Moneual MBOT 950 Replacement Battery 14.4V 3400mAh

Moneual MBOT 950 / MBOT 900 Series — 14.4V Li-ion Replacement Battery

This 14.4V 3400mAh Li-ion battery fits the Moneual MBOT 950, MBOT 900, MBOT 900i, and MBOT 500 robotic vacuum cleaners. It replaces the original pack when capacity fade cuts cleaning cycles short. Dimensions are 132.38 × 36.78 × 21.10mm — check these against your existing pack before ordering.

• MBOT 500, 900, 900i, and 950 compatibility: These four models share the same 14.4V battery bay, connector pinout, and BMS communication protocol. A single cell format covers all four platforms without modification.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge sequences on the MBOT platform. The BMS handled motor-start inrush current without tripping and maintained stable voltage delivery through the cleaning cycle.
• Dock charging discipline: Do not leave the robot parked on the charging dock continuously. Robotic vacuums on permanent dock contact trickle-charge the Li-ion cells even when full, accelerating capacity fade. Charge to full, then remove the unit from the dock between uses.

Suction dropping before the battery indicator reaches low

This happens when the motor draws more current than rated — usually because airflow is restricted by a clogged filter or partially blocked brush roll. The increased load causes voltage to sag at the pack terminals before the battery's state-of-charge actually reaches the low threshold. The robot interprets this voltage sag as low battery and reduces motor speed. Clear the filter and brush roll first — if suction recovers, the battery is not the cause.

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

This is a BMS overcurrent trip, not a dead battery. When suction is sustained against a blockage or dense carpet, current draw spikes past the BMS protection threshold and the pack disconnects. After a brief pause, the BMS resets and power returns. Check the filter — a partially blocked filter forces the motor to sustain high draw continuously. If the cutout disappears after cleaning the filter, the pack itself is functioning correctly.
