Cameron Sino 650mAh Li-Po Battery for Sena SMH-10S SMH-20S YP802542P

Direct replacement for Sena headsets

This Cameron Sino lithium-polymer battery is built to the original specifications for the Sena SMH-10S and SMH-20S wireless headsets. It matches the YP802542P part number and delivers a 650mAh capacity at 3.7 volts. The pack fits the exact 42.50 x 24.90 x 7.80 mm footprint required by the device. Riders needing a fresh power source for these specific models can install it directly.

Low self-discharge chemistry and protection circuit

Lithium-polymer cells hold their charge well between rides, so the headset is ready after weeks in storage. The integrated protection circuit guards against overcharge, over-discharge, over-voltage and short-circuit events during normal operation. No active cooling is involved, so the battery adds no audible noise to the helmet. Normal use simply requires a standard charge cycle through the headset's own port.

650mAh capacity decides runtime

The 650mAh rating determines how long the headset runs between charges; buyers who need longer talk time must choose a higher-capacity pack if one exists for this form factor. The physical dimensions of 42.50 x 24.90 x 7.80 mm are fixed by the headset's battery bay, so a larger cell cannot be accommodated. Verify the YP802542P part number on your original battery before ordering.
