Import 36v15ah Downtube Lithium Battery For E-Biek — Buy in wholesale FOB from Supplier in China

This 36V 15Ah downtube lithium battery is a frame-integrated power pack for electric bicycles, with a rated voltage of 36V and a nominal capacity of 15Ah. The source indicates a minimum capacity of 14.5Ah, and an overcharge detection voltage of 42.5V for cell protection. The battery is designed for mounting on the downtube of e-bike frames, a position that maintains low centre of gravity and preserves frame geometry for handling stability.

The cell chemistry is lithium-ion, standard for this voltage and capacity class in the e-bike sector. The 36V 15Ah configuration delivers approximately 540Wh of energy storage, typical for commuter and light trekking e-bikes with pedal-assist ranges of 40-80km depending on motor efficiency, terrain and rider input. Overcharge protection at 42.5V indicates a battery management system (BMS) with voltage monitoring, a standard safety requirement for lithium battery packs. The physical form factor, weight and specific cell type are not stated in the source data and should be confirmed directly with the supplier.

This battery suits e-bike manufacturers, conversion kit distributors and fleet operators seeking a downtube-format pack for 36V mid-drive or hub-motor systems. Buyers should clarify cell brand and cycle life claims, BMS functionality beyond overcharge detection, and IP rating for weather resistance. Charging port type, discharge connector standard, and mounting bracket compatibility with common frame sizes are also critical for integration. All trade terms, certification status and minimum order quantities must be confirmed with Shenzhen Believe Technology Co., Ltd.

Shenzhen Believe Technology Co., Ltd. is located at D1 Building, Guanghaofeng Industry Park, Gushu, Baoan District, Shenzhen, Guangdong Province, China.
