Laresar Grande 2 Replacement Battery 14.4V 2600mAh

Laresar Grande 2 Sweeping Robot Vacuum Cleaner — 14.4V Li-ion Replacement Battery (INR-32E-4S1P)

This is a 14.4V, 2600mAh Li-ion replacement battery for the Laresar Grande 2 Sweeping Robot Vacuum Cleaner. It matches the OEM part number INR-32E-4S1P and fits the Grande 2's battery bay directly. Voltage and capacity are both matched to the original specification.

• Grande 2 platform fit: The Grande 2 runs its drive motors and navigation board from the same 14.4V rail. This cell pack maintains that voltage through the full discharge curve, keeping both systems stable without a mid-cycle voltage drop that trips the navigation processor.
• Bench tested on actual hardware: We ran this battery through full charge and discharge cycles on the Grande 2 platform. The BMS accepted the charge handshake without error, and the cell pack delivered consistent voltage across motor-start events at the beginning and end of each cycle.
• Dock charging habit for the Grande 2: The Grande 2 sits on its charging dock between cycles, which pushes continuous trickle current into the cells. Remove the vacuum from the dock once charging is complete. Cells held at full charge under constant trickle current lose usable capacity faster than cells that rest off the dock.

Suction dropping before the battery indicator reaches low on the Grande 2

The Grande 2 motor draws significantly more current when the filter is partially blocked or the brush roll is obstructed. That extra draw pulls the cell voltage down faster than the indicator gauge anticipates, so the vacuum loses suction while the indicator still shows charge remaining. The BMS reads actual cell voltage, not the percentage shown on the display. Clean the filter and check the brush roll before concluding the battery is at fault — a clear airpath restores normal draw and normal voltage hold.

Motor cuts out mid-cycle then recovers after a few seconds

This is a BMS overcurrent trip, not a dead battery. When suction is sustained against a blockage — carpet pile compressed over the inlet, or a clogged filter forcing the motor to work harder — current draw spikes above the BMS cutoff threshold and the pack shuts the output. The BMS resets automatically after a short thermal delay, which is why the motor comes back without any user action. Clear the blockage, allow 10–15 seconds, then restart. If the trip repeats on clean floors with a clear filter, check that cell voltage at rest reads above 12.0V before recharging.
