It replaces the original pack when cell degradation has cut your usable range on daily urban rides. Fits the Navigator Compact Urban motor and charging system directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNavigator Compact Urban motor system:\u003c\/strong\u003e\n    The Navigator Compact Urban runs a 36V drive rail. This pack matches that voltage and the connector format the controller expects. A mismatched voltage trips the BMS before the motor turns over, so the 36V spec here is not interchangeable with 24V or 48V packs from other Prophete models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a 36V e-bike test rig, monitoring BMS cutoff thresholds under simulated pedal-assist load. Cell balancing kicked in correctly at the top of each charge, and the low-voltage cutoff fired at the expected threshold before any cell dropped into damage range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst ride after installation:\u003c\/strong\u003e\n    Do not run the battery flat on its first outing. E-bike BMS firmware on this platform reads State of Charge from a reference cycle — a full initial charge followed by a normal ride lets the controller calibrate the fuel gauge accurately from day one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-hill on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA sustained climb pulls significantly more current than flat pedal-assist riding. If the battery cells are cold or have not completed a full charge cycle yet, internal resistance is higher and the pack voltage sags sharply under that load. The BMS reads the sag as a low-voltage fault and cuts the motor to protect the cells. Warm the battery to room temperature before a hilly ride and ensure it has completed at least one full charge so the BMS has a clean voltage baseline.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger LED stays green or off immediately after connecting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome 36V e-bike chargers require the pack voltage to sit above a minimum acceptance threshold — typically around 30V — before they enter CC\/CV charge mode. A pack that has been in storage can drift below this level, and the charger interprets it as \"full\" or refuses to engage. Connect the charger and leave it undisturbed for 30 minutes; most units trickle at a low rate until cell voltage climbs above the acceptance floor, at which point the charging LED switches to red and normal charge current begins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360276119642,"sku":"BWCS-PRT360SL-1","price":363.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360276152410,"sku":"BWCS-PRT360SL-2","price":433.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360276185178,"sku":"BWCS-PRT360SL-3","price":485.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRT360SL-1.webp?v=1778611066","url":"https:\/\/batteryweb.com\/products\/prophete-navigator-compact-urban-replacement-battery-36v-11600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
