Belicore Aluminum Hidden Foldable E-Bike Battery Case Enclosure (DCH006 / ALX009 Series) – Replacement Housing for 36V, 48V & 52V 18650 Lithium Battery Builds

Restore or upgrade the internal power core of your folding city e-bike with the Belicore DCH006 / ALX009 Series Hidden Battery Box. Engineered to slide directly inside the main frame tube of popular folding e-bikes, this lightweight aluminum alloy case provides stealthy, internal battery protection without sacrificing the compact footprint of your foldable bike.

Constructed from extruded, high-grade aluminum alloy paired with durable ABS end caps, base plug, and ALX head cover, this housing shields your 18650 lithium-ion cell matrix against frame flex, trail vibration, moisture, and road impacts. Available in three standard vertical lengths (410mm, 420mm, and 430mm), it allows DIY builders and repair technicians to build custom 36V, 48V, or 52V battery packs with clean OEM-style fitment.

⚠️ Important Fitment & Sizing Notice

Before Purchasing: This listing is for an empty replacement battery housing with head cover and base plug (battery cells, BMS, nickel strips, and internal wiring are not included).
