hi
It started has an experimentation ...
I used 4 NiMH batteries in serie to directly power a small PIC.
my little circuit run fine for 20 days(kindof) from around 5.2v when all full charged
to 3.x volts (this is fine too)....
my problem are :
only the top ( the one near the +) battery got completely drained, all 3 others got a bit discharged, but the top one got really drain ....
noob question why ? i always tought that all batteries will be drained equally ...
is there some circuits with no regulator (780x) etc . available ( the simpliest the better )...
