The BMS in each body communicates with the cell over the same three-pin interface, so one cell works across the whole group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Ezviz S5 body and confirmed the BMS accepted it cleanly on first install. Charge termination triggered correctly at 4.2V and the battery-level indicator tracked accurately through discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle — Ezviz BMS specific:\u003c\/strong\u003e\n    Run one full charge inside the camera body using the original Ezviz cable before extended use. Some Ezviz body firmware maps the battery-remaining display by completing an initial charge-discharge handshake with the new cell — skipping this step can cause the indicator to read inaccurately for the first few sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Ezviz S5 shows a dead battery icon on a freshly charged replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S5 body reads cell state using a voltage-threshold map calibrated to the original BL-06 discharge curve. A new third-party cell can sit at a slightly different resting voltage after its first charge, which pushes it outside the expected threshold window. The camera interprets this as a fault and displays a low or dead battery icon even though the cell is fully charged. One full charge-discharge cycle inside the camera body usually resets the threshold mapping and clears the false indicator.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the Ezviz app after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter replacing the BL-06, some users see the Ezviz app report battery percentage in large jumps — dropping from 80% to 40% with no warning, or bouncing between readings. This happens because the app's percentage calculation relies on a stored discharge curve profile from the previous cell. The new cell's discharge curve doesn't match that stored profile until the camera relearns it. Fully discharge the replacement cell until the camera shuts down, then charge it to 100% uninterrupted — this forces the firmware to rebuild the curve and stabilises the percentage readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333582258266,"sku":"BWCS-EVS600MC-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333582291034,"sku":"BWCS-EVS600MC-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333582323802,"sku":"BWCS-EVS600MC-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EVS600MC_1.webp?v=1778212979"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/collections\/BW-CS-LI90BMC-4.webp?v=1780019647","url":"https:\/\/batteryweb.com\/collections\/camera-batteries-capture-every-moment-without-interruption.oembed","provider":"BatteryWeb","version":"1.0","type":"link"}
