Size of battery cable

stellix

I am trying to figure out what size cable is on my newly refurbished cart. It has all new cables on it and they have the number 2 on the cable .Are they 2 gauge or would they be marked 2/0 to be 2 gauge. I didnt want to order an upgrade cable set if they are already big enough. thanks

Sounds like you have 2g already.
2/0 is double 0 which is 8Xs bigger

stellix

Thanks,is that big enough for an Alltrax dcx400 controller

scottyb

Yes, big enough for that and more.

stellix

Great,I'll be calling you soon to order my goodies

I looked at all my cables today, all of them are 2 gauge fine strand welding cable except the two long ones going to the motor. They are 4 gauge,would i notice any performance increase changing those two cables over to 2 gauge?

Solenoids

Indeed you will, if you are using it to the limit of the 4 gauge. I believe the entire power system (definitely including the cables) is only as good as the weakest, or in this case the narrowest, link.

The only reason to not change the those 2 cables is if it's a Ezgo PDS cart. The 2 smaller cables to the motor don't have to be swapped out to see max flow.
If it's a series cart then yes swap them.

It is a PDS. I'm planning on upgrading to an Alltrax controller soon. it already has the bigger cables and a bigger solenoid on it now. I added a factory EZGO 4" lift and 20" tires . should i go with a 400 amp controller or a 500 amp ? I want to use the stock motor as long as i can , but need to gain some torque .I plan on ordering whatever i need fom ScottyB in a week or two.

Im ready to order my controller,will a dcx 400 give me a noticable increase in torque? will it run run time by much?
