Powerful 12.8V 315Ah lithium battery - designed for maximum self-sufficiency.

This battery is developed for users who pursue reliability, safety and maximum capacity in the smallest space. With a small size of 355*300*158mm and up to 310Ah of available power (nearly 4kWh), it is an ideal choice for RVs, boats, solar backup systems, transportation applications or 4WD off-grid camping.

High discharge and protection capabilities

Continuous 260A discharge, providing 520A burst current for 3 seconds, meeting the high-demand loads such as inverters, winches or starting surges, and adapting to a variety of complex environments.

Metal shell

The metal shell is a high-performance, environmentally friendly and safe choice. Its excellent thermal conductivity can effectively dissipate heat to ensure safety. Its natural electromagnetic shielding and corrosion resistance make the system more reliable and durable, and IP67 is shock-resistant and waterproof.

Support series and parallel connection – 12/24/36/48 V

The BMS integrates series and parallel modules, allowing the battery to be safely combined in series and parallel (up to 4 modules in each direction), suitable for various systems such as RVs, boats, golf carts, off-road vehicles, AMP lighting control systems, etc.

Smart BMS and Bluetooth APP real-time monitoring

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

Low temperature self-heating

Equipped with high-quality heating film inside, evenly distributed and controlled by BMS, it can keep the device running at temperatures as low as -20°C, especially suitable for winter camping or outdoor activities in sub-zero temperatures.

Perfect lead-acid battery replacement

Compared to AGM or lead gel batteries, this lithium battery is lighter and charges faster, and is easy to replace without modifying the equipment. In addition, it does not require continuous maintenance and has excellent stability even under extreme loads. There is no memory effect and no need for full charge and discharge cycles, which can directly replace lead-acid batteries.
