Mamibot ProVac Plus 2 Replacement Battery 7.4V 2600mAh

Mamibot ProVac Plus 2 — 7.4V Li-ion Replacement Battery (190612)

This 7.4V 2600mAh Li-ion battery replaces OEM part 190612 in the Mamibot ProVac Plus 2 robotic vacuum cleaner. It fits the main battery bay directly and supplies the voltage rail the drive motors and suction unit require. Capacity is 19.24Wh — identical to the original cell specification.

• ProVac Plus 2 fitment: The ProVac Plus 2 uses a single-cell 7.4V pack with a specific connector and BMS handshake that controls charge acceptance and low-voltage cutoff. This replacement matches that configuration — voltage, connector orientation, and BMS communication all align with the original unit.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a ProVac Plus 2 chassis. The BMS accepted charge from the OEM dock without fault codes and held cutoff voltage within spec under sustained motor load.
• Dock charging protocol for the ProVac Plus 2: Do not leave the ProVac Plus 2 sitting on the dock permanently. Continuous trickle charging compresses cell capacity significantly faster than charge-when-depleted use. Charge to full, then lift the unit off the dock until the next clean cycle.

Suction dropping before the battery indicator reaches low on the ProVac Plus 2

The ProVac Plus 2 motor draws more current when airflow is restricted — a partially blocked filter forces the suction unit to work harder than its rated draw. This pushes the battery into voltage sag territory before the indicator registers low. The BMS reads this as normal discharge and does not flag it. Clean or replace the filter first — if suction recovers, the battery was not the fault. If suction remains weak with a clean filter on a new cell, check the impeller housing for debris.

ProVac Plus 2 motor cuts out mid-clean and then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When the suction path is blocked — filter clogged, brush roll jammed, or intake obstructed — motor current spikes above the BMS protection threshold and the pack shuts down briefly. Clearing the blockage and pressing the power button restarts the unit. If the cutout recurs on a clean filter with a fully charged pack sitting at 8.2–8.4V off the charger, the original BMS has degraded and the replacement cell will resolve it.
