Is it possible to power the heltec v3 with NIMH batteries? Like maybe 4 in series (4.8v) or 3 in series (3.6v)?
Would it even charge them or is the charging only for li-ion battery packs like the 3.7v one that everyone suggests?
I don’t want to buy it if I don’t need it, I have old NIMH batteries in abundance and I’m not sure what my final setup should look like yet.
My guess is that you could power the board, but charging will end in disaster.
Nimh isn’t as energy dense as li-ion as I recall? So an 18650 is probably a better bet.
Yeah my plan was without charging. But I found another solution anyways :)
