power bank related circuits are very less in net .
decided to make one
my 18650cells i bought 3year back
never used ...but they showed 3.7V when tested !
I kept for 10hour charge... the cell voltage is 3.82V now
current is 200mA
why so slow charge ?
can you suggest better circuit , "no special batt charger IC"
