It replaces OEM part BP-LP850\/11-A1 L. Swap it in when the original cell no longer holds a charge or causes unexpected shutdowns mid-route.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS-series model compatibility:\u003c\/strong\u003e\n    The S30, S50, S70, and S80 share the same 3.7V single-cell architecture, identical connector pinout, and the same physical battery bay dimensions — so one cell fits all four models without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the S-series platform. The BMS accepted a full charge without error flags, and the device voltage curve stayed within the expected 3.0V cutoff to 4.2V ceiling throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After fitting a new cell, take the unit outdoors and power it on before driving. A full power interruption clears the GPS receiver's satellite almanac, so the first fix after a swap takes 5–10 minutes. Subsequent power cycles warm-start and lock much faster.\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 when battery level drops below 30%\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Navman S-series units scale back GPS receiver sensitivity at low battery to protect the cell from deep discharge. The unit stays on, but satellite signal strength drops and position updates can become less frequent. This isn't a faulty battery or antenna — it's the device managing draw. Keep the unit charged above 30% during active navigation to maintain full receiver output.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a battery swap, the S-series fuel gauge is uncalibrated to the new cell. The on-screen battery indicator can still show two or three bars when the cell voltage is already near the 3.0V cutoff threshold. The device then cuts power without the usual warning. Run two or three full charge and discharge cycles to let the fuel gauge re-calibrate to the new cell's actual capacity curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377740316762,"sku":"BWCS-ICS30SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377740349530,"sku":"BWCS-ICS30SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377740382298,"sku":"BWCS-ICS30SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICS30SL_1.webp?v=1778771922","url":"https:\/\/batteryweb.com\/products\/navman-s30-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
