So.... I'm working with a teacher whose class reallllly wanted to have all of their Circuit Playground (Classic) projects hung on the wall and on all... the... time... That means ~20-30 projects, each with their own battery. This led to a need to recharge the LiPo batteries (like this https://www.adafruit.com/product/1570), something quite laborious with just a little battery charger for one USB (like this one on Adafruit: https://www.adafruit.com/product/1570)
**Is there a way to charge multiple batteries at a time? **
Many thanks for any tips and tricks!
how to charge multiple LiPo batteries at once?

Re: how to charge multiple LiPo batteries at once?
The only safe way to charge multiple LiPo batteries is with multiple chargers.
A less expensive approach would be to use a larger battery to power all of the projects at once. A 2200 mAh cell like this one is equivalent to 22 of the 100mAh cells you are currently using

We have 4400mAh and 6600mAh batteries as well:

That approach would require building a 'splitter' cable to power multiple circuit playgrounds from the same battery.
