BATTERY
RE-CELL
Should your battery exhibit signs of wear and tear or aging, our specialized re-celling service steps in to rejuvenate its performance.

CELL
BALANCING
Over time, it is common for the voltage levels of cell groups within a battery pack to become desynchronized, leading to potential range limitations. This cell balance discrepancy may stem from gradual voltage shifts or a defective cell group, both of which are carefully assessed and addressed during the diagnostic evaluation. Our balancing services, priced starting at £70, are designed to rectify these issues, ensuring optimal performance and efficiency of your battery pack.
BMS
