Aleaivy DCH-009 Upgraded 48V / 52V Folding E-Bike Replacement Battery (13Ah / 15Ah / 17.5Ah | Engwe EP-2 Pro, Engine X/Pro & MATE X Compatible)

Revitalize your folding fat-tire e-bike with the Aleaivy DCH-009 High-Capacity Replacement Battery Pack. Purpose-built for internal frame integration, this DCH-009 battery is a direct drop-in replacement or backup battery for popular folding e-bikes, including the Engwe EP-2 Pro, Engwe Engine X, Engwe Engine Pro (16Ah version), MATE X, CMACEWHEEL RX20, Bezior XF200 / X Plus, and Ginghma R7 Pro. Standardized at $420 \times 115 \times 58\text{ mm}$, this pack features high-density lithium-ion cells in a durable aluminum casing and is available in 48V and 52V configurations with capacities up to 17.5Ah ($840\text{Wh} - 910\text{Wh}$).

⚠️ Important Fitment Notice & Safety Guidelines

CRITICAL FITMENT INFORMATION (DCH-009 vs. DCH-006):

  • Check Your Battery Dimensions Before Ordering: Newer model Engwe and Bezior e-bikes utilize the DCH-009 battery ($58\times114\times418\text{ mm}$ / $420\times115\times58\text{ mm}$ outer profile). Older production runs used the thinner DCH-006 battery ($43\times103\times430\text{ mm}$). Please verify your original pack's dimensions to ensure correct frame fit.

  • Internal Frame Slide-In Form Factor: Precision-machined aluminum body slides directly inside the bike's main folding frame tube.

  • 52V Upgrade Option: Choose the 52V configuration for improved throttle response, greater hill-climbing torque, and reduced voltage sag under high motor loads.

  • CE Certified BMS Protection: Equipped with an internal Battery Management System that continuously guards against over-charging, over-discharging, short circuits, and thermal runaway.

🚀 Key High-Performance Features

  • Expanded Range Options (13Ah, 15Ah, 17.5Ah): Delivers up to $910\text{Wh}$ of energy storage to power longer commutes, off-road expeditions, and daily urban riding.

  • Integrated Folding Extraction Handle: Features a heavy-duty top handle for quick, hassle-free removal from the bike's frame tube for off-bike charging.

  • Mechanical Security Key Lock: Locks the battery safely inside the frame structure to prevent theft and keep the battery firmly connected during rough trail riding.

  • External Charge Port & Power Switch: Charge the battery directly while installed inside the bike frame, or remove it for desktop charging at home or in the office.

  • Durable Heat-Dissipating Alloy Casing: Rugged aluminum shell protects internal lithium cells against impact, trail vibrations, and heat buildup.
