Hot LiTime LiHeat® 12V 320Ah Mini Dual-Mode Self Heating Lithium Battery for RV, Camping and Off-Grid

Huge capacity, heated, great Bluetooth range! I replaced two 100Ah LiFePO4 batteries from a certain blue brand that used to be very popular with RVers and is now known to be a terrible design. Thanks for the tear downs Will Prowse! This 320Ah LiTime Mini Heated battery is amazing. I wanted to keep my existing (fairly small) aluminum battery box on the tongue of my RV, maximize capacity, and have a single heated battery. This is the ONLY one which fits in such a small space and provides so much capacity. The ability to choose the heat source (charger or battery) is awesome. The build quality is great, much better than you might expect for such a good price. The iOS app is really good, too. It’s simple, clean, fast, and provides everything you need and nothing you don’t. I was worried about the Bluetooth range (I have an aluminum tongue box) but no worries! My RV is parked on the side of my house and I can connect to the battery from inside my house through two interior walls! Battery tech has improved so much over the last few years and this one is evidence of that. If you’re looking for a high capacity 12V battery I would not hesitate to buy this one.

320AH Mini self heating batteries I have been researching which lithium iron phosphate battles I wanted for our new to us 2019 class C RV and settled on the 2 pack LiTime 12V 320 AH Mini Self heating batteries. The only challenge I had was getting the batteries safely shipped to Alaska since most all Lithium battery companies do not ship to Alaska. But we can use barge services from the Seattle / Tacoma to get things like these shipped up here. I also wanted to wait until the temperatures on the ocean were warm enough to ship the batteries. The batteries arrived as planned in two very well foam insulated boxes that measured 20”W X 17”T X 14”D. I turned the batteries on and both were charged to 52% (recommended storage percentages) and both were at 13.4 volts. Once verified and tested I turned them back off while we wait for our snow to melt and for spring to arrive. So far I’m very pleased. The true test will come in a month or so.

Excellent battery, app, and excellent value. Haven't gotten to use the self heating function yet, but the app is great, the battery is great. I've used a couple other apps and lithium based batteries before and so far these beat them hands down, especially for the price point. I really look forward to the 12v 100ah slim that is being released. Simply amazed at the capcity for their size.
