Media BP2160J Replacement Battery 21.6V 2000mAh V1 Pro

Midea V1 Pro / P3 MULTI — 21.6V Li-ion Replacement Battery (BP2160J)

This is a 21.6V 2000mAh Li-ion replacement battery for the Midea V1 Pro and P3 MULTI cordless stick vacuums. It replaces OEM part BP2160J directly. Fit this battery when the original no longer holds charge or suction time has noticeably shortened.

• V1 Pro and P3 MULTI compatibility: Both models run the same 21.6V rail and use an identical BP2160J battery pack with the same connector and BMS handshake. One battery fits either unit with no wiring changes.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the V1 Pro motor platform. The BMS responded correctly to current draw under simulated floor and carpet loads, and the protection circuit tripped cleanly under overcurrent — no thermal events observed.
• Dock charging practice for this vacuum: Do not leave the V1 Pro sitting on the charging dock permanently. Cordless vacuums on continuous dock charge develop capacity fade faster than those charged only when depleted. Charge to full, then remove from the dock.

Suction dropping before the battery indicator reaches low

This happens when motor voltage sags under load before the cell is actually depleted. On the V1 Pro, a partially blocked filter forces the motor to draw more current than rated, and the BMS may throttle output to protect the cell. The battery indicator tracks voltage, not current draw — so it still reads mid-range while suction has already dropped. Clean or replace the filter first, then retest under the same load.

Motor cutting out mid-clean and then recovering after a few seconds

This is a BMS overcurrent trip, not a dead battery. When airflow is restricted — blocked nozzle, full dust cup, or clogged filter — the motor works harder and current spikes past the BMS threshold. The BMS cuts power to protect the cell, then resets once current drops. The fix is not a new battery — clear the blockage, empty the dust cup, and check the filter. If cut-outs continue with clean airflow, measure pack voltage under load; a healthy cell should hold above 18V at the motor terminals during normal suction.
