It fits the HXE-W01 platform and restores power to the GPS receiver and Bluetooth radio. Voltage and cell dimensions match the original at 52.96 × 33.64 × 5.15mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM1, M1 BT GPS, M6 platform fit:\u003c\/strong\u003e\n    These models share the HXE-W01 battery format — same voltage rail, same physical footprint, and the same connector orientation. Swapping between them requires no adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the HXE-W01 platform. The BMS accepted the cell without fault codes, and the Bluetooth radio paired correctly at full and low charge states.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst fix after battery swap:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it run a full cold start. With no satellite almanac cached, the first fix takes 5–10 minutes. Subsequent warm starts drop to under a minute once the almanac is written back to memory.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy dropping as battery level falls\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome GPS receivers reduce radio sensitivity at low battery to protect the BMS from voltage sag under full receiver load. On the HXE-W01 platform, this appears as position drift or wider accuracy circles rather than a clean signal loss. The fix is straightforward — keep the cell above 3.5V during active navigation. If accuracy degrades before the low-battery indicator fires, the cell has aged past useful capacity and needs replacement.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without warning during navigation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe on-screen battery indicator on these receivers is calibrated to the original cell's discharge curve. A new or aged cell can throw that calibration off, meaning the unit hits its protection cutoff voltage — typically around 3.0V — before the indicator shows a low-battery warning. If this happens, charge the unit fully, then run a complete discharge cycle in active GPS mode to let the indicator recalibrate to the new cell. After one full cycle, the warning should fire before the BMS trips.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377692082266,"sku":"BWCS-XEW01SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377692115034,"sku":"BWCS-XEW01SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377692147802,"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\/itrek-bluetooth-gps-receiver-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
