Battery suggestions

[LindyBalboa]

Greetings,

I have gotten my PCBs from JLC and am getting ready to order components. In a few cases I think it would be worth considering battery operation. I was wondering if there are any recommended batteries based on mAh and space. I have searched the site and google, but I didn’t find any specifics. For clarity I have the Pro v3.7 boards.

Thanks!

Just an idea. I reclaimed a battery of an e-cig which have probably a rechargeable small battery like 300mAh. Its enough for 1,5 hours in my case to keep it running while I unplug it to recalibrate it in outside air for example.
