Why This Battery Changes Everything
The LiTime 12V 320Ah Mini battery delivers more energy with less bulk. It's 31% smaller than typical 12V 300Ah LiFePO₄ batteries and 55% 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.
You can easily monitor real-time battery performance via the LiTime App with Bluetooth 5.0, including:
• State of charge (SOC)
• Real-time voltage, current, and power
• Charge/discharge and standby status
• Battery temperature
• Cycle times
• Remaining capacity
This makes it simple to manage your power from your phone, wherever you are.
Yes. LiTime 320Ah Mini lithium battery supports support versatile configurations, including series, parallel, and series-parallel connections.
Important Notes: For safe and stable operation, all connected batteries must meet the following criteria:
✔ Same specifications – Identical capacity (Ah) and BMS rating (A)
✔ Same brand – Different brands may have incompatible BMS settings
✔ Purchased within a short timeframe (ideally within one month)
Absolutely. With its IP65 waterproof and dustproof rating, rugged housing, and compact design relative to its size (15.12*7.64*9.76 in), the 320Ah Mini is well-suited for:
It’s built to perform in harsh environments, including high humidity, salt spray, and extreme temperatures from -4°F to 140°F.
The LiTime 12V 320Ah Mini battery can be charged in four different ways:
Recommended Solar Power: ≥1300W
The battery can be fully charged in one day using 1300W solar panels, assuming effective sunlight for about 4.5 hours.
Use a lithium iron phosphate (LiFePO₄) battery charger to maximize charging speed and battery life.
Recommended Charger: LiTime 14.6V 60A Charger
Recommended Charger: LiTime 14.6V 60A Charger
Recommended Charger: LiTime 12V 60A DC to DC Charger

It is strongly not recommended. Only Bluetooth-enabled batteries can be monitored individually, while the system as a whole cannot be tracked. Mixing them may compromise total capacity and system performance.
The small 12v lithium battery uses passive balancing technology, which safely manages cell voltage differences to maintain battery longevity and stability.
Yes. In many RV and marine systems, two or three Group 27 or Group 31 batteries are used to reach around 250–300Ah. The LiTime 12V 320Ah Mini battery delivers similar or greater capacity in one high-density LiFePO₄ pack.
Even though the Mini is slightly longer than a single Group 27/31 battery, the overall system becomes smaller and lighter because you no longer need multiple cases, trays, and interconnecting cables. This makes it a smart upgrade wherever space is tight—like under RV seats, in van cabinetry, or in compact boat lockers.
I’m using 2 of these in my truck camper in a 24v main battery bank. About to go with 4 because I’ve made the room. These 320ah batteries are game changers.
We tried dry camping and our 2 6v la's would only run us for about 14 hours. Took advantage of the holidays sales, purchased the two-pack giving us 640ah of usable power and a 60-amp AC charger. Super easy swap, one switch to flip, one controller to reprogram, a couple new boxes and some wiring. Had a power outage and the RV fridge was on with two air dryers, Ran for 24 hours before I noticed, checked the app and batt's were only down to 83 & 91 percents. This is going to work big time.
It arrived in a well packed box. it was bigger than my mind imagined but the measurements were correct. I had to take out the tray in my battery compartment if I wanted to put the cables on. Downloaded the app. Got it placed and hooked up then adjusted my charger for lithium and got the app synced to the battery. I love the real time data for charging and capacity and use. Haven’t started our travels yet but everything seems to be working. Looking forward to our trip.
We purchased this battery as an extension of our solar generator setup. Its dimensions made it a perfect fit in our van compartment. Our system was put to the test this Thanksgiving weekend. With temperatures in the low forty’s and a steady light rain for two days, the battery worked as expected and helped keep us warm at night.
We enjoyed cooking, morning coffee and more with the battery, as the weather prevented using our solar panels. With this battery we can go days without solar backup, or idling our vehicle to use the alternator charger. Well worth the investment.
A family member camping with us was so impressed, they are going to purchase some Li Time batteries for their truck camper.
I received 2 of the 12v 320ah Mini batteries in excellent condition. I charged each battery fully before wiring in parallel. After letting them equalize I noticed that the firmware is not the same version and I hope that won’t be an issue. I haven’t put them fully to the test yet but so far everything is good. Lots of energy in a compact size.
Set up with the inverter and battery monitor. When I was calibrating the battery monitor, it took about 40 to deplete the batteries with the TV, 12volt refrigerator, and all the LED light on in my RV to deplete the batteries. Very happy with the batteries. It does take longer to recharge them than I had hoped. From completely depleted to 100% using 50 amp connection took about 12 hours.
These batteries work as advertised. I did the installation on a 41-foot cabin cruiser for house power. I was surprised when I had 8 hours of run time available for my aft air conditioner.
Impressed with the size and capacity of this battery. Can't speak to the long term reliability of this product, but have been happy with the old "Ampere Time" batteries.
