Product Overview
The 25.6V 100Ah Low Temperature LiFePO4 Battery is a deep-cycle lithium battery designed for reliable charging and discharging in cold conditions.
It features a BMS heating film that enables safe charging when ambient temperatures are below freezing.
When the temperature is below 32°F (0°C) and charging is connected, the heating film turns on. The charger supplies power to the heating film and does not charge the battery below 0°C. Once the battery reaches 50°F (10°C), the BMS stops heating and normal charging begins. During storage and discharge, the heating film does not work and does not consume battery power.
With 25.6V nominal voltage, 100Ah capacity and 2560Wh energy, this lightweight LiFePO4 battery is designed as a maintenance-free replacement for traditional
lead-acid batteries in 24V systems. It is suitable for solar and wind energy storage, UPS/EPS backup, RVs, caravans, motor homes, marine boats, telecom systems,
DC power supply and auto control systems.
Key Benefits
Cold-weather charging protection – BMS heating film enables safe charging in low temperatures
No heating power drain during storage or discharge – heating only operates under charging conditions
Deep-cycle LiFePO4 chemistry – up to 5000 cycles
High energy capacity – 25.6V 100Ah, 2560Wh
Lightweight design – approx. 23.5 kg, significantly lighter than equivalent lead-acid batteries
High current performance – 100A max continuous discharge, 300A peak for 1–3s
Built-in BMS protection – over-charge, over-discharge, over-current, short circuit and temperature protection
IP65 ABS case – suitable for outdoor, marine and demanding environments
5-year warranty – factory-direct supply with OEM/ODM support
Low-Temperature Charging: How It Works
| Stage | BMS Heating Behavior |
|---|
| Below 0°C / 32°F | Heating film turns on under charging conditions; battery does not charge |
| Heating process | Charger supplies power to the heating film |
| Reaches 10°C / 50°F | BMS stops heating; battery starts charging |
| Storage / discharge | Heating film does not work and does not consume battery power |
This design makes the battery suitable for cold-climate solar storage, winter RV use, marine applications and 24V backup power systems
where charging below freezing can otherwise be unsafe.
