It replaces the original frame-mounted pack and restores pedal-assist function across all assist levels. Dimensions are 373 x 102.4 x 98mm — confirm your existing pack matches before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePulzar \/ Senero \/ Zonar \/ Razer platform fit:\u003c\/strong\u003e\n    These four Batavus models share the same 36V drive architecture, connector pinout, and BMS communication protocol. One pack covers all four frames 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, checking BMS cell-balancing, overvoltage cutoff at 42V, and low-voltage protection at 30V. All cells balanced within 20mV at top of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst ride after winter storage:\u003c\/strong\u003e\n    After three or more months unused, charge this battery slowly on a standard 2A charger before the first ride. Cold Li-ion cells carry elevated internal resistance, and fast charging 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 sustained climb draws sustained high current — often 15A or more on a 36V system. If the BMS detects a discharge rate exceeding its programmed threshold, it trips the output protection circuit and cuts power to the motor controller. This is not a faulty battery. The BMS resets automatically once load drops — coast briefly and pedal-assist will restore. If cut-outs are frequent, lower the assist level on steep climbs to keep current draw within the BMS window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows no activity after the battery sat unused for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf cell voltage drops below roughly 2.5V per cell during storage, the BMS locks the charge port to prevent unsafe charging into a depleted cell. Most chargers read this as an open circuit and show no LED activity at all. Leave the charger connected for 20–30 minutes — the BMS on this pack includes a recovery mode that trickle-charges cells back above the acceptance threshold. Once the pack reaches approximately 3.0V per cell, the charger switches to normal CC\/CV charging and the LED changes to its standard charging colour.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360282247258,"sku":"BWCS-WBS942SL-1","price":421.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360282280026,"sku":"BWCS-WBS942SL-2","price":503.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360282312794,"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\/batavus-pulzar-replacement-battery-36v-13000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
