Compact 12.8V 175Ah lithium battery - designed for under the seat.

This compact 12.8V180Ah lithium battery under the seat uses automotive-grade LiFePO₄ cells, 200A high discharge + low-temperature self-heating + smart Bluetooth monitoring + dual-terminal design, simple installation, strong compatibility, and is an ideal upgrade solution for RVs such as Fiat Ducato, Citroen, Peugeot, and Volkswagen RVs.

Dual-purpose terminal design

The lithium battery adopts a copper column + M8 internal thread dual-purpose terminal design, which perfectly combines the dual advantages of high conductivity and strong compatibility: using high-quality pure copper material, excellent conductivity efficiency, low connection resistance, and easy to cope with hundreds of amperes of high current scenarios; M8 threads are compatible with standard nuts and ring terminals, and multi-line parallel connection can be achieved without adapters, making installation more flexible and efficient.

Smart BMS and Bluetooth APP control

New energy vehicles are equipped with the same level of smart BMS to protect each battery from overload, overvoltage and undervoltage.
Voltage, current, charging status, temperature, current and number of cycles can be conveniently monitored via Bluetooth on a smartphone or tablet. The APP can monitor up to 8 batteries at the same time. Ideal for marine or off-grid professionals who value remote diagnostics and status checks.

Low-temperature self-heating

High-quality internal heating film, evenly distributed and controlled by the BMS, keeps the device running at temperatures as low as -20°C, perfect for winter camping or outdoor activities in sub-zero temperatures.

Supports series-parallel connection – 12/24/36/48 V

BMS integrated series-parallel module allows batteries to be safely combined in series and parallel (up to 4 modules in each direction) for various systems such as RVs, boats, golf carts, off-road vehicles, AMP lighting control systems, etc.

Perfect lead-acid battery replacement

Compared to AGM or lead gel batteries, this lithium iron phosphate (LiFePO₄) battery is lighter (60% less) and charges faster, making it easier to use. In addition, it requires no ongoing maintenance and has excellent stability even under extreme loads, making it ideal for continuous use in marine, camping and professional applications. No memory effect, no need for full charge and discharge cycles, can directly replace lead-acid batteries.
