Media BP2522A 25.2V Replacement Battery P6 SNOW Vacuum 2000mAh

Midea P6 SNOW / P91 BLUE Series — 25.2V Li-ion Replacement Battery (BP2522A)

This is a 25.2V, 2000mAh (50.4Wh) lithium-ion battery replacing OEM part BP2522A. It fits the Midea P6 SNOW, P91 BLUE, P6, and P6 MASTER cordless stick vacuums. Swap it when the original battery no longer holds charge or the vacuum cuts out before the task is done.

• P6 and P91 BLUE platform compatibility: These models share a common 25.2V battery rail and the same physical connector and BMS handshake protocol. One cell pack covers the full listed range — no adapters or firmware differences between variants.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a P6 SNOW unit. The BMS communicated correctly with the charger, held voltage under sustained motor load, and triggered protection cutoff cleanly at the low-cell threshold without nuisance trips.
• Dock charging habit on the P6 platform: Do not leave the vacuum sitting on the charging dock permanently. Continuous trickle charge degrades cell capacity faster than normal cycling. Charge to full, then remove from the dock until the next use.

Cordless vacuum losing suction before the battery indicator reaches low

This is one of the most common complaints on the P6 platform, and it is rarely a battery fault by itself. A partially blocked filter forces the motor to draw more current than rated to maintain airflow. That higher draw causes voltage to sag at the cell level before the indicator registers a low state. Clean the filter first — if suction recovers and the indicator stabilises, the battery was reacting normally to a restricted load, not failing.

Motor cuts out mid-run then recovers after a short pause

This behaviour is a BMS overcurrent trip, not a dead battery. On the P6, sustained restricted airflow — usually a clogged filter or a blockage in the nozzle — forces the motor into a high-draw state that exceeds the BMS current limit. The BMS shuts the output to protect the cells, then resets once temperature drops. Clear the blockage and check that the filter is fully dry before reinstalling. If the trips continue on an unblocked vacuum with a clean filter, test cell voltage at rest — it should read above 24V for a charged pack.
