It restores pedal-assist and throttle function to the motor system. Voltage and cell chemistry match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTwing Ergo motor system compatibility:\u003c\/strong\u003e\n    The Twing Ergo platform runs a 25.2V nominal rail. The BMS on this pack is calibrated to that rail — it handles the handshake with the motor controller without throwing a fault code on startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through sustained motor-load draws simulating hill-climbing current. The BMS held the output rail steady and did not trip under the peak-draw spikes that cause mid-ride cutouts on worn packs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst ride after winter storage:\u003c\/strong\u003e\n    After the bike sits unused through winter, connect the charger and let the pack charge at the lowest rate available before the first ride. Cold Li-ion cells carry higher internal resistance, and pushing full current through them below 10°C causes lithium plating on the anode that permanently reduces cycle life.\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  \u003cp class=\"bpw-desc-p\"\u003eA fresh pack cutting out on a steep climb is almost always a BMS overcurrent trip, not a faulty battery. Sustained hill-climbing draws a higher continuous current than flat riding, and if the pack's state of charge is below 50%, the BMS voltage floor triggers a protective shutdown before you reach the top. Start long climbs with a full charge. If the cutout keeps happening, check that the battery connector is fully seated — a high-resistance connection causes a voltage drop that the BMS reads as a cell undervolt event.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not accepting the pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter months of storage, individual cells can drift below the charger's minimum acceptance voltage — typically around 20V for a 25.2V pack. Most chargers will not begin a charge cycle on a pack reading below that threshold and simply show no activity. Connect the charger and leave it for 30 minutes without interrupting it. The charger's low-current recovery mode will slowly bring the cells up to the acceptance floor, after which the normal charge cycle will begin automatically.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360285589594,"sku":"BWCS-PFC120SL-1","price":472.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360285622362,"sku":"BWCS-PFC120SL-2","price":563.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360285655130,"sku":"BWCS-PFC120SL-3","price":631.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PFC120SL-1.webp?v=1778611065","url":"https:\/\/batteryweb.com\/products\/kettler-ohne-angabe-replacement-battery-252v-18000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
