Portable Battery Design: WattCycle 12V 12Ah LiFePO4 battery is smaller (L152 x W99 x H99mm) and lighter (1.40kg) than a traditional 12V 12Ah lead-acid battery (AGM battery). Its energy density reaches 109.71Wh/kg, while the 12V 12Ah lead-acid battery (AGM battery) achieves only 18.46Wh/kg.

EV-Grade A+ LiFePO4 Cells: WattCycle 12V 12Ah LiFePO4 battery is equipped with high-quality EV-grade A+ cells, guaranteeing a lifespan of over 5000+ cycles and up to 10 years. Compared to lead-acid batteries, WattCycle LiFePO4 batteries are non-toxic, eco-friendly, and offer higher chemical stability, ensuring quality and safety.

Comprehensive BMS Protection: WattCycle 12V 12Ah lithium battery features a 12A battery management system (BMS) that provides protection against over-voltage, over-current, deep discharge, short circuits, overcharging, and extreme temperatures (high/low). It also enables cell balancing.

Up to 2457Wh Energy Solution: WattCycle 12V deep cycle LiFePO4 batteries support up to 4 in series and 4 in parallel configurations. Using the 16 12V 12Ah lithium batteries, a 48V 48Ah battery system can be built, delivering a continuous charge/discharge current of 48A, massive energy storage of 2457Wh, and an output power of 2457W.

Versatile Applications: Ideal for small devices such as fish finders, electric fishing reels, fishing gear, camping equipment, amateur radio equipment, and motorized toy cars.
