Kärcher EB 30/1 Cordless Sweeper Compatible Battery 7.2V 2500mAh

Karcher EB 30/1 Cordless Electric Sweeper 12" — 7.2V Li-ion Replacement Battery (1.545-100.0)

This 7.2V 2500mAh Li-ion battery is a direct replacement for the Karcher EB 30/1 Cordless Electric Sweeper 12" and compatible Windsor Radius Mini EB30 Commercial Cordless Floor Sweeper. It fits models listed under OEM part numbers 1.545-100.0 through 1.545-111.0 and related variants. Voltage and cell count match the original pack spec exactly.

• EB 30/1 and Windsor EB30 platform fitment: Both the Karcher EB 30/1 and Windsor Radius Mini EB30 share the same 7.2V cell configuration, connector footprint, and BMS handshake protocol — that is why one battery serves both platforms without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the EB 30/1 motor circuit. The BMS held within spec on startup draw and did not trip on repeated brush-engagement cycles across multiple test runs.
• Brush motor engagement care: On first use, run the sweeper at light load — clear, flat hard surfaces — for two cycles before tackling deep debris or thick leaf accumulation. This lets the BMS profile the brush motor's startup inrush current before setting its overcurrent protection thresholds.

BMS cutoff on brush engagement — why the EB 30/1 stops immediately after switch-on

The EB 30/1 brush motor draws a short inrush spike the moment it engages. On a depleted or cold pack, cell voltage drops sharply under that load and the BMS reads it as an overcurrent event and cuts the circuit. The sweeper powers off instantly — often within one second of switch-on. Charging the pack to full before use keeps cell voltage high enough to absorb that startup spike without tripping the BMS cutoff.

Sweeper runs weak and brush slows mid-session

Brush speed drops and debris clearance weakens when cell voltage sags under sustained motor load. This is not a motor fault — it is voltage sag from elevated internal cell resistance, common in packs that have been shallow-cycled repeatedly or left in partial states of charge for extended periods. Check the terminal voltage under load with a multimeter; anything below 6.4V while the motor is running points to a degraded cell stack. A fresh pack at full charge will restore brush torque and consistent sweep speed.
