Hey all first off this site is 100% absolutly perfect and has helped me twice in the past........so Here I am again.....For some reason I am a little handy with things and items seem to get dropped off at my place when everyone else gives up. So in turn I have a Electric Golf Cart that has showed up, it has 6 which look to me like 8 VOLT batteries in it and the charger says 48 volts, doing the math 6x8 = 48 seems right, after cleaning all the connections and filling the almost dry ones with distilled water and 2 days on the batt charger it runs for about 6 minutes and its dead, I charged up all the batts again and load tested them. I could not get any of them to pull over 200 amps without dropping to about 4 volts. So lets say the batts are needing replaced.
OK my question....Why cant I buy 4 12 VOLT deep Cycle batteries and hook them up in series to create 48 VOLTS ??? If so what is the proper connection order ??? I priced out 8 volt trojan Batteries and without taking out a small mortgage I cant buy them, almost $159.00 EACH...times 6 !!!! Any and ALL help would be wonderful....in case it matters this is a CLUB CAR GOLF CART. Thanks Shawn P.S. Sorry about where this is posted there is no area for GOLF CARTS !!!!
Sams club $77 each
Yes, 4 12 volt batteries will work, verify your main positive and your main negative wires, the rest of the battery wires are just connecting the batteries together. So starting from the battery that you have identified as the one with the main negative wire, connect the positive post to the next battery on it's negative post, then from it's positive post to the next battery's neg post, ( series connection) and so on until 4th battery is connected.
I think your idea will work. As far as wireing. Picture the four batteries in two rows of two. Each battery has the positive terminal at the top left corner and the negative at the bottom right corner. You connect the top right battery negative post to the bottom right battery possitive post. Do the same for the left two batteries. You now have two banks of 24 volts. Now connect one of the remaning open possitve posts to one of the open negatives. you will now have 48 volts at the last two posts.
U can use 4 12volt batteries but they won't run as long on a single charge plus u run the risk of under volting the motor as the charge weakens.
Well it does seem like it is the batts you got to go neg to neg pos to pos it should work all the way around i would check ebay on the batt cheap there
