It replaces the original pack directly, restoring full blade motor power for cordless cutting. Voltage and capacity match the stock specification from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRM1000 platform fitment:\u003c\/strong\u003e\n    The RM1000 runs a 28V motor rail with a specific connector and BMS handshake. This pack matches that voltage rail, so the mower's onboard electronics recognise and accept the battery without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated blade-motor inrush loads. The BMS handled repeated high-draw spikes without nuisance tripping, and cell balancing stayed stable across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before the first cut of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current can trip the BMS on a cold pack before the mower even starts cutting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff during thick-grass or wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RM1000 blade motor draws peak current when it bites into dense or wet grass — inrush can spike several times the steady-state draw. If the BMS sees that spike exceed its protection threshold, it cuts power instantly to guard the cells. This usually shows as the mower stopping dead mid-row with no warning. Clearing the fault is straightforward: release the handle, wait 10 seconds, then re-engage — the BMS resets once the overcurrent event clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after the mower sat all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly in storage. After several months in a cold garage, a pack can drop below the charger's minimum acceptance voltage — typically around 20–22V on a 28V system — and the charger refuses to begin a charge cycle, showing a fault or red indicator instead. Most chargers include a recovery or \"wake-up\" mode: hold the charge button for 5 seconds or consult the charger label for the recovery input. If the pack voltage reads above 20V on a multimeter, recovery is almost always possible.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381296824410,"sku":"BWCS-YFA800PW-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381296857178,"sku":"BWCS-YFA800PW-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381296889946,"sku":"BWCS-YFA800PW-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-YFA800PW-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/biltema-rm1000-replacement-battery-28v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
