Proscenic LDS M7 Replacement Battery 14.4V 2600mAh

Proscenic LDS M7 / M6 Pro — 14.4V Li-ion Replacement Battery (MH1-4S1P-SC)

This is a 14.4V 2600mAh Li-ion battery for the Proscenic LDS M7 and M6 Pro robot vacuum. It replaces part number MH1-4S1P-SC and slots into the battery bay on both models. Capacity figure is taken from the product specification — 37.44Wh total energy.

• LDS M7 and M6 Pro shared platform: Both models run the same 14.4V battery rail, the same bay footprint, and the same BMS handshake protocol. One cell pack covers both. The 4S1P cell configuration matches the original charge and discharge profile the onboard controller expects.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on an LDS M7 unit. The BMS communicated correctly with the robot's charge circuit, accepted a full charge without fault codes, and discharged across a representative cleaning cycle without tripping overcurrent protection.
• Dock charging habit on the LDS M7: The LDS M7 is frequently left on its dock between uses. Continuous trickle charging accelerates capacity fade in Li-ion cells. Charge the robot to full, then lift it off the dock — return it to the dock only when the battery needs charging again.

Suction dropping before the battery indicator reaches low

The LDS M7 motor is the single largest current draw in the system. When the filter is partially blocked, airflow restriction forces the motor to pull harder to maintain suction — current demand spikes above the BMS discharge threshold and the cell voltage sags under load. The robot reads this voltage sag as low battery and reduces motor power, even though cell charge state is still high. Clean or replace the filter first; if suction recovers immediately, the battery was not the fault.

Robot cuts out mid-clean and then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. Sustained restricted suction — usually a clogged filter or a partial blockage at the brush roll — drives current above the pack's protection threshold. The BMS disconnects to protect the cells, the robot stops, and the circuit resets after a short thermal or timer-based recovery window. Clear any blockage at the brush roll and check the filter condition. If the cutout stops after clearing the blockage, the pack is functioning correctly — the BMS tripped as intended.
