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
Not as bright orange as I thought. Maybe it's just the picture?

Re: Lithium Battery Pack
It's got a protective opaque film on it. I thought the same thing when I first saw it.

Re: Lithium Battery Pack
Yep! I bought the 350A version and the crimper on Amazon and when it arrived, I had to hit myself for not being so bright when I saw it all in front of me. Thank God for Prime and being able to return stuff easily!
After talking to a few people here and to Nick at EV, the highest load from the cart is very brief. When they do their testing, they said the battery could take 540A PEAK. I cannot remember how long but it was longer than I expected. The cart will hit peak current in the first few seconds from stop and last a brief amount of time. Running full throttle on flat ground, they were getting 60-70A. They also said their rating was 250A CONTINUOUS which was for 15 minutes! |

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 |
