Buying Guide

What to consider when choosing an e-bike battery:

  • Voltage and compatibility: Ensure the battery’s 48V rating matches your controller and motor’s requirements.
  • Capacity and range: Higher Ah means longer range per charge, but adds weight. Choose based on typical ride distance and terrain.
  • Current protection: A BMS with adequate amp rating prevents overcharge, over-discharge, and short circuits.
  • Weight and dimensions: Check mounting space on your bike frame and how weight affects handling.
  • Weather resistance: IP65 or higher housings help with rain and dust exposure for all-season use.
  • Security features: Anti-theft locks and LED indicators add security and charging convenience.
