It replaces the original pack when capacity has faded from regular charge cycles. Voltage and form factor match the stock battery housing and connector layout on these frames.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAssen, NLD 03, and Sevilla compatibility:\u003c\/strong\u003e\n    These three Victoria models share the same 25.2V battery rail, connector pinout, and BMS communication protocol — which is why one pack services all three. Swapping between them requires no 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 full charge and discharge on a 25.2V e-bike test rig. The BMS held steady through simulated motor-start current spikes and re-engaged correctly after a low-voltage cutoff event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eWinter storage charge protocol:\u003c\/strong\u003e\n    After winter storage, charge this battery slowly before the first ride. Cold Li-ion cells carry higher internal resistance, and fast charging below 10°C causes lithium plating on the anode that permanently reduces cycle count.\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 fresh battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSustained climbing draws peak current for longer than flat riding — sometimes long enough to trigger the BMS overcurrent cutoff. This is not a battery fault. The BMS trips to protect the cells when sustained draw exceeds the pack's rated discharge ceiling. Releasing the throttle for two to three seconds resets the BMS latch and restores power. If cutouts happen on moderate gradients, check that the battery terminals are fully seated — a loose connection raises contact resistance and pushes the BMS into protection mode at lower current thresholds.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing no charge activity after the bike sat unused for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA pack left discharged for several months can drop below the charger's minimum acceptance voltage — most e-bike chargers refuse to push current into a pack reading below roughly 20V at the terminals. The BMS has also likely engaged deep-discharge lockout. Connect the charger and leave it attached for 30 minutes without interruption; the trickle stage will slowly raise cell voltage until the BMS unlocks and normal charge resumes. If the charger LED never transitions from red to green after 60 minutes, check the charger output voltage with a multimeter — it should read at least 29.4V off-load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360284180570,"sku":"BWCS-PFC120SL-1","price":472.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360284213338,"sku":"BWCS-PFC120SL-2","price":563.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360284246106,"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\/victoria-assen-replacement-battery-252v-18000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
