This question pertains to my electric golf cart but the manufacturer(s) have not been of help so I hope it's ok to post here.

The cart has six 8 volt batteries in series for a total of 24 volts. An "on board computer" controls the external charger.

I also have a 24 volt fan. I have been running off 3 batteries at a time, switching between sets periodically. The charging system reads all 6 as a whole pack so the 3 used get undercharged and the other 3 overcharged.

If I set up two sets of three batteries in series and connect them in parallel (pos to pos and neg to neg) I should still get a total of 24 volts and so be using all 6 batteries simultaneously. Am I correct or will the primary (6 battery) series connection cause that configuration to be 48 volts?

Are there any downsides to this proposed configuration?

Getting at all the components and making all hookups just to try it is a major PITA so an expert opinion would be greatly appreciated.

TIA
