I have Trojan t875 batteries that I just put in the cart. 5 are at 8.5 (is that good enough to Run the cart well?) one battery with is connected to the positive post will only get up to about 5-6 volts. The cart stutters if you apply the throttle. Any thoughts? thanks!

One Battery is bad.

How long after you took the cart off the charger, did you get them readings

There is probably a dead cell in the battery reading 5-6V. Either a bad intercell weld, or an internal short which slowly discharges that cell. That bad cell will eventually bring down the whole pack. The old addage; 'only as strong as it's weakest link' so appropriately applies to battery packs.

are you positive you put the charge cables back on the right batteries and that one isn,t out of the loop?.....................................
