12V 200AH LiFePO4 Lithium Battery with Self-Heating & APP Monitoring, Built-in 200A BMS, Supports Low Temp Charging, 5000+ Cycles, Perfect for RV/Camper, Solar, and Off-Grid Applications, etc.

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 for our camper. Its working great

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!!!!

Awesome battery for the price. Bluetooth works perfect

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.

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..

This is a game changer. After struggling with deep cycle battery's that left me without power way too many times, I finally broke down and spent the money to buy this. Now I can camp multiple days with plenty of power left. Charges back rapidly. I also love that I can check the status on my phone. I am more than happy with this purchase.
