EMP rebuilds JETECH lithium-ion e-bike batteries by replacing the internal battery cells while keeping the original factory case, BMS, connector system, and mounting design when possible.

If your JETECH battery no longer holds a charge, loses range quickly, shuts off under load, or will not power on, our team can perform a full diagnostic and rebuild the pack using premium Grade-A lithium-ion cells from trusted manufacturers such as Samsung, LG, Panasonic, or Molicel.

Many JETECH batteries use generic OEM cells from the factory. During a rebuild, EMP replaces the aging internal cell pack with higher-quality cells designed for improved reliability, better capacity retention, and longer service life.

Our JETECH battery rebuild service includes complete cell replacement, internal inspection, balance testing, BMS inspection, capacity testing, and a final safety check before the battery is returned.
