How does the new self-heating function work?

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% .

What are the differences between 2 Self-Heating Mode?

Regular Mode: Heats the battery via an external charger.

Energy-Efficient Mode: Self-heats using its own power, shortens warm-up time.

Can I charge 12V 320Ah Self heating Lithium batteries under freezing temperatures?

Yes.  The 320Ah self heating lithium battery can safely charge between -20℃ ( -4℉ ). The 2 self-heating modes will start heating the battery before charging.

Can I use this LiTime 12V 320Ah Self-Heating Lithium batteries as starting batteries?

No. This battery is not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

What makes the 12V 320Ah Mini self heating different from a regular 12V 300Ah battery?

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.

I have installed three 320 ah mini batteries in my RV

I have installed three 320 ah mini batteries in my RV. So far they are performing as they should and I am pleased with the purchase.

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.

I am still amazed at the compact capacity of this amazing 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!

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.

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.

RV Battery Tech Has Changed Faster Than Anyone Realizes

Battery tech has come a long way in just two years. ⚡️ In this video, we break down how we upgraded from our original 12V 100Ah LiTime battery to their newest 12V 320Ah self-heating battery — all while keeping nearly the same footprint. That’s almost 3× the usable power, better cold-weather performance, and a huge upgrade for boondocking and off-grid living. If you’re building or upgrading an RV or van electrical system, this is a perfect example of how fast lithium battery technology is evolving.
