ICLEBO Free YBR-B02-1 Replacement Battery 14.4V 3400mAh

ICLEBO Free / Plus / Pro Series — 14.4V Li-ion Replacement Battery (YBR-B02-1)

This is a 14.4V, 3400mAh Li-ion battery for the ICLEBO Free, Plus, Pro, and Robot Pro YCR-M04-02-R robotic vacuum cleaners. It replaces OEM part numbers YBR-B02-1 and YCR-B01-3. When the original cell degrades, suction drops and cleaning cycles shorten — this battery restores both.

• Free, Plus, and Pro platform compatibility: These models share the same 14.4V battery rail, connector pinout, and BMS handshake protocol. One cell fits all listed variants without modification or adapter.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the ICLEBO platform. The BMS passed overcurrent protection checks and communicated correctly with the charger throughout.
• Dock charging habit for this robot: Do not leave the robot parked on the charging dock continuously. ICLEBO robotic vacuums on permanent dock contact receive a low-level trickle charge that accelerates capacity fade. Charge to full, then remove the robot from the dock until the next cleaning cycle.

Suction dropping before the battery indicator reaches low

This happens when the motor draws higher current than rated — usually caused by a partially blocked filter or brush roll restriction. Under that extra load, cell voltage sags early and the BMS throttles power to protect the pack, which the robot interprets as a low-battery condition. The indicator hasn't caught up because voltage sag is temporary, not a true state-of-charge reading. Clear the filter and brush roll first, then retest — if suction holds, the battery is fine.

Motor cutting out mid-cycle and then recovering on its own

This is an overcurrent trip, not a dead battery. When the brush roll hits heavy carpet or a blockage, current spikes past the BMS threshold and the pack shuts output to prevent cell damage. After a few seconds the BMS resets and power returns. Remove any debris from the brush roll channel, clean the filter, and run a cycle — if the cutout stops, the restriction was the cause. If it continues on a clear floor, check that the replacement cell is sitting fully seated and the connector is locked at 14.4V.
