The right battery makes or breaks an electric bike’s performance. ChamRider covers the three voltage tiers that matter most: 36V for standard assist systems, 48V for mid-drive motors, and 52V for those chasing top-end speed without cutting into range. All packs use Samsung lithium-ion cells with an integrated BMS for cell-level protection.
ChamRider has been engineering lithium-ion battery packs for electric bikes for over fifteen years. The product line spans 36 V, 48 V, and 52 V configurations, covering the full range of popular hub motors and mid-drive kits — Bafang, Tongsheng, and comparable 250 W to 750 W systems. Each pack ships after individual cell-level voltage testing, ensuring consistent capacity and balanced internal resistance across the entire batch.
Three technical pillars define ChamRider batteries: high-density cells (21700 or 18650 format), a multi-layer BMS that enforces overcurrent, overvoltage, undervoltage, and thermal limits in real time, and CE certification compliant with European e-bike regulations capping assisted speed at 25 km/h and motor output at 250 W. The BMS communicates with Bafang displays via standard UART, giving riders live state-of-charge and temperature data during every ride.
ChamRider backs every pack with a two-year warranty and an in-house repair service — cell replacement, BMS swap, or full diagnostic under load. This repairability focus means a pack that has lost 20 % capacity after four years does not have to become landfill; targeted cell replacement restores it to near-original performance at a fraction of replacement cost. Technical support is available in English, French, and German for both end users and workshop mechanics.
The use of lithium-ion cells gives these batteries high energy density, reduced weight, and extended lifespan.
