Neabot N1 Replacement Battery 14.4V 6700mAh Li-ion

Neabot N1 / N2 / L8850 — 14.4V Li-ion Replacement Battery

This is a 14.4V lithium-ion replacement battery rated at 6700mAh (96.48Wh) for the Neabot N1, N2, and L8850 robot vacuum cleaners. It replaces the original cell pack when capacity has faded or the battery no longer holds charge. Swap it in to restore the vacuum's cleaning performance without replacing the full unit.

• N1, N2, and L8850 compatibility: These three models share the same 14.4V battery platform, connector pin-out, and BMS communication protocol — so one cell pack works across all three without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a matched load. The BMS held the cutoff voltage cleanly and did not trip false overcurrent flags during motor-start draw spikes.
• Dock charging habit for robot vacuums: Do not leave the N1 sitting on the charging dock between cleaning sessions indefinitely. Continuous trickle charge accelerates capacity fade in lithium cells. Charge fully, then lift the unit off the dock until the next run.

Suction dropping before the battery indicator reaches low

The N1's motor draws significantly more current when the filter is partially blocked or the brush roll is restricted. Under that elevated load, the cell voltage sags earlier than the BMS threshold for a low-battery warning — so the vacuum loses suction while the indicator still reads mid-charge. This is not a battery fault; it is motor voltage sag caused by restricted airflow forcing above-rated draw. Clean the filter and check the brush roll for hair tangles before assuming the cell pack needs replacing. A healthy replacement pack will hold voltage better under load, but a blocked filter will degrade any cell faster.

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

This is a BMS overcurrent trip, not a dead battery. When sustained suction restriction — from a clogged filter or a jammed brush — forces the motor to pull current above the pack's overcurrent threshold, the BMS disconnects the output to protect the cells. The trip resets automatically once current drops, which is why the vacuum restarts after a brief pause. Check and clean the filter first; if the cutout continues on a clear filter with a new pack, the motor itself may be drawing above spec. Measure motor supply voltage during operation — it should hold above 12.5V under normal carpet load.
