It replaces the original frame-mounted pack that powers the pedal-assist motor system. Fits the Sduro, FullNine RC, FullNine RX, HardNine RC, and five additional models in the same platform family.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSduro and FullNine platform compatibility:\u003c\/strong\u003e\n    These models share the same 36V battery bay geometry, connector pinout, and BMS communication protocol — which is why a single pack covers the full range. Swapping between them requires no adapters or wiring changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated motor-start loads and sustained climb simulations. The BMS handled peak current draw without tripping into protection mode, and cell balance held tight across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst ride after storage:\u003c\/strong\u003e\n    If the bike has sat unused over winter, connect the charger for at least two hours before taking the bike out. Cold Li-ion cells carry higher internal resistance, and pushing the motor hard on a cold, partially charged pack accelerates capacity fade at the anode level.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eE-bike motor cutting out mid-hill on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn steep inclines, the motor draws sustained high current that can spike beyond the BMS protection threshold — even on a fully charged pack. When that happens, the BMS cuts power to protect the cells, and the motor goes silent mid-climb. This is more common on first use because the cells haven't been through a full conditioning cycle yet. Running two or three complete charge-discharge cycles normalises cell resistance and raises the effective cutoff ceiling so the BMS trips less readily under climbing load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not accepting the pack after long-term storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs left uncharged for months can drop below the minimum acceptance voltage that most chargers require to begin a charge cycle. The charger sees the pack as a fault condition and refuses to start. Connect the charger anyway and leave it plugged in for 30 minutes — most chargers will trickle current into the pack until the cell voltage climbs back above the threshold, typically around 30V, at which point normal charging resumes automatically.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360281821274,"sku":"BWCS-WBS942SL-1","price":421.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360281854042,"sku":"BWCS-WBS942SL-2","price":503.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360281886810,"sku":"BWCS-WBS942SL-3","price":565.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WBS942SL-1.webp?v=1778611066","url":"https:\/\/batteryweb.com\/products\/haibike-sduro-replacement-battery-36v-13000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
