About this replacement
Dreame P10 / P10 Pro — 25.6V Li-ion Replacement Battery (P2125-7SIP-SCA)
This 25.6V, 2400mAh lithium-ion battery pack replaces the original power cell in the Dreame P10 and P10 Pro cordless stick vacuums. It fits the motor and BMS handshake requirements of both models and carries OEM part numbers P2125-7SIP-SCA and P2013A-7SIP-SC-02. Capacity is 61.44Wh, matching the factory specification.
- P10 and P10 Pro compatibility: Both models run the same 25.6V seven-cell series architecture and share an identical connector and BMS communication protocol, which is why one pack covers both variants without modification.
- Bench tested on actual hardware: We cycled this pack through full charge and discharge on the P10 Pro motor platform, confirmed the BMS handshake cleared correctly, and verified the cell voltage held within spec across sustained high-suction mode.
- Dock charging behaviour on the P10 series: Do not leave the vacuum sitting on the charging dock continuously. The P10 dock does not terminate charge at 100% in a way that protects long-term cell health — charge to full, then remove the unit from the dock entirely between sessions.
Suction dropping before the battery indicator reaches low
The P10 Pro's BMS monitors cell voltage under load, not at rest. When the filter is partially blocked or the brush roll is restricted, motor current draw spikes and the BMS reads a voltage sag that it interprets as low charge. The motor throttles back to protect the cells, even if the indicator still shows two or three bars. Clean the filter and check for blockages first — if suction recovers immediately, the battery is not the fault.
Motor cuts out mid-clean then recovers after a short pause
This is an overcurrent trip, not a flat battery. The P10 series BMS cuts power when sustained draw exceeds its current threshold — typically triggered by a blocked filter forcing the motor to work harder. The pack resets itself after a brief cooldown, which is why the vacuum powers back on a minute or two later. Check and wash the HEPA filter, then confirm the post-motor filter is clear before ruling out a cell fault.
