I need to extend the operation of the Pi on battery for a long period of time, so I need to use another battery than the flat top unprotected 18650 battery.
What are the characteristics my battery should meet ?
- Li-on or Li-po ?
- 3.7V or other ?
- a max capacity ?
- JST-SFH connector ?
If I use an external battery, may I use the Qwiic connector with, for example, this Adafruit LC709203F LiPoly / LiIon Fuel Gauge and Battery Monitor ?
Thank you !
