I have a home made batter pack consisting of (8) 3 volt batteries. I need a charger so does this mean I need to get a 24V charger? I'm curious because if it's a battery pack, wouldn't the charger charge each individual battery cell up to its peak voltage, therefore not needing a 24 volt charger?
skepitka has right answer for you i think reserch it more before doing things like this its DANGEROUS TO MESS WITH THINGS YOU KNOW NOTHING ABOUT AND DON'T THINK YOU DO
Depends, are they wired in series or in parallel? In series, it would be 24V, if wired in parallel it would be 3 volts. You should not be making homemade battery packs if you dont know these basic fundamental properties of electricity. You going to blow up the batteries and hurt yourself.
Be careful, Andrew. Improperly charged batteries can catch on fire, and even explode. You need to do a LOT more homework before you try this. For example, from your post I can tell you are not clear on the difference between a serial and a parallel battery pack. That's pretty basic, so I don't think you know enough yet to be hooking things up to live current. PLEASE do more reading! I wouldn't want you to hurt yourself or someone else.
