Is your electric scooter giving very low mileage? Does your e-rickshaw pack shut off suddenly? In 85% of cases, the individual battery cells are still healthy. The issue is usually a failed Battery Management System (BMS) or cell-voltage drift (imbalance) that prevents the pack from full charging.
At ElectroAnt, we diagnose individual cell groups, swap degraded cells with matched capacities, install smart active-balancing BMS circuits, and restore your pack's original range at a small fraction of the cost of a new battery.
Book Diagnostic ScanThe battery charge indicator goes from 100% to 20% within a few kilometers. Typically caused by cell imbalance or one dead parallel string.
Charger shows green light immediately or battery rejects incoming current. Usually caused by a locked or damaged BMS protection board.
The scooter turns off completely when accelerating or climbing slopes. Occurs when a degraded cell group drops below the low-voltage cutoff point.
Internal moisture entry causing oxidation on nickel strips, short-circuits, or wire corrosion. We clean, re-weld, and re-pack safely.
We connect your battery pack to our computerized diagnostic system to measure individual cell voltages under load. This lets us pin-point the exact parallel string or module that has degraded.
Using active cell balancing systems, we charge and discharge cell strings individually to match their voltages. If any cell has failed chemically, we desolder it and replace it with a cell of matching internal resistance.
We replace cheap, standard BMS boards with intelligent Smart BMS units featuring Bluetooth monitoring. This allows you to check cell voltages, temperature, and cycles directly on your mobile phone.
The pack is re-wrapped in safety thermal barriers and housed in its outer case with fresh silicone sealant. This provides structural reinforcement and guards against Jaipur's hot summer temperatures and monsoon rains.
Exact repair costs depend on the diagnostics scan and cell counts, but here are our typical service price ranges:
*Prices exclude government GST taxes. Warranty on replaced cells/parts is 6 months.
