At UpFix, we specialize in diagnosing and repairing LiFePO₄ (lithium-iron-phosphate) batteries and their BMS (Battery Management System). From batteries that won’t accept a charge or read 0 V, to BMS firmware updates and wiring faults, our certified technicians pinpoint the root cause and restore full performance—often for up to 80% less than a replacement.
