Customer Question

We recently purchased a 2008 club car carryall and it has been converted to a 6 x 8 volt battery bank 2 rows of 3. The batteries were taken out and we are unsure how to replace them in the correct sequence. They are Trojan T875's. Is it possible to get the sequence they should be put in

Hello I will help,

Are you asking how they are wired?

Customer: replied 11 months ago.
the battery charger is also wired into the vehicle and need to work how to put the batteries back in
Expert:  George H. replied 11 months ago.

The batteries are wired starting at the negative cable to the first battery negative post then the positive post of that battery to the negative post of the next and so on in a chain til you reach the last battery positive post which connects to the positive cable to the controller. Both the negative and positive cables are up front of the battery compartment in the middle of the cart. The charger should connect to the controller if it is self contained.

Is that clear on the batteries? It is one long chain.

This is for a carryall and the controller is behind the battery pack. Does it matter where you start with the negative wire
Customer: replied 11 months ago.
The charger has a seperate lead that was once attached to a battery, should this be to a + or - post and does it matter which one
Expert:  George H. replied 11 months ago.

It does not matter where you start as long as the batteries are connected end to end and not positive to positive. You want a chain so first battery is 8V then you add the next to get 16V then 24V and so on till they add up to 48 volts going 8 volts at a time. The sensing wire for the charger connects to the onboard controller. IT comes from the controller to the charger

Customer: replied 11 months ago.
there is a wire with a ring clip on the end that comes out of the main wiring loom. This is what we thought was for the battery charger, what else could it be for
Expert:  George H. replied 11 months ago.

If you had a wire from the charger to the battery and it is not one of the heavy charging cables it sounds like the sensing wire from the controller was bypassed. That wire can connect to the same post the cart negative wire is connected to. That is the last battery on the negative end of the string and you connect to the post on the negative terminal.

With the controller bypassed in this way the charger will run all the time it is connected to shore power and can overcharge the batteries. You have to monitor for full charge and disconnect when full. A full charge on a 48 volt rack of batteries is 50.5 volts. You should have a charge gauge that will tell you if it is fully charged if you disconnect the power cord and wait 5 minutes.
