Product Highlights and Key Benefits

High Energy Density For a Long Service Life: With a high capacity of 140Ah, the under-seat battery is suitable for vans, motorhomes and mini campers with a seat height of up to 190mm, for high current loads or for long periods without a mains connection.
Bluetooth 5.0 Certified: Real-time monitoring of battery status via the Power Queen APP - stable and easy (up to 10 metres).
Low Temperature Charging Protection: Automatic low temperature shutdown protection interrupts charging when the battery temperature drops below 0 °C and resumes charging when the battery has warmed up to a safe range (5 °C) to ensure safe charging in cold environments.
Built-in Intelligent BMS System: The integrated battery management system (BMS) provides comprehensive protection against overcharging, over-discharging, over-temperature, over-current and short-circuiting, extending the battery's service life and ensuring user safety. After an interruption, it can automatically resume operation without human intervention.
Supports Flexible Extension of Multiple Batteries: Supports up to 4 batteries in series (48V system) and 4 batteries in parallel, which can form a maximum energy storage system of 28.67kWh to meet home, commercial or automotive energy storage needs.
Multi-scenario Customisation, Stable As One

Whether users are exploring faraway places in a caravan, experiencing the natural life in an off-grid cabin or looking for a stable battery for their home energy storage system, the 12V 140Ah 190H Li-FePO4 battery will be the trusted power core.
