KEPAH Hailong High-Capacity Lithium E-Bike Battery Pack –

36V / 48V / 52V Options, 20Ah & 30Ah Capacities with Integrated BMS (Optimized for Bafang BBS02, BBS03, BBSHD & 750W–1000W Motors)

Upgrade your electric mountain bike, commuter rig, or custom mid-drive conversion with the KEPAH Hailong Down-Tube Lithium-Ion Battery Pack. Built into the industry-standard Hailong hardcase shell (360mm × 90mm × 110mm), this high-density battery pack provides ultra-long-range capacity for heavy-duty electric bicycles, robots, and custom e-mobility builds.

Specifically engineered to support high-draw mid-drive motors such as the Bafang BBS02, BBS03, and BBSHD (750W to 1000W+), every KEPAH pack features a heavy-duty Integrated Battery Management System (BMS). The built-in BMS actively regulates cell balancing, over-current cutoff, over-charge protection, and thermal monitoring to deliver reliable peak output under heavy off-road loads.
