It fits the pocket-sized GPS unit that pairs wirelessly with a host device to deliver real-time location and route guidance. Voltage, dimensions (52.96 × 33.64 × 5.15mm), and connector match the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHXE-W01 platform fit:\u003c\/strong\u003e\n    The Sumvision Bluetooth GPS Receiver uses a compact single-cell Li-ion pack at 3.7V nominal. This replacement matches the original voltage rail and physical footprint, so the BMS handshake completes without fault codes.\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 HXE-W01 platform and confirmed the BMS accepted the cell at first connection, reached full charge termination cleanly, and held voltage above the low-battery cutoff threshold through a full navigation session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start calibration after fitting:\u003c\/strong\u003e\n    After installing this cell, power the unit on outdoors with a clear sky view before your first trip. GPS units perform a cold start after any full power removal — first satellite acquisition can take 5–10 minutes. Subsequent warm starts drop to under a minute once almanac data is cached.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy reduced at low battery on the HXE-W01\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HXE-W01 receiver draws more current during active satellite tracking than during standby. As cell voltage drops toward the low-battery threshold, some GPS receivers reduce RF front-end sensitivity to extend operating time — this shows up as position drift or slower fix refresh. Replacing a degraded cell that sags under load restores full receiver sensitivity. After fitting this cell, check that voltage holds steady above 3.6V during active navigation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without warning before the low-battery indicator appears\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery indicator is calibrated against the original cell's discharge curve and the fitted cell has aged or degraded unevenly. The display may still show one bar of charge while the actual cell voltage has already hit the BMS cutoff threshold. A new cell with a matched capacity resets this behaviour over one or two full charge cycles. After fitting, run at least one complete charge from flat to full so the BMS can re-map the voltage curve accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377693622362,"sku":"BWCS-XEW01SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377693655130,"sku":"BWCS-XEW01SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377693687898,"sku":"BWCS-XEW01SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XEW01SL-1.webp?v=1778771896","url":"https:\/\/batteryweb.com\/products\/sumvision-bluetooth-gps-receiver-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
