Mellerware City Move 14.4V Replacement Battery ES0480550L 3350mAh

Mellerware City Move / City Lite — 14.4V Li-ion Replacement Battery (ES0480550L)

This is a 14.4V 3350mAh Li-ion replacement battery for the Mellerware City Move, City Lite, TIDY RANDOM, and TIDY GYRO cordless vacuum cleaners. It replaces OEM part ES0480550L. Fit these models before ordering — connector orientation and BMS handshake requirements vary across Mellerware's vacuum range.

• City Move, City Lite, TIDY RANDOM, TIDY GYRO compatibility: These four models share the same 14.4V battery rail, connector format, and BMS communication protocol. The cell pack dimensions — 69.70 × 37.60 × 37.10mm — match the battery bay across all four without modification.
• Bench tested on actual hardware: We cycled this battery through full discharge and charge sequences on the City Move platform. The BMS correctly flagged overcurrent events during simulated filter-blocked motor load and recovered cleanly on each reset.
• Dock charging habit on these vacuums: Do not leave the City Move or City Lite sitting on the charging dock continuously. These vacuums lack active dock charge management — the cell pack sees trickle current indefinitely, which accelerates capacity fade. Charge to full, then remove from the dock.

Suction dropping before the battery indicator reaches low

The City Move motor draws harder when airflow is restricted — a partially blocked filter or blocked nozzle raises current draw above the BMS's sustained threshold. The BMS responds by stepping down power delivery before the voltage indicator registers low. The result feels like a weak battery, but the cell pack is fine. Clean the filter first, then retest under normal load.

Motor cutting out mid-clean and then recovering after a pause

This is a BMS overcurrent trip, not a failed cell. Sustained restricted airflow — usually a clogged filter or blocked brush roll — pushes motor current past the BMS cutoff threshold. The BMS shuts output, the motor stops, and after a short thermal settle the BMS resets. Remove the filter, check the nozzle for debris, and confirm the brush roll spins freely. If the fault clears after cleaning those three points, the battery is not the cause.
