetooth. Seeing the state of charge, battery temperature, and watts in and out is really useful. Seeing the data makes me feel confident that the BMS is functioning properly. The battery case and terminals are well made and overall impressions are very good. It does come with battery terminal bolts and plastic terminal covers. I have only been using it for a few days but so far I’m pleased with the capacity and performance. I’m changing the battery with an MPPT solar charge controller and 2x 100 watt panels in series. It takes about 2 days of full sun to recharge with 200 watts of solar this time of year. You will need a charger with the option to charge LiFePo4 batterie, which are charged at a higher voltage and different charging profile than lead acid batteries. I’m not pushing the limits of this battery with my application and I’m happy with the way things are going. I expect a long life for the battery. It’s important for consumers to understand that LiFEPo4 batteries like these are not suitable for starting vehicles (not enough amps). These are ideal for solar power systems, camping, and backup power. They are relatively safe and can be fully charged and discharged without risking significant damage the battery (as is the case for lead batteries)

Working great this summer in my camper. Added a DC to DC charger to keep it topped off from my tow vehicle. Along with solar panels to keep it topped off when parked. Now I've got all the power I need when off grid.

Great battery

I use two of these in parallel as the 'house' battery on my small sailboat. The cells perform similarly to batteries I have assembled from decently matched 'A' grade prismatic cells. (I had a small business custom building LiFePO4 batteries for a bit over a decade.) The Bluetooth capability of the JBD BMS provides good detail in order to cross check with the Victron monitor and solar MPPT charge controllers I've installed. A BMS failed in one battery, giving me a test of Vatrer's customer service and warranty process. They shipped a replacement battery quickly and provided a return label for the failed battery. I can't build batteries for this price, and the support from Vatrer has been excellent.
