It uses OEM part number 941-925552-011 and fits directly into the RG1100 chassis. The RG1100 is a portable Wi-Fi hotspot that shares mobile data across multiple connected devices.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRG1100 platform fit:\u003c\/strong\u003e\n    The RG1100 runs a combined cellular modem and Wi-Fi radio stack off a single 3.8V cell. Both the connector pinout and BMS handshake protocol match this pack — no adapter or firmware workaround needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simultaneous modem and Wi-Fi load. The BMS held the 3.8V rail stable across the full discharge curve and triggered low-voltage cutoff cleanly without false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during extended sessions:\u003c\/strong\u003e\n    Keep the RG1100 in an open, ventilated spot when running for long periods. The cellular radio ramps to maximum transmit power when connected devices are far away or signal is weak — that extra draw generates heat the battery absorbs directly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRG1100 dropping connected devices mid-session on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the RG1100 is at maximum client connections, the combined modem and Wi-Fi radio draw spikes sharply. If the cell voltage sags below the BMS protection threshold during that spike, the device resets and all clients disconnect. This happens more often in poor signal areas because the modem runs at full transmit power, compounding the draw. A genuine 3800mAh cell with a low internal resistance maintains the voltage rail through those peaks where a degraded or undersized cell cannot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRG1100 stuck at black screen after sitting unused for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-polymer cells self-discharge during storage. If the RG1100 sat long enough, the battery may have dropped below the minimum boot voltage the device needs to initialise. Plug it into the charger and leave it for at least 30 minutes before pressing the power button — the BMS needs to see enough charge to release the deep-discharge lockout. If the charge LED does not light within five minutes of connecting, try a different cable and adapter rated at 5V\/1A or higher.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377794220122,"sku":"BWCS-FWG110SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377794252890,"sku":"BWCS-FWG110SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377794285658,"sku":"BWCS-FWG110SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FWG110SL-1.webp?v=1778772243","url":"https:\/\/batteryweb.com\/products\/jexstream-rg1100-replacement-battery-38v-3800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
