ICLEBO Free 14.4V Replacement Battery YBR-B02-1 6800mAh

ICLEBO Free / Plus / Pro Series — 14.4V Li-ion Replacement Battery (YBR-B02-1 / YCR-B01-3)

This 14.4V, 6800mAh Li-ion battery replaces the original power cell in the ICLEBO Free, Plus, Pro, and Robot Pro YCR-M04-02-R robotic vacuum cleaners. It mounts in the same bay as the factory battery and connects through the same BMS-handshake circuit. Capacity is rated at 97.92Wh.

• Free, Plus, and Pro platform fit: These models share the same 14.4V battery bay, connector pinout, and BMS communication protocol — which is why one cell covers the full range. The control board on each unit sends the same charge-ready signal to the same pack architecture.
• Bench tested on actual hardware: We cycled this pack through repeated discharge-and-charge sequences on a robotic vacuum platform at 14.4V nominal. The BMS held cutoff thresholds correctly at both the low-voltage and overcurrent limits, with no spurious trips during motor-start draw.
• Dock charging discipline for this vacuum: Do not leave the ICLEBO on the charging dock permanently between cleaning runs. These robotic vacuums apply a continuous trickle current when docked, which accelerates cell degradation. Charge to full, then remove the unit from the dock until the next scheduled clean.

Cordless vacuum losing suction before the battery indicator reaches low

This happens when a partially blocked filter forces the motor to draw more current than its rated operating band. The extra load causes voltage to sag at the cell level while the indicator — which reads state of charge, not voltage under load — still shows a mid or high reading. The motor is starving for voltage, not charge. Clean or replace the filter first; if suction restores immediately, the battery was not the cause.

Motor cuts out mid-cycle and then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When suction is restricted — by a blocked filter, tangled brush roll, or debris jam — the motor holds a stall-like draw that exceeds the pack's continuous current limit. The BMS disconnects the output to protect the cells, then resets once current demand drops. Clear the obstruction, confirm the brush roll spins freely, and restart the unit. If trips continue with a clear path, check pack voltage under load — it should hold above 12.8V during normal operation.
