Neabot NOMO N2 Replacement Battery 14.4V 5200mAh

Neabot NOMO N2 — 14.4V Li-ion Replacement Battery (CMICR18650F8M7-4S2P)

This is a 14.4V, 5200mAh Li-ion battery pack for the Neabot NOMO N2 and RS0060B robotic vacuum cleaner. It replaces the original OEM pack when capacity fade reduces suction performance or the unit no longer holds a charge. Voltage and cell count match the original spec exactly.

• NOMO N2 and RS0060B compatibility: Both models run the same 14.4V power rail and use the same BMS handshake protocol. A single cell configuration — 4S2P using 18650 cells — covers both units without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a NOMO N2 unit. The BMS responded correctly to charge termination, over-discharge cutoff triggered at the correct low-cell threshold, and the vacuum's suction motor drew steady current across multiple cleaning passes.
• Dock charging habit on the NOMO N2: Do not leave the NOMO N2 sitting on its dock between every session. Continuous trickle charging at full state-of-charge accelerates lithium cell degradation faster than periodic charge-to-full cycles. Charge when depleted, then remove the unit from the dock once full.

Cordless vacuum losing suction before battery indicator reaches low

This is a voltage sag issue, not a capacity issue. A partially clogged filter forces the suction motor to draw more current than rated, which drops the cell voltage faster than normal and triggers the BMS to reduce output before the indicator registers low. The vacuum appears to be out of charge when the battery still holds significant capacity. Clear the filter first — if suction recovers and the battery lasts longer, the filter was the root cause, not the cell.

Motor cuts out mid-cycle and restarts after a few seconds

This is a BMS overcurrent trip, not a failing battery. When airflow is restricted — blocked filter, tangled brush roll, or a blocked intake — the motor draws a sustained current spike above the BMS protection threshold. The BMS interrupts the circuit and resets after a short recovery window. Check the filter and brush roll before assuming the battery is faulty. If the fault disappears after clearing the blockage, the cell pack is fine.
