Default 8 6v batteries, how to make it a 36v pack.

OK. This is my project for today since it is raining.

I want to upgrade to 48v's here in the future. I need new batteries for my cart as is. I can get my hands on some t 105 seconds for 60 bucks a battery.

SO.... I am trying to make a 36v pack out of 8 6v batteries.

I was thinking of running two marine batteries for my amp and radio. Then I was thinking well these 6v's are so cheap and have a way better ah rating than the marine batteries.

Then I thought why not wire them in to the system and use the one 36v charger and just get a 12v converter for the electronics.

So if anyone wants to help me draw up a way to wire this in give me some ideas. Don't worry about the converter for now. Just help me wire this puppy to run.

Ok. the big blue box is the actual battery tray in the cart. The red box represents the bag well.

So i am pretty sure this only makes a 36v pack. But I am not sure I have the parallel batteries wired correctly.

Gmorrison where are ya brother.

6 batts in series and the 2 additional ones in parralell in the middle fo the pack.... but you better be monitoring the charging and be prepared to charge the extras with a 12v charger when needed I got work to do You draw it and we will tell you if it will work

Oh..... you did draw it? How come I can't make sense of all that scribble? What did you use an etch-a-sketch ! ????

scotty get the napkin with the coffee stain on it next time. hahaha.

yours looks good too.

do you understand my resasoning on this. I can get a deal on 8 6v's but when I upgrade to 48v I want them all to be the same "age". So i am trying to run them all while I have just the 36v cart.

The way you have that drawn it looks like the first extra bat (being parallel with nbr 3 in the pack) would be 18V, nbr 1 + nbr 2 + nbr 3 = 18 volts. Then the second extra bat would be 24V being parallel with nbr 4. Please correct me if I am wrong.
Thanks
