SkyCam Pro 8000i Compatible Battery 3.7V 900mAh Li-ion

SkyCam Pro 8000i / Pro 9500i — 3.7V Li-ion Replacement Battery

This 3.7V 900mAh (3.33Wh) lithium-ion cell replaces the original battery in the SkyCam Pro 8000i and Pro 9500i cameras. Both models run the same battery bay dimensions and voltage rail, so one cell covers the pair. Swap it in when the original no longer holds a charge or the camera refuses to power on.

• Pro 8000i and Pro 9500i fit: Both cameras share the same 3.7V single-cell architecture, connector pinout, and BMS communication protocol — that is why one battery covers both. The voltage rail feeds the imaging sensor, processor, and recording circuits from a common source.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles and confirmed the BMS accepted the cell without a reject flag. Voltage at full charge held at 4.18V, within the expected ceiling for this chemistry.
• First-install charge cycle: Insert the new cell and charge it fully inside the camera body or OEM charger before your first shoot. Some camera BMS systems only map the battery-remaining display correctly after completing one charge cycle from within the camera itself.

Flash output dropping mid-shoot on a new camera battery

When the flash fires repeatedly, the capacitor recharge circuit pulls a short burst of high current from the cell. A new cell with an uncalibrated BMS can interpret this spike as a fault and briefly throttle output. The result is a longer recycle time or a visibly weaker flash burst. One full charge-discharge cycle usually lets the BMS map the cell's actual discharge curve and removes the throttle.

Battery percentage jumping erratically on the Pro 8000i display

The camera's fuel gauge maps voltage thresholds to percentage steps calibrated for the original cell's discharge curve. A replacement cell with a slightly different curve hits those voltage thresholds at different points in its discharge, so the percentage reading jumps rather than stepping down smoothly. This is a display calibration issue, not a fault with the cell itself. Run two full charge-discharge cycles inside the camera body and the indicator will stabilise.
