RobZone Robee Plus 14.4V Replacement Battery 2000mAh Ni-MH

RobZone Robee Plus — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2000mAh Ni-MH replacement battery for the RobZone Robee Plus robotic vacuum cleaner. It powers the motor, brush system, and navigation electronics. Fits the Robee Plus directly — verify your model before ordering.

• Robee Plus motor and drive system: The Robee Plus runs its suction motor and wheel drive off the same 14.4V rail. A degraded cell causes voltage sag under load — the motor slows before the battery indicator reads low. This cell matches the original voltage and capacity spec to keep that from happening.
• Bench tested on actual hardware: We cycled this battery through repeated charge and load discharge sequences. The BMS held within expected cutoff thresholds and the pack recovered cleanly from deep discharge without requiring a manual reset.
• Dock charging behaviour on Ni-MH: Do not leave the Robee Plus sitting on the charging dock indefinitely. Ni-MH cells are sensitive to continuous trickle charge — charging to full and removing the unit from the dock prevents accelerated capacity fade over time.

Suction dropping before the battery indicator reaches low

This happens when cell voltage sags under motor load before the battery is actually depleted. A clogged filter forces the motor to draw more current than rated, which drops cell voltage faster and triggers the BMS to reduce output. The result looks like a weak battery even on a fresh charge. Clean the filter first — if suction recovers, the battery is fine. If the pack is genuinely degraded, resting cell voltage under no load should read above 13.5V on a full charge.

Motor cuts out mid-cycle and then recovers on its own

This is a BMS overcurrent trip, not a battery failure. When suction is restricted — blocked brush roll, clogged filter, or hair wrap — the motor strains and draws a sustained current spike. The BMS cuts the circuit to protect the cells, then resets once current drops. Clear the obstruction and restart the unit. If the trip keeps happening on a clear brush with a new battery, the motor itself may be drawing above spec and needs inspection.
