Help with SG build..thanks

batteries in parallel is the way to go. in series they resistance is additive as is the voltage. as you string them in series your potential (spike voltage VS battery voltage) diminishes, you will often see the first battery charge better than the rest this way. if you diode isolate each one in parallel they will not swap voltage. diode on positive of each battery or else they will bleed voltage since the ground is common to each other. electrically isolate each battery in parallel.

Tom, In this configuration is it normal to see one battery possibly soak up more charge? I am trying this on a couple sulphated 8V Trojan's and notice that one is receiving more. I presume this would be due to different impedance or voltage of the batteries. I did test it with some good 12V starter batteries and they were more or less even so I have probably answered my own question

if youre trying to desulphate batteries it seems to work best to do one at a time
