Services in this category

• Battery Health CheckA battery health check measures your pack's real remaining capacity and tests the cells and BMS. It tells you whether lost range means a tired battery, a bad charger, or a failing BMS.
• Battery ReplacementWhen your e-bike or scooter battery no longer holds a usable charge, a new pack restores full range and power. Replacement matches the correct voltage, capacity, and connector for your model.
• BMS (Battery Management System)The BMS protects your battery by balancing cells and cutting power on faults. When it fails, the pack may not charge, shut off randomly, or show wrong charge levels even with good cells.
• Charger Troubleshooting or ReplacementIf your battery is fine but won't charge, the charger itself may be the problem. We test the charger's output and replace it with the correct voltage and connector when it's faulty.
• Charging Port RepairIf your charger only connects at certain angles or your e-bike won't charge at all, the charging port may be loose, dirty, or burnt. Repairing the port restores a reliable charge connection.
