Levoit LVAC-200 Replacement Battery 22.2V 2500mAh

Levoit LVAC-200 Cordless Stick Vacuum — 22.2V Li-ion Replacement Battery (LSV-V201B-WUS)

This 22.2V 2500mAh (55.5Wh) lithium-ion battery replaces the original pack in the Levoit LVAC-200 cordless stick vacuum. It fits the LVAC-200 directly using the OEM part number LSV-V201B-WUS. The battery powers both the motor and brush roll across hard floors and carpets.

• LVAC-200 platform fit: The LVAC-200 uses a 22.2V six-cell Li-ion pack with a BMS that monitors cell voltage and current draw from the motor and brush roll. Replacement packs must match this voltage rail and carry the correct BMS handshake — mismatched packs will not initialise and the vacuum will not power on.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the LVAC-200 motor platform. The BMS managed overcurrent events during simulated heavy carpet load without false tripping, and cell voltage stayed balanced across all six cells at end of discharge.
• Dock charging habit on the LVAC-200: Do not leave the LVAC-200 sitting on the charging dock permanently. Continuous trickle charge after a full cell causes capacity fade faster than normal cycle wear. Charge to full, remove from the dock, and return it only when the battery is depleted.

Suction dropping before the battery indicator reaches low

The LVAC-200 motor draws significantly more current when the filter is partially blocked or the brush roll is restricted. That elevated current draw causes voltage to sag under load even when cells still hold charge at rest. The BMS reads the sag as a low-power condition and throttles motor output — which shows up as weak suction well before the indicator warns you. Clean or replace the filter first. If suction recovers, the battery is not the fault.

Motor cutting out briefly then recovering mid-clean

This is a BMS overcurrent trip, not a dead battery. When sustained suction restriction forces the motor to pull beyond the pack's rated current ceiling, the BMS disconnects the output to protect the cells — then resets after a few seconds. It will keep happening if the restriction remains. Check the filter, the brush roll for hair wrap, and the inlet for blockage. Clear the restriction and the BMS will stop tripping; resting cell voltage should read above 20V if the pack itself is healthy.
