Hi, I'm working on a fun project to build a custom battery charger. Here's my specs below.
it has to charge 8 x 1.2v aaa rechargeable battery nimh in series = 9.6v
currently i'm using a 12v generic charger.
I found this schematic (attached picture) and got it to work but someone told me that the circuit I have is just a voltage regular, it doesn't monitor the current level and this circuit can over charge the batteries? I was wondering if there's anyway to improve on this schematic and not over charge the batteries to cause a fire or something. I read somewhere that I can buy this chip LT1513CR for my purpose since I'm using 8 batteries in series, but I want to build my own circuit and play around with it. Anyway to improve my circuit to do things similar to the LT1513CR chip? Can someone please help?
Thanks in advance,
Tyler
