Reliable Power for Your Adventures
If you're looking for a reliable lithium battery to power your RV, solar system or off-grid system, this 12V 100Ah battery is a compact, lightweight option with low-temperature power-off protection, making it ideal for outdoor enthusiasts and home users. Weighing 9.2 kg and measuring 260 × 168 × 212 mm, this 12V 100Ah lithium battery allows for easy installation in confined spaces such as RV cabins or solar installations, making it an ideal alternative to bulky lead-acid batteries.
Long-Lasting Performance and Advanced Safety
This 12V 100Ah lithium battery is equipped with multiple features. It uses high-quality Grade A LiFePO4 cells, has a capacity of 1280Wh, and the case is marked 150A BMS (about 1,920W). It can withstand more than 5,000 charge cycles (at rated conditions). The BMS covers overcharge, over-discharge, overcurrent and short circuit, plus low-temperature and high-temperature protection.
Low-Temperature Protection for Cold Climates
This 12V 100Ah battery features an advanced low-temperature power-off function, ensuring stable operation even in cold environments. When the temperature drops below 0°C, the battery stops charging to prevent damage; when the temperature drops below −20°C, the battery stops discharging; and once the temperature rises above 5°C, the battery resumes charging. This intelligent design ensures safety and extends battery life, making it the preferred power source for RV camping, off-grid living, or any cold environment.
Scalable Capacity for Your Needs
If you require higher power output, this 12V 100Ah battery supports a 4S4P extended design, allowing it to be configured as a 51.2V 400Ah system (capacity up to 20.48kWh) or as a 12.8V 400Ah (5.12kWh) or 51.2V 100Ah (5.12kWh), making it flexible for use in large-scale solar or home energy systems.
Enjoy Flexible Charging Options
This 12V 100Ah battery offers three flexible charging options, and you can monitor the charging process via Bluetooth. At 0.2C (20A) a full charge takes about 5 hours. At 0.5C (50A) it reaches about 97% in about 2 hours. A generator needs a LiFePO4 AC charger. Vehicle charging uses a DC-to-DC charger.
Power a Range of Applications with Ease
This 12V 100Ah battery, with its compact size and low-temperature power-off capability, is easy to install and use in cold weather, allowing you to expand your field of vision and check battery status at any time. For RV enthusiasts, Recharge it every 3 months if it is stored. For home energy storage, it can provide longer-lasting power for household appliances, while for marine use, it can power electric propulsion systems.

Charge it
- Lithium iron phosphate 4-string charger, 14.6V.
- Solar through an MPPT. Pick 12V (14.6V) LiFePO4 mode, or user mode and type the values from the table.
- An inverter that has a built-in AC-to-DC charger, on the same lithium profile.
- 20A (0.2C) — about 5 hours to 100%
- 50A (0.5C) — about 2 hours to 97%
Voltage right off the charger is not the resting voltage. Disconnect, wait 15 minutes, then measure.

Bank wiring
Up to 4 in series (48V class) and up to 10 in parallel only. Max 4S4P combined. Same model, same brand, bought within a month, voltages matched.
Charge each battery alone, then parallel them for 12–24 hours before the final series or parallel layout. Full connection notes
Bluetooth 5.0. The manual includes app connection and monitoring instructions.
BMS
The enclosed BMS covers over-charge, deep discharge, overload, overheating, short circuit and a low self-discharge rate. It disconnects if the inside of the battery reaches 75°C. It also disconnects if a single cell goes above 3.65V or below 2.5V. Below 13.8V it will not show as full. If the BMS has opened, remove the load and rest it for 30 minutes, then fully charge. If it is too flat to accept a charge, use a charger that can start from 0V, or parallel another 12V lithium (or a lead-acid between 12V and 14.6V) for about a minute, then fully charge.
