Xiaomi E10 Stick Vacuum Replacement Battery Z143-4S1P 14.4V

Xiaomi E10 / E10C Series — 14.4V Li-ion Replacement Battery (Z143-4S1P)

This is a 14.4V 2600mAh (37.44Wh) Li-ion replacement battery for the Xiaomi Mi E10 and E10C cordless stick vacuum. It fits the motorized brush head and suction motor circuit directly, restoring full cordless operation. Confirmed compatible across the E10, E10C, Robot Vacuum E10, and Robot Vacuum E10C platforms.

• E10 and E10C platform fit: Both the stick and robot variants in this series share the same 14.4V supply rail, Z143-4S1P connector footprint, and BMS handshake protocol — that is why one cell covers all four models without modification.
• Bench tested on actual hardware: We ran this cell through full charge-discharge cycles on an E10 unit and monitored the BMS throughout. Overcurrent protection tripped correctly under motor-start surge, and charge termination cut at the expected voltage with no anomalies.
• Dock charging habit on the E10: Do not leave the E10 sitting on the charging dock between uses. Continuous dock charge exposes the cell to sustained trickle current, which accelerates capacity fade in this battery format. Charge to full, then remove it from the dock until the next session.

Suction dropping before the battery indicator reaches low

This happens when the suction motor draws more current than rated due to a partially blocked filter or brush roll. The BMS detects the voltage sag and reduces output to protect the cell — suction weakens even though the indicator still shows charge remaining. It is not a faulty battery. Clean or replace the filter first, then clear the brush roll of any wrapped debris. If suction recovers after that, the cell is functioning correctly.

Motor cuts out mid-clean, then recovers after a few seconds

This is a BMS overcurrent trip, not a dead battery. Sustained restricted airflow forces the motor to pull excess current, and the BMS shuts the output briefly to prevent cell damage before resetting automatically. The cycle repeats as long as the restriction remains. Check the filter and inlet for blockage — clear them and the cutout stops. If it continues on a clean filter, verify the brush head is not seized, as a jammed roll produces the same overcurrent signature.
