Neatsvor X500 Replacement Battery 14.4V 2600mAh Li-ion

Neatsvor X500 / G30 / G20 / R500 — 14.4V Li-ion Replacement Battery

This is a 14.4V 2600mAh Li-ion battery for the Neatsvor X500, G30, G20, and R500 cordless vacuum cleaners. These models share the same voltage rail, connector format, and BMS communication protocol. Capacity is sourced from product data at 2600mAh (37.44Wh).

• X500, G30, G20, R500 platform: These four models run the same 14.4V motor drive circuit and use an identical battery housing with the same latch geometry and contact arrangement. The BMS in each unit expects the same handshake sequence, so one cell fits all four without modification.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge on the X500 motor board. The BMS held cutoff correctly at low-voltage threshold and accepted charge current without fault flags on the dock charger.
• Dock charging habit on the X500: Do not leave the vacuum sitting on the charging dock permanently. Continuous dock charge subjects Li-ion cells to trickle current that accelerates capacity fade. Charge to full, then remove from the dock until the next use.

Suction dropping before the battery indicator reaches low on the X500

The X500 motor controller reduces power output when cell voltage sags under load — this happens before the indicator LED steps down. A partially blocked filter forces the motor to draw above rated current, which accelerates voltage sag on the cell. The battery reads fine at rest but collapses under sustained motor load. Clean the filter first; if sag continues on a clean filter, the cell has lost capacity and needs replacement.

Motor cutting out mid-clean then recovering after a few seconds

This is a BMS overcurrent trip, not a motor fault. When suction is restricted — blocked brush roll, clogged filter, or a hard floor-to-carpet transition — current draw spikes and the BMS opens the discharge circuit to protect the cell. After a few seconds the BMS resets and the motor restarts. Clear the restriction and check the filter. If trips continue on an unobstructed vacuum, measure resting cell voltage; anything below 14.0V on a charged pack signals a degraded cell.
