I’m doing some experiments with a MKR WAN 1310 and a MKR ENV shield with an SD card. In the tech specs of MKR WAN 1310 it’s written: “Supported Batteries - rechargeable Li-Ion, or Li-Po, 1024 mAh minimum capacity”.
For testing I do not need a large battery and I have a 340 mAh Li-Po battery.
a) I assume that I can use this battery?
b) Can I use the built in battery charger for this small battery?
Thank you for your advice.
