Valid values are in range of 0 to 100 inclusive. | |||

| Battery percentage | | Battery percentage (fractional part). | ||
Seems to have a resolution of around 0.1% according to tests. | |||
To calculate battery charge percentage in full resolution: | |||
MCU[0x0B] + (MCU[0x0C] / 256.0F) | |||

| System voltage | | System voltage. | ||
This voltage seems to be measured at the load side, so the voltage reading will always be lower than direct probes across the battery due to the various voltage drops in the system by the time the voltage is measured. | |||
To calculate system voltage in Volts: | |||
MCU[0x0D] * 5 / 256.0F | |||
