This is a question I have wanted to ask for some time. When you have a battery bank, in my case 3 4volt 1104 amp/hr batteries for a 12 volt system, my useable amperage is approx 552 amps. If I where to add 3 more batteries of equal amperage and maintain 12 volts, I increase my useable amperage, to 2208 amps. Now if I where to change this to a 24 volt system, what is my advantage other than a possible down size in wire. By going to a 24 volt system I lose the increased amperage. Two other examples I know of are, a 12 volt system of 9 4 volt batteries, storage 3312 amps and the other is a 24 volt sysem made up of 12 4 volt 1104 amp/hr batteries, storage 1104 amps. I just don't understand, can someone explain?
No announcement yet.
12, 24 or 48 volt
