<DIV>Hi</DIV>
<DIV> </DIV>
<DIV>i have a few LCD’s and some other bits arround i want to put together to
make an charger / discharger controlled by and arduino</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>dis charging is easy enough.... and the math to do it also</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>but how about charging... i would like to both be able to regulate voltage
and current... depending on what type of battery i have connected...</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>i plan to have the supply voltage at 18-20V to cover most needs... if not i
rip that old 18amp car battery charger and use the trafo in that one...</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>anyways what is the simple way to control voltage ? and how would i do
current ?</DIV>
