SUTENAI DCH-Series Hidden In-Frame Folding E-Bike Lithium Battery Pack –

 DCH-003 / DCH-006 / DCH-009 Form Factors (36V, 48V & 52V Options) for 350W–1000W Motors (Includes Integrated Smart BMS & Key Lock)

Restore or upgrade the range of your foldable electric bicycle with the SUTENAI DCH-Series Concealed Lithium-Ion Battery Pack.

Designed specifically to slide directly inside the main frame tubing of popular folding e-bikes (including Lectric XP, ENGWE EP-2 Pro, Samebike, Mate X, and CMACEWHEEL), the DCH series protects your power source from weather, debris, and theft while preserving a clean frame geometry.

Available in three standard casing dimensions (DCH-003, DCH-006, and DCH-009), this series covers 36V, 48V, and 52V nominal system voltages with energy capacities from 10Ah up to 17Ah.

Each pack features a high-current Smart Battery Management System (BMS), a heavy-duty aluminum housing, an anti-theft key locking switch, and a fold-out handle for effortless battery removal.

⚠️ Dimensions & Voltage Compatibility Notice
