Veho MUVI K1 Compatible Battery 3.7V 1500mAh VCC-A034-SB

Veho MUVI K1 / K2 Series — 3.7V Li-ion Replacement Battery (VCC-A034-SB)

This is a 3.7V 1500mAh Li-ion battery for the Veho MUVI K1 and K2 action cameras, including VCC-006-K1 and VCC-006-K2NPNG variants. It replaces OEM part VCC-A034-SB and fits directly into the compact camera body. Capacity figures are taken from the product data: 1500mAh / 5.55Wh.

• K1 and K2 platform fit: Both the K1 and K2 share the same cell format, connector pinout, and voltage rail at 3.7V nominal. The BMS in each body uses the same charge-termination handshake, so one cell covers the full model range listed above.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a K2 body. The BMS accepted the cell without fault codes, and charge termination triggered correctly at full capacity. Voltage held steady through moderate continuous-record loads.
• First-use charge protocol for MUVI bodies: On first install, run one complete charge cycle through the camera body or OEM charger before shooting. MUVI bodies map the battery-remaining indicator against a known discharge curve — skipping this step can cause the indicator to read inaccurately from the first session.

Why the MUVI K1 shows a dead battery icon on a partially charged replacement cell

The K1 body stores a discharge curve from the previous cell and uses it to estimate remaining charge. When a new cell goes in, the camera's indicator maps against that old curve until a full cycle resets it. The result is a low or empty battery icon even when the cell is at 3.9V or above. One full charge cycle — from flat to termination inside the camera body — re-calibrates the indicator and clears the false reading.

Battery percentage jumping erratically during recording on the MUVI K2

The K2's fuel gauge samples voltage at fixed intervals and converts it to a percentage using a lookup table tuned to the OEM cell's discharge curve. A replacement cell with a slightly different mid-discharge voltage profile will hit those voltage thresholds at different points, causing the percentage to jump or stall. This does not indicate a faulty cell — it is a calibration mismatch. After two to three full charge and discharge cycles in the camera body, the readings stabilise as the BMS updates its reference points.
