I am making a learning toy which kids can play with and learn basics of programming. But i am tired of keep replacing the AA batteries as they run out in few days. So i am thinking of using rechargeable battery. But i am very worried to use it considering it is kids toy and people says lipo and li ion battery can explode. There are dangers or over charge and heat etc.
Is it safe to use them? Which one to use?
I am using Arduino pro mini 3.3v and some times 5v.
I was planning to use: XCSOURCE 5 pcs 1A 5V Micro USB TP4056 Lithium Battery Power Charger Board Module TE420
I think some users have misunderstood the question and have voted this question to be closed. This questions is very much to deal with programming also apologies if i have not made it clear.
We can get the battery level in the code, but is there any way in code we can some how turn off the charging when the battery has been fully charged.
I am under impression (might be wrong, you can correct me), normal
battery single AA cell dies after some time on heavy use (using dc motor etc). But
rechargeable batteries are bigger with multiple cells in it they will last longer. So if i am running some code in a loop for long time
will the battery get over heated will it be a problem.
