12.8V 100AH Group 31 LiFePO4 Lithium Battery with Self-Heating & APP Monitoring, Built-in 100A BMS, High Temp Cutoff, Low Temp Charging, 5000+ Cycles, Perfect for RV/Camping,Off-Grid,Solar

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.

Why did you pick this product vs others?: I bought this after sending back another Li battery that was just a train wreck. The Vatrer used to be a piece of crap with really poor build quality, but recently they have totally reworked the design into a really solid item at a great price. Mine arrived at about 60% charge, instantly started charging and balancing when put into my solar system. The 4 cells are usually with .001 volt of one another at all times so it stays amazingly well balanced. It's the plug and play Li battery I was hoping for. Will Prowse has a new video mentioning this battery and the build quality (the 3 year old video of the same shows the old battery now d/c'd.) The Vatrer app is easy to use and is within 1% of the reading of my Victron shunt, so maybe not perfect but certainly close enough for practical use.

The “manual” was actually pretty good. Packaging was completely adequate. The heated battery function works well and faster than I anticipated.

Perfect, I will order additional batteries in the near future!!!!

So far so good, I’ve had it hooked up for about 2 weeks now and I can’t get it to die. Meets my needs perfectly.. app works good and was a breeze to install on my tt! Battery is not to heavy and fits great after some fabrication to the tongue of my trailer..

Light weight. Great power house. Highly recommended. Will buy another one at the end of this month for a series connection.

Awesome battery for the price. Bluetooth works perfect

There is a -1.8 to -2.6 drain on the battery at night. Probably feeding the BMS but not sure.
