Product Review
When manually choose “Energy-Efficient” mode to initiate preheating through LiTime app, it enables the battery to utilize its own stored energy for self-heating if SOC>20% .
Regular Mode: Heats the battery via an external charger.
Energy-Efficient Mode: Self-heats using its own power, shortens warm-up time.
Yes. The 320Ah self heating lithium battery can safely charge between -20℃ to 50℃ ( -4℉ to 122℉). The 2 self-heating modes will start heating the battery before charging.
No. This battery is not intended to be used as starting batteries but energy storage, please do not use them to start any devices.
This LiTime 12V 320Ah Mini with Self-Heating delivers more energy with less bulk. It's 35% smaller than typical 12V 300Ah LiFePO₄ batteries and 70% lighter than three 100Ah lead-acid units—while offering a high-energy 4096Wh output and up to 200A continuous discharge. That means you get max energy density, easier installation, and better portability—all in one compact unit.
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.
I received my order in a timely fashion and they are working perfectly.
Working great as a house battery for my travel trailer supplied by 400w of solar. Has the power to take care of lights and 12v fridge without a shut off during storage. Awesome battery.
I am still amazed at the compact capacity of this amazing battery. It fit snugly in the battery box in my truck camper that USED to hold a mere 88Ah marine deep cell. The swap out was easy and now I can boondock carefree!
Great product for my semi truck. Works great and the Bluetooth app works great as well. All I need now is a dc to dc charger and I'll be set
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.
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.
Great product. Works as advertised
