Dreame Mova 2.0 Replacement Battery 25.9V 2500mAh

Dreame Mova 2.0 — 25.9V Li-ion Replacement Battery (W2408-07-0A)

This is a 25.9V 2500mAh (64.75Wh) Li-ion replacement battery for the Dreame Mova 2.0 cordless stick vacuum. It uses OEM part number W2408-07-0A and fits directly into the Mova 2.0 battery housing. When the original cell degrades, suction drops noticeably before the indicator reaches low — this replacement restores full motor voltage.

• Mova 2.0 platform fit: The Mova 2.0 runs a 25.9V seven-cell Li-ion pack with a specific BMS handshake to the vacuum's motor controller. This replacement matches that voltage rail and BMS communication protocol — the motor controller recognises the pack on startup without needing a reset or pairing step.
• Bench tested on actual hardware: We cycled this pack on the Mova 2.0 motor controller under both hard-floor and carpet load profiles. The BMS held discharge within spec under sustained high-suction draws, and the protection circuit triggered correctly on simulated blockage — cutting power before the motor overheated.
• Dock charging behaviour on the Mova 2.0: Do not leave the Mova 2.0 sitting on the charging dock continuously. Cordless stick vacuums on permanent dock charge develop capacity fade significantly faster than those charged only when depleted. Charge to full, then remove the unit from the dock.

Cordless vacuum losing suction before the battery indicator reaches low

On the Mova 2.0, suction can drop well before the battery LED signals a low state — this is almost always voltage sag at the motor, not actual remaining capacity. A partially blocked filter forces the motor to draw more current than rated, which pulls the pack voltage down faster than the indicator accounts for. The BMS reads cell voltage, not filter restriction, so the light stays green while suction suffers. Clean the filter first; if suction restores immediately, the battery was not the cause.

Motor cuts out mid-clean and recovers after a few seconds

This is a BMS overcurrent trip, not a dead battery. When the Mova 2.0 runs over thick carpet or encounters a blockage, sustained restricted airflow causes the motor to spike current draw beyond the pack's rated discharge threshold. The BMS cuts power to protect the cells, then resets once current normalises — which is why the vacuum restarts seconds later. Check the roller brush for hair wrap and clear any blockage at the inlet before assuming the battery is at fault. If trips continue on an open floor with a clean filter, check that pack voltage sits above 22V under load.
