Lithium Battery Pack
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. Link to the connectors. http://www.mouser.com/ds/2/22/AT-CPC(1)-707509.pdf Page 3 Dual Pole Male and Female. Ill post more when the pack arrives, and I get it installed. Im in the middle of the overhaul, so nows as good a time as any to do it. |

Re: Lithium Battery Pack
The easiest thing to do would be just run #2 cables directly from the battery pack to the controller to test first, then run #4 cables and see if there is a difference. I have a 45v pack (6 modules instead of 7) and have logged over 250amps. I have the 400amp Alltrax controller.
BTW, is that a Titan body? I just ordered an orange one. |

Re: Lithium Battery Pack
Pictured is what your new battery tray might look like. The second one is with the pack installed. I did this for a friend. Write up on this site.
This cart has the XCT400 PDS and PQ Bandit upgrade on D&D motor. Will spin the tires on pavement. You probably won't see much above a 325A draw from the pack because you lost so much weight from the cart. Even when you do, it is for less than a second. I actually had Nick from EV in my cart testng it here in Orlando last year. He was surprised and initially concerned when I hit 325A, but then realized it was for less than a second at high amps. The last attachment is an excerpt from my monitor log on a full bore run on a 5° hill up to the house. This is the Executioner from PQ. Note the short length of time before the current drops to 140ish. And I have a high speed 10.3 transaxle vs your 12.44. |

Did you ask them to double up the bus bars? That is another place where the battery exceeds the "infrastructure". I have that exact same battery and am in the middle of the install along with an Alltrax. I just got everything laid out today and will begin cutting and drilling next week after I get back in town. |

Re: Lithium Battery Pack
Is it ok to ask how much the whole package cost?. I'm thinking about doing one and I have no Ideal as to cost.
Thanks Sonny |

Re: Lithium Battery Pack
hawmarine: I suggest you keep the Anderson connector. Whenever you need to work on the cart and need to disconnect power, it is very convenient to just flip the tow switch and unplug the pack. I have installed 8 of these packs, one in my cart and in seven member carts at my club and all of them have the Anderson conn. Remember that the rating is for continous current. You shouldn't have anywhere near 175 continuous, unless you do a lot of hill climbing with a loaded cart. We don't do that here in Orlando, climb hills.
I have installed two of those Double Take Vortex bodies on the Yamaha Drive. They have been very easy installs. Be sure and check all the edges, I learned to do some slight sanding on some sharp edges: fender wells, light openings, under front lip after the first install. Stops those nasty little razor cuts.
