Solac Lucid i10 Replacement Battery 14.4V 2600mAh Li-ion

Solac Lucid i10 / AA3402 — 14.4V Li-ion Replacement Battery

This 14.4V 2600mAh Li-ion battery pack replaces the original cell in the Solac Lucid i10 and AA3402 cordless stick vacuums. It delivers the same voltage and capacity as the factory unit. Dimensions are 69.50 × 37.00 × 37.00mm — verify these against your existing pack before ordering.

• Lucid i10 and AA3402 compatibility: Both models run the same 14.4V battery rail with an identical connector and BMS handshake. One pack covers either unit — the BMS on both accepts the same charge profile from the Solac wall adapter.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge passes on a Lucid i10 unit. The BMS held within spec on both the charge cutoff and the low-voltage protection trip. No thermal events were recorded during testing.
• Dock charging habit on cordless vacuums: Do not leave the Lucid i10 sitting on the charging dock indefinitely between uses. Continuous trickle charging is the fastest way to degrade Li-ion cell capacity on this type of vacuum. Charge to full, remove from the dock, and store off-charge.

Suction dropping before the battery indicator shows low

A partially blocked filter forces the Lucid i10 motor to draw harder than rated current to maintain airflow. The BMS detects the overcurrent condition and steps back motor power before the battery voltage has actually dropped to the low threshold. The battery indicator still shows charge remaining, but suction is already reduced. Clean or replace the filter first — if suction recovers, the battery is not the cause.

Motor cuts out briefly then restarts during use

This is a BMS overcurrent trip, not a flat battery. It happens when the motor hits a sustained restriction — a blockage in the nozzle or a clogged filter — and current draw spikes beyond the BMS protection threshold. The BMS cuts power momentarily, then resets once current drops back into range. Clear any blockage, check the filter, and confirm the pack voltage reads at least 14.4V on a multimeter before assuming the battery is at fault.
