If I want to integrate the P-70 with my own battery and hardware system, what is the supported input voltage range?

The P-70 is available in two interface versions: USB and TTL (UART).
USB Version
- Safe input voltage range: 3.3V to 6.0V
- Recommended operating voltage: 3.6V to 5.5V
TTL (UART) Version
- Safe input voltage range: 3.0V to 6.0V
- Recommended operating voltage: 3.3V to 5.5V
Important:
The supply voltage should never exceed 6.0V, as applying a higher voltage may permanently damage the device.
