What makes the Xtra Mini 12V 100Ah battery different from a regular 12V 100Ah LiFePO4 battery?
The Xtra Mini is 50% smaller and 23% lighter than standard 12V 100Ah LiFePO4 batteries. It's ideal for users who have limited space in RVs, small boats, camping setups, or DIY solar systems. Despite the compact size, it still delivers a full 1280Wh of energy with 100A BMS support.
How can I monitor the battery's data?
You can monitor real-time battery data through the LiTime App, including:
- State of Charge (SOC)
- Voltage
- Current (charge/discharge)
- Battery temperature
- Cycle count
- Remaining capacity
Can I connect multiple Xtra Mini batteries in parallel or series?
LiTime 12V batteries support versatile configurations, including series, parallel, and series-parallel connections.
- Series connection: Up to 4 batteries
- Parallel connection: Up to 4 batteries
- Series-parallel connection: Up to 16 batteries
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)
Can I use Xtra Mini Lithium batteries as starting batteries?
No. As deep cycle batteries, the xtra mini batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.
Visit LiTime marine starting batteries for starting needs.
Is the Xtra Mini suitable for outdoor and mobile use?
Yes! With its IP65 rating, rugged case, and compact size (10.2 x 7.1 x 8.2 in, 19.77 lbs), the Xtra Mini is ideal for:
- Kayaks and small boats
- RVs and van life
- Camping battery boxes
- Off-grid portable systems
How to Charge Your LiTime 12V 100Ah Xtra Mini Battery
1. LiFePO4 Battery Charger
For the most reliable performance, use a 14.6V LiFePO4 smart charger.
Charging Specs:
- Recommended Voltage: 14.2V – 14.6V
- Charging Current Options:
20A (0.2C): Full charge in ~5 hours
50A (0.5C): Up to 100% charge in ~2 hours
2. Solar Panels
With 400W solar panels and around 4.5 hours of effective sunlight, you can fully charge the battery in a day.
- For systems ≥400W, actual charge time may vary depending on sunlight intensity and duration.
- Use a compatible MPPT solar charge controller to ensure safe and efficient charging.
3. Generator or Vehicle Alternator
- DC Output (Alternator): Requires a DC-DC charger to safely connect to the battery.
- AC Output (Generator): Use a LiFePO4-compatible AC charger between the generator and battery.
Charging Specs:
- Voltage: 14.2V – 14.6V
- Current Options:
20A (0.2C): Full charge in ~5 hours
50A (0.5C): Charges to ~100% in ~2 hours
Can I charge LiTime Xtra Mini small lithium batteries in cold weather (under freezing temperatures)?
LiFePO4 batteries can safely charge between 0℃ to 50℃ / 32℉ to 122℉. LiTime XtraMini lithium battery include the low-temperature charging protection which will automatically cut the battery charging off when the cell temperature is lower than 32℉, thus preventing the battery cells from damage when charging under the freezing point.
It's recommended to charge the battery indoor when it's cold day. For more detailed guidance, visit the LiFePO4 Temperature Range page.
How do I store LiTime Xtra Mini LiFePO4 lithium batteries?
For optimal longevity, store your LiFePO4 batteries under the following conditions:
Storage Recommendations
- State of Charge (SOC): Store batteries at a 50% state of charge. Avoid storing them fully charged or completely discharged.
- Regular Recharging: If storing for an extended period, recharge the batteries to 50% at least every three months to prevent deep discharge and maintain cell balance.
- Temperature: The ideal storage temperature is between -10°C to 50°C / 14°F to 122°F.
- Humidity: Maintain a relative humidity of 45% to 75%.
- Protective Casing: It is highly recommended to store the batteries in a dedicated battery box to protect them from physical damage, dust, and moisture.
Best Practices for Long-Term Storage
For storage exceeding three months, adhering to these guidelines will significantly preserve your battery's health and performance:
- Disconnect Completely: Ensure the batteries are disconnected from all loads and charging sources. This prevents slow parasitic drains that can lead to over-discharge.
- Avoid Extreme Temperatures: Storing batteries outside the recommended temperature range can accelerate degradation. In particular, high heat can permanently damage the battery's capacity.
- Cycle Before Use: After a long storage period, it's good practice to cycle the battery (one full charge and discharge) before putting it back into regular service.

I replaced two LiTime group 31 batteries with two xtra mini 100 AH batteries. I was not sure if they could power the trolling motor the same. But so far so good. Bought me tons of space in the bow of my boat as now the two batteries fit in a battery compartment for one group 31 battery. Outstanding
j
Works as expected. As do my other 4 Litime batteries. The Xtra Mini fit in the space I had available with some room to spare.
B
What a battery. Super compact tons of power. Wasn’t available in Canada only had 50ah in the xtra mini.
R
Surprised how small the battery is definitely will be replacing the rest of my old ones
R
Plug and play, I use 20 amp charger. Works as expected. Bluetooth app on my android is easy and tells me everything except individual cell voltage. I have many different Litime batteries and they work great. Even in the cold with built-in heaters for freezingtemperatures .
C
Took the boat out today and tried the livescope battery for the first time. I spent 4 hours on livescope with the126SV screen and only used 10%. I was very impressed with how this battery performed today.
J
Nice battery small lightweight easy Store wish it would last a little longer
D
It has been working great! No issues. I like the small form factor. Easy to use and move around.
