Lydsto G2 Cordless Vacuum Compatible Battery 14.4V 6700mAh

Lydsto G2 / HS1 / L1 / R1 Series — 14.4V Li-ion Replacement Battery

This 14.4V 6700mAh lithium-ion battery pack replaces the original power cell in the Lydsto G2, HS1, L1, and R1 cordless vacuums, plus four additional compatible models in the same family. It restores suction performance when the original cell can no longer hold a usable charge. Capacity is 96.48Wh — matched to the stock specification.

• G2 / HS1 / L1 / R1 platform compatibility: These models share the same 14.4V voltage rail, connector format, and BMS handshake protocol, which is why a single cell works across the range. Swapping to a different voltage pack — even slightly — will cause the motor controller to refuse startup or trip immediately under load.
• Bench tested on actual hardware: We cycled this pack through repeated motor-start and sustained suction loads. The BMS held stable across all draw profiles, with overcurrent protection tripping correctly on blocked-airflow simulation rather than during normal cleaning use.
• Dock charging behaviour on the G2 series: Do not leave the vacuum sitting on the charging dock permanently. Continuous dock charge forces a low-level trickle current through the cells even after they reach full charge, accelerating capacity fade. Charge to full, then remove the unit from the dock.

Suction dropping before the battery indicator reaches low

The battery indicator on the G2 reads state of charge, not voltage under load. When the motor draws hard — especially on carpet or with a partially blocked filter — pack voltage sags below what the motor controller needs to maintain full suction, even though the indicator still shows charge remaining. A degraded cell makes this worse because internal resistance rises with age, increasing the voltage drop under load. If suction noticeably drops but the indicator shows 50% or more, check the filter first, then assess whether the battery is holding voltage under load.

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

This is a BMS overcurrent trip, not a motor fault. When airflow is restricted — blocked filter, clogged brush roll, or sealed inlet — the motor works harder to maintain suction and draws current beyond the BMS protection threshold. The BMS shuts the pack down to prevent cell damage, then resets once current drops. Clear the restriction and the trip stops. If it continues with clean filters, measure resting pack voltage — a healthy 14.4V nominal pack should sit above 15.8V fully charged.
