Proscenic NEO 830P Replacement Battery 14.4V 3400mAh

Proscenic NEO 830P / NEO 820P — 14.4V Li-ion Replacement Battery

This 14.4V 3400mAh (48.96Wh) lithium-ion battery fits the Proscenic NEO 830P and NEO 820P cordless stick vacuums. It replaces the original pack when capacity has dropped and suction no longer lasts a full clean. Voltage and cell count match the original specification exactly.

• NEO 830P and NEO 820P compatibility: Both models run the same 14.4V battery rail with an identical connector and BMS handshake. The same cell pack powers both units, so one replacement covers either machine in your household.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the NEO 830P motor assembly. The BMS handled current draw correctly across both standard and MAX suction modes, with no unexpected cutoff events during testing.
• Dock charging habit on cordless stick vacs: Do not leave the NEO 830P sitting on its charging dock permanently. Continuous trickle charge accelerates capacity fade on lithium cells in this form factor. Charge to full, then remove the vacuum from the dock until the next use.

Cordless vacuum losing suction before the battery indicator reaches low

This happens when the motor draws more current than the BMS expects — usually because a partially blocked filter increases motor load. The BMS reads elevated current as a low-voltage condition and starts throttling output before the indicator reflects actual charge remaining. The vacuum feels like it's running out of battery, but the real cause is restriction in the airflow path. Clean the filter first, then retest — suction should hold consistent until the pack drops below 12.0V.

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

This is a BMS overcurrent trip, not a faulty battery. When suction is restricted — blocked filter, tangled brush roll, or a tight carpet pile on MAX mode — the motor pulls a sustained current spike above the BMS cutoff threshold. The BMS shuts the circuit to protect the cells, then resets after a few seconds once current demand drops. Fix the restriction before assuming the battery is the cause. If the cutout persists with a clear filter and clean brush roll, check that the replacement pack's BMS is communicating correctly with the charger by verifying the charge LED illuminates solid within 30 seconds of docking.
