About this replacement
Midea F30 / F30 Station — 29.6V Li-ion Replacement Battery (BP29625C)
This is a 29.6V 2500mAh (74Wh) lithium-ion battery for the Midea F30 and F30 Station cordless stick vacuums. It replaces OEM part BP29625C. Use it to restore full suction power to a vacuum that's losing performance due to a degraded original cell pack.
- F30 and F30 Station compatibility: Both models run on the same 29.6V battery architecture and share the BP29625C connector and BMS handshake. One replacement covers either unit.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the F30 platform. The BMS correctly reported state-of-charge to the vacuum's indicator LEDs and tripped overcurrent protection under a simulated motor blockage, then reset cleanly.
- Dock charging practice on the F30: Do not leave the F30 sitting on the charging dock indefinitely. The dock does not cut trickle current after full charge the way a smart charger would. Charge to full, then remove the vacuum from the dock to slow capacity fade.
Suction dropping before the battery indicator reaches low
This is voltage sag under motor load — not an empty battery. When the cell pack ages, internal resistance rises. Under the sustained current draw of the F30 motor, terminal voltage drops enough to reduce motor speed, which cuts suction. The indicator LEDs read state-of-charge at rest, so they still show two or three bars while suction has already fallen. Replacing the pack restores the low internal resistance that keeps voltage stable through a full cleaning cycle.
Motor cuts out mid-clean and then restarts after a short pause
This is an overcurrent trip in the BMS, not a faulty motor. It almost always happens when the filter is partially blocked — restricted airflow forces the motor to spin harder and draw more current than the BMS allows. The BMS cuts the circuit to protect the cells, then resets once current demand drops. Clean or replace the filter first. If the cutouts continue with a clean filter and a fresh battery, check that the brush roll is not jammed, as that causes the same sustained overcurrent condition.
