12 8V 300Ah Self-Heating LiFePO4 Lithium Battery with APP Monitoring Low Temp Cut off Built-in 200A BMS Rechargeable

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. Read more

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. Read more

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

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

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.. Read more

I more then like this battery . Customer service bent over backwards to help me set up an older mppt charge controller. Finely got some sun to test everything and I'm very happy with the way the battery preforms. This system has continuous load 24/7 and the 300amp battery has not failed in the middle of the night yet. We are in low light season so if it works now I have no worries as the sun light will get longer. The lifepo4 battery seem to charge quicker then lead acid which means I can charge more batteries with the same wattage solar panels. I have included the settings for the mppt charge controllers. One thing , lifepo4 batteries don't need a float or equalization charge. Unlike lead acid that need a trickle charge to stay topped off once a lifepo4 battery is charged, that's it , done. It could sit for a year and still be charged. If you can't stop the EQ or float set them to 13.8 Set the absorption or boost charge 13.8 for 120 minutes. This company seems to really care about their product so the true test is going to be time. Read more

Use this to power my Starlink through an inverter. Bluetooth is great to monitor charge. Read more

Early days but the 300ah without self heating appears to be a good choice for warmer climates where cold battery temps aren’t an issue. However, note the size is a bit irregular. Not exactly group 31 or group 27 so it was difficult to find a battery tray or box that fit. But I did find that the NOCO BG27 battery box fits perfectly. Read more
