What makes the LiTime 12V 320Ah Mini different from a regular 12V 300Ah LiFePO₄ battery?
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.
How can I monitor the battery's data?
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.
Can I connect multiple 12V 320Ah Mini batteries in parallel or series?
Yes. LiTime 320Ah Mini lithium battery supports support versatile configurations, including series, parallel, and series-parallel connections.
- Series connection: Up to 4 batteries (51.2V total).
- Parallel connection: Up to 4 batteries (1280Ah).
- Series-parallel connection: Up to 16 batteries (65.5kWh).
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)
Is the 12V 320Ah Mini suitable for outdoor and mobile use?
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:
- RVs and van conversions
- Marine systems and houseboats
- Off-grid cabins and solar homes
- Remote work or camping setups
It’s built to perform in harsh environments, including high humidity, salt spray, and extreme temperatures from -4°F to 140°F.
How to charge the 12V 320Ah Mini Battery?
The LiTime 12V 320Ah Mini battery can be charged in four different ways:
1. Solar Panels and Controller
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.
2. Battery Charger
Use a lithium iron phosphate (LiFePO₄) battery charger to maximize charging speed and battery life.
Recommended Charger: LiTime 14.6V 60A Charger
3. Generator + AC to DC Charger
Recommended Charger: LiTime 14.6V 60A Charger
4. Alternator + DC to DC Charger
Recommended Charger: LiTime 12V 60A DC to DC Charger
You can learn more about how to charge lithium battery.
Can Bluetooth and non-Bluetooth batteries be connected in series or parallel?
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.
Is the BMS passive or active balancing?
The small 12v lithium battery uses passive balancing technology, which safely manages cell voltage differences to maintain battery longevity and stability.
Can I replace multiple Group 27/Group 31 batteries with a single LiTime 12V 320Ah Mini?
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.

Great batteries and I would definitely order them again

Long lasting battery!! Perfect for boat.

Shipped in a timely manner. Very well secured in the boxes. I received two 320 amp hour minis hooked them up a couple days ago. They are charging fine on my sailboat. The app works very well also. So far so good. I believe this will be a great product. I also have a 60 amp solar charger that I will be hooking up very soon.
D
Amazing battery!! 320 amp hours in a small package and at a great price. Best house battery ever! Run all your electronics for days!
M
Litime battery was purchased to replace 2 lead acid batteries that came with our camper, this is a huge upgrade to keep our 12v refrigerator going while on the road. Great price from a very reputable company.
C
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.
P
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.
D
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.
