This 51.8V 27000mAh Li-Po battery pack is ideal for high-drain applications such as industrial drones, large-scale UAVs, robotics, electric vehicles, and high-power portable equipment where high energy density and high discharge rates are critical.

Always use a charger specifically designed for a 14S (51.8V) Lithium Polymer battery. For standard charging, use a 0.5C constant current (CC) until 58.8V is reached, then switch to constant voltage (CV) until the current drops to ≤0.05C. For faster charging, you may use a 1C or 2C current, but this may slightly reduce cycle life.

Never expose the battery to open flames, high temperatures, or puncture it. Do not disassemble or mix with other battery types. Always charge in a non-humid environment and stop using immediately if the battery shows signs of swelling, deformation, or leakage.

Under standard charge/discharge conditions (0.5C charge, 0.5C discharge) at 25℃, the battery retains ≥80% of its initial capacity after 300 cycles.

For long-term storage, keep the battery voltage between 49.2V and 50.4V (approx. 40%-50% charge) and store in a cool, dry place (0℃-35℃, ≤75% RH). Do not store at high voltage (>50.4V) for more than 7 days. Activate the battery every 3 months.

Jianheng offers a 12-month warranty from the date of shipment, provided the battery is within its cycle life and used according to specifications. Please refer to the full specification for details on warranty exclusions.

Yes. The battery is shipped at a safe voltage between 49.2V and 50.4V (40%-50% charge) in compliance with transportation regulations for lithium batteries.

Manufactured under strict quality control by Shenzhen Jianheng Technology Co., Ltd., this battery meets rigorous safety standards. It is designed with built-in protections against overcharge, over-discharge, and short circuits when used with a compatible Battery Management System (BMS).
