These are compact handheld communicators — not traditional cameras — that use a slim Li-ion pack to power the display, wireless radio, and audio hardware. Voltage and form factor match the OEM specification at 53.20 × 35.30 × 7.10mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMylo COM-1 and COM-1\/B platform fit:\u003c\/strong\u003e\n    Both Mylo variants share the same battery bay, connector pinout, and BMS handshake protocol. The COMA-BP1 designation covers the full COM-1 series, so one cell works across both colour variants without 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 COM-1 platform. The BMS accepted the cell on first insertion, negotiated correctly with the device, and reported charge state without triggering a fault condition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMylo wireless radio draw:\u003c\/strong\u003e\n    The COM-1's Wi-Fi and VoIP stack pulls significantly more current than the display alone. Keep wireless off when the device is idle — sustained radio-on sessions accelerate cell cycling faster than any other use pattern on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Mylo COM-1 rejects a new cell on first boot\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe COM-1 BMS performs a handshake check when a new cell is inserted. If the cell voltage sits below approximately 3.4V from storage, the device may display a low-battery warning or refuse to boot entirely. This is not a fault with the replacement cell — it is the BMS protecting against an under-voltage start. Connect the device to its OEM charger or USB source and allow a full charge cycle before attempting to power on. After one complete charge, the BMS recalibrates and accepts the new cell without further prompting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or resetting to zero mid-session\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe COM-1's fuel gauge maps voltage thresholds against the original OEM cell's discharge curve. A replacement cell with a slightly different discharge profile can cause the indicator to jump — dropping from 40% to 0% without warning, or resetting after a reboot. The fix is a full calibration cycle: charge to 100%, use the device until it shuts off on its own, then charge back to 100% without interruption. After one full cycle, the BMS remaps its thresholds to the new cell's curve and percentage reporting stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333914984538,"sku":"BWCS-NP60FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333915017306,"sku":"BWCS-NP60FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333915050074,"sku":"BWCS-NP60FU-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP60FU-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/sony-my-line-online-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
