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.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEB 30\/1 and Windsor EB30 platform fitment:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBrush motor engagement care:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on brush engagement — why the EB 30\/1 stops immediately after switch-on\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 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.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSweeper runs weak and brush slows mid-session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eBrush 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416032182362,"sku":"BWCS-KEB301PW-1","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416032215130,"sku":"BWCS-KEB301PW-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416032247898,"sku":"BWCS-KEB301PW-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KEB301PW-1.webp?v=1779759610","url":"https:\/\/batteryweb.com\/products\/karcher-eb-301-cordless-electric-sweeper-12-replacement-battery-72v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
