of the charge battery and both - of source and charge connected with the emitter
of the TIP31C transistor.After 4 hours
source from 1.17V to 2.30V (2 AA NiMH)
charge from 1.23V to 8.48V (8 AA NiMH)
So , no expensive wire spools.


ps: can someone replicate and confirm this!
Can you post a exact schematic of your exact setup?
