A 12-volt battery can certainly be substituted for two 6-volt batteries. Of course not all batteries of the same voltage are created equal, so they would need to be three appropriate 12-volt batteries.In a 42v Western Golf Cart there are 7 - 6v batteries. Can 3 - 12v batteries be substituted for 6 of the 6v batteries?
Simply changing from 6-volt to 12-volt batteries won't save you any weight at all. For a given total capacity, whether the lead plates and electrolyte are divided into two boxes (two 6V batteries) or in one battery (one 12V battery) doesn't make any difference to total weight.I was just thinking the less batteries the less weight and less cost to replace the next time but if the specs won't match up that may not be possible. What are the requirements to match the 3 - 12v batt with 1 - 6v? if the ampere hour are the same is that all that is needed?
So, six 6V batteries in series to drive the motor, and one separate battery for the other stuff. Interesting. A voltage converter would be obvious and more convenient, but that wouldn't have been so practical a couple of decades ago.Are those really wired in series?
My old c-car had something called an “aux” battery that ran lights, contactors and dash stuff.
It was separate from the traction batteries
