ICLEBO Omega YCR-MT12-S1 Replacement Battery 14.52V 5200mAh

ICLEBO Omega Series — 14.52V Li-ion Replacement Battery (YCR-MT12-S1)

This is a 14.52V, 5200mAh (75.5Wh) lithium-ion replacement battery for the ICLEBO Omega robotic vacuum cleaner. It also fits the O5, XIC013, and YCR-M07-20W models that share the same voltage rail and connector format. Swap it in when the original cell no longer holds enough charge to complete a full cleaning cycle.

• Omega, O5, XIC013 and YCR-M07-20W compatibility: These models run the same 14.52V battery platform with an identical BMS handshake and connector pinout. One replacement covers all four without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Omega platform. The BMS accepted the pack without fault codes, held voltage within spec under motor load, and tripped correctly at the low-voltage cutoff threshold.
• Dock charging habit for this model: Do not leave the Omega sitting on its dock indefinitely after a full charge is reached. Continuous trickle charging on this platform accelerates capacity fade. Charge to full, then remove the robot from the dock until the next cleaning run.

Suction dropping before the battery indicator reaches low

A partially blocked filter forces the Omega's motor to draw more current than its rated load. The BMS reads this elevated draw as a voltage sag event and begins throttling power to the motor before the battery is actually depleted. The battery indicator can still show two or three bars while suction has already dropped noticeably. Clean or replace the filter first — if suction recovers immediately, the battery was not the cause.

Motor cutting out mid-cycle and then recovering after a few seconds

This is a BMS overcurrent trip, not a dead battery. When the Omega's intake is restricted — blocked brush roll, clogged filter, or dense carpet pile — sustained high current draw pushes past the BMS protection threshold and it cuts the output. The pack resets after a brief cool-down period, which is why the motor restarts on its own. Clear the restriction, then confirm pack voltage reads at or above 14.0V before the next run.
