V.I.O. Stream 3.7V Replacement Battery 1800mAh Li-ion

V.I.O. Stream — 3.7V Li-ion 1800mAh Replacement Battery

This is a 3.7V Li-ion battery rated at 1800mAh (6.66Wh) for the V.I.O. Stream action camera. It slots directly into the Stream's battery compartment and powers the camera's video recording and photo capture functions. No OEM part number is published for this cell.

• V.I.O. Stream platform fit: The Stream runs a single-cell 3.7V Li-ion architecture. This replacement matches that voltage rail and physical footprint — 53.00 × 35.30 × 11.00mm — so the battery seats correctly and the camera's power circuit sees the expected nominal input.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench, monitoring BMS cutoff at the low-voltage threshold and confirming the protection circuit tripped correctly before cell voltage dropped below safe limits. Charge acceptance from empty was clean with no interruptions.
• First-install charge cycle: On first use, run one full charge cycle inside the camera body or OEM charger before shooting. Some action camera BMS systems need that initial in-camera charge pass to calibrate the battery-remaining indicator — skipping it can cause the display to read inaccurately from the start.

Battery percentage jumping erratically on the Stream's display

The Stream's fuel gauge maps voltage to a percentage curve tuned to the original cell's discharge profile. A replacement cell with a slightly different discharge curve hits voltage thresholds at different points, so the indicator can jump — say, from 60% to 30% in one step. This is a display calibration issue, not a fault with the cell. Running two or three full charge-discharge cycles through the camera body allows the BMS to build a more accurate map of the new cell's curve. After those cycles, percentage readouts typically stabilise.

Stream showing no battery or refusing to power on with a new cell installed

If the camera shows a dead-battery icon or simply won't turn on with a freshly installed replacement, the cell may have arrived at a low resting voltage after storage — common with Li-ion shipped in a partial-charge state. Place the battery in the OEM charger or connect the camera to USB power and let it charge for at least 15 minutes before attempting to power on. If the camera body is the charger, hold the charge connection until the indicator light changes state. The BMS will engage once the cell recovers above approximately 3.0V.
