ICLEBO Free 14.4V Replacement Battery YBR-B02-1 2600mAh

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

This 14.4V, 2600mAh Li-ion battery replaces the original pack in the ICLEBO Free, Plus, Pro, and Robot Pro YCR-M04-02-R robotic vacuum cleaners. It fits the same battery bay and connects through the same OEM-spec connector and BMS interface. When the original cell degrades and the vacuum starts cutting cycles short or refusing to dock-charge, this is the direct swap.

• Free, Plus, and Pro platform compatibility: These models share the same 14.4V battery architecture, connector pinout, and BMS handshake protocol — which is why one cell covers the full range. Swapping between these models on the same dock works because the charge circuit reads the same BMS signature.
• Bench tested on actual hardware: We cycled this cell through the ICLEBO charging dock and confirmed the BMS handshake cleared correctly, the protection circuit tripped at the expected overcurrent threshold, and charge termination cut off at full capacity without float-charge continuation.
• Dock charging habit for this vacuum: The ICLEBO Free auto-returns to its dock after every run. That convenience accelerates capacity fade if you leave the unit docked indefinitely between uses. Once the charge cycle completes, pull it off the dock — continuous trickle charge degrades lithium cells faster than any other use pattern on this platform.

Suction dropping before the battery indicator reaches low

The ICLEBO's motor draws significantly more current when the filter is partially blocked or the brush roll has resistance from debris. That elevated draw causes voltage to sag under load even when the cell still shows charge — the BMS reads the sag as near-depletion and throttles motor power. The indicator is measuring resting voltage, not load voltage, so the two don't match. Clean the filter and brush roll before assuming the new battery is at fault.

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

This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, jammed brush, or a dense carpet fibre catch — the motor pulls past the BMS current limit and the protection circuit disconnects the output. The pause resets the trip latch, which is why the vacuum appears to "recover." The fix is clearing the restriction, not recharging. If the cutout happens on a clean filter, check that the replacement cell's BMS trip threshold matches the OEM spec — verify the part number matches YBR-B02-1 or YCR-B01-3.
