So I ended up pulling the trigger on the 54V (48V) 3200Wh Battery Pack from EV Battery. I called and talked to them before ordering. Was very hard to understand them but I had some questions in regards to the Maximum Amps the pack would put out. I have a 500AMP system, as I upgraded everything on the cart with the kit from ScottyB. The documentation on EVBattery website showed a max of 300Amp, with a sustained output of 175Amp. After talking to them, what I gathered from what I could understand, they were saying that is due to the limits of the Anderson connector being only a 175Amp connector, and #4 wire.
So I've ordered the pack with just a charger connector on it. I have since sourced #2 welding wire, some Anderson connectors rated to 600AMP, and the crimpers to put it all together. I had a hell of a time finding the Anderson connectors for sale, since you have to buy everything separately, they don't sell a whole kit. So now ill make two cables one with a male, and one with a female end, and have one cable for the distributor side hook up, and one for the battery side hook up.
I think this should get me what im looking for but im not really sure. Guess we will find out.
