Dreame Z10 Replacement Battery 25.2V 2500mAh Li-ion

Dreame Z10 / Z10 Station — 25.2V Li-ion Replacement Battery (V2308-7S1P-BCA)

This is a 25.2V, 2500mAh Li-ion replacement battery for the Dreame Z10 and Z10 Station cordless stick vacuum. It slots into the same bay as the original pack and restores power to the motor and cleaning system. Part number V2308-7S1P-BCA matches the OEM specification for this platform.

• Z10 and Z10 Station compatibility: Both models run the same 25.2V seven-cell series configuration and share an identical battery bay, connector pinout, and BMS handshake protocol — one pack covers both units without modification.
• Bench tested on actual hardware: We cycled this pack through repeated motor-load draws on the Z10 platform. The BMS held stable cutoff thresholds across suction modes, and the charger handshake completed without fault codes at every test cycle.
• Dock charging habit on the Z10: Do not leave the Z10 sitting on the charging dock permanently. Continuous trickle charge accelerates capacity fade in this cell configuration. Charge to full, then remove the vacuum from the dock until the next use.

Suction dropping before the battery indicator reaches low

On the Z10, suction loss often happens well before the battery LED shows a low charge. The motor draws higher current when airflow is restricted by a clogged filter or blocked brush roll. That elevated draw causes voltage to sag under load, and the BMS reduces output to protect the cells — even though charge level is adequate. Clean or replace the filter first, then retest suction across all power modes.

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

This is a BMS overcurrent trip, not a dead battery. When sustained airflow restriction pushes motor draw past the pack's rated discharge current, the BMS cuts power momentarily and resets. The vacuum comes back because the BMS self-recovers once current drops. Check the filter and ensure the brush roll is clear of hair wrap. If the cutout stops after clearing the blockage, the pack is functioning correctly — the trip was protective, not a fault.
