It matches the single-cell 1S1P configuration and physical dimensions of the OEM pack. Swap it when the original cell no longer holds a charge or the light fails to power on.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3D-Life\/XC142K fit:\u003c\/strong\u003e\n    The XC142K driver circuit runs on a nominal 3.7V single-cell input. The connector pinout and BMS communication match the OEM pack — the light's charge management and low-voltage cutoff functions operate as they did from the factory.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the XC142K platform. The BMS accepted charge without fault flags, and the low-voltage cutoff triggered cleanly at the expected threshold — no premature shutdowns or runaway draws observed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-ride charge discipline:\u003c\/strong\u003e\n    Charge the light fully before any night ride. The XC142K driver steps down output power progressively as cell voltage drops, so a partially charged cell reduces brightness well before the low-battery indicator lights — you lose usable output without visible warning.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLight not reaching rated lumen output on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XC142K driver needs the cell voltage above a minimum input threshold to sustain maximum brightness. If the replacement cell shipped partially discharged — common in storage — the driver can't pull enough current to hit peak lumen output. This isn't a fault with the light or the cell. Charge fully to 4.2V before the first use and retest at full brightness mode.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB charging not accepted after a wet ride\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWater in the USB port interrupts the charge handshake before current even reaches the cell. The XC142K shows no charge indicator and the port may feel cool to the touch — the BMS is not at fault. Leave the light in a dry location with the port facing down for several hours. Once the port is fully dry, reconnect the cable and confirm the charge indicator activates within 30 seconds.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333506072666,"sku":"BWCS-VXC142LS-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333506105434,"sku":"BWCS-VXC142LS-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333506138202,"sku":"BWCS-VXC142LS-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VXC142LS-1.webp?v=1778212956","url":"https:\/\/batteryweb.com\/products\/vancouver-3d-lifexc142k-replacement-battery-37v-450mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
