Part number BL-4BS. It fits directly into both models and restores power to the hotspot when the original cell has degraded or failed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGmate and Gmate Plus compatibility:\u003c\/strong\u003e\n    Both models use the same BL-4BS cell, voltage rail, and connector pinout. The BMS handshake is identical across both variants, so this single cell covers the full Gmate line without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell under combined WiFi broadcast and LTE modem load — the conditions that draw the most current. The BMS held stable voltage throughout and did not trip on the startup surge when the cellular radio initialised.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eVentilation during extended sessions:\u003c\/strong\u003e\n    Keep the hotspot on a hard, flat surface during long sessions. When connected devices are far from the hotspot, the cellular radio runs at maximum transmit power. That heat accumulates inside the casing and stresses the cell directly — a clear surface lets it dissipate.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHotspot disconnecting users mid-session on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gmate runs two radios simultaneously — the LTE modem and the WiFi access point. When multiple devices are connected and the cellular signal is weak, both radios operate at peak draw at the same time. This creates a combined current spike that can pull the cell voltage below the BMS cutoff threshold momentarily. The result is a brief power interruption that drops all connected clients. Reducing the number of active devices or moving closer to a cellular tower lowers the combined draw and stabilises the voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHotspot won't power on after sitting unused for several weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the Gmate sat unused long enough, the cell voltage can drop below the minimum boot threshold — typically around 3.0V — and the device will show no response when you press the power button. Connect the hotspot to a charger and leave it for at least 30 minutes before attempting to power it on. If the charge LED does not activate, the cell may have dropped below the BMS recovery floor; in that case, disconnect and reconnect the charger to trigger a re-initialisation cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377811390554,"sku":"BWCS-SKW920SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377811423322,"sku":"BWCS-SKW920SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377811456090,"sku":"BWCS-SKW920SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SKW920SL-1.webp?v=1778772259","url":"https:\/\/batteryweb.com\/products\/skyroam-gmate-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
