Portable Battery Design: The WattCycle 12V 20Ah lithium-ion battery is smaller (L185 x W84 x H154mm) and lighter (2.05kg) than a conventional 12V 20Ah lead-acid battery (AGM battery). Its energy density is 124.88Wh/kg, while the 12V 20Ah lead-acid battery (AGM battery) only achieves 21.58Wh/kg.

EV-Grade A+ LiFePO4 Cells: The WattCycle 12V 20Ah lithium-ion battery is equipped with high-quality EV-grade A+ cells, ensuring a lifespan of over 5000+ cycles and up to 10 years. Compared to lead-acid batteries, WattCycle LiFePO4 batteries are non-toxic, environmentally friendly, offer higher chemical stability, and ensure both quality and safety.

Comprehensive 20A BMS Protection: The WattCycle 12V 20Ah lithium-ion battery features a 20A battery management system (BMS) that protects against over-voltage, over-current, deep discharge, short circuit, overcharge, and extreme temperatures (high/low). It also enables cell balancing.

Up to 4096Wh Energy Solution: WattCycle 12V Deep Cycle LiFePO4 batteries support up to 4 in series and 4 in parallel. With the 20Ah lithium batteries, a 48V 80Ah battery system can be built, delivering continuous charge and discharge current of 80A, providing a massive energy of 4096Wh and an output power of 4096W.

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