Default Re: Upgrading Controller and Motor

Thanks to this thread, I just ordered the 4ga complete wire kit for my 2004 DS IQ from East Coast Carts via ebay. With Bing cash back, and FL sales tax, it was under $100 for the color coded kit.

I weighed the option of the 2ga for $30 more, but after talking with Robby at Plum Quick motors and thinking about what controller I'd probably end up with, i decided the 4ga would be suffient and probably easier to work with. When I have my motor reworked later by Plum Quick for speed and torque, I'll probably end up with a 400 or 500 amp alltrax controller, and they felt 4ga was enough for my uses, which are mostly road driving with some small hills, some trail rides and occassionally 4 people.

Not sure if that is helpful to anyone, but wanted to share how this thread has helped me in my battery cable decision. Thanks.

Bringing 1 new battery into a old pack will cause the new battery to age faster, and cause the older batteries to get less than a full charge in the beginning.
The only way to determin the real difference is under load ,or check the specific gravity in each cell 1 hour after charge completes.

How old (date month) are the old ones, How New is the new one.

There are no dates to be found on them. The little punch outs have not been punched on the 5 Inter-state batteries and there is nothing on the one Trojan. I went by what I was told by the previous owner,,,,,,,, yea I know what you're going to say but if you consider what I had invested, out of pocket, in the items I traded for the cart,,, you'd see that I would have done the deal even if it had no batteries at all. That's why I don't mind spending the time and money to put it in top condition,,,,, I just want to do it the right way .

Check for stamps on the POS and Neg leads , on the batteries this is how Trogan date codes theirs.

The Inter-state batteries have an 8 B with a Z underneath it and the Trojan has an L5 stamped on it.

OK interstate = http://www.batteries-faq.com/activek...?questionid=53
= Feb 2008

Trojan the First is month = L = 12 or December ,
the second is year = 5 = 2005 (so December = 5 year old)

If he had a dead cell in interstate he put in a used trojan !

Since the interstate batteries are only 2 years old, would it be better to replace the Trojan with another new interstate or new Trojan or am I pretty much left with a dying set of batteries that will eat themselves up early? Do you think that because the interstate battery that is wired in series with that Trojan, and has a cell with a low water level, means anything other that it might just be another bad battery? It doesn't seem to me that things are right if there has been one or maybe two batteries less than two years old would go bad unless it's a problem with Inter-state. But to be honest,,, I don't have any idea as to how the cart was maintained in the past.

I've ordered a full set of 4ga. cables to replace the 6ga. anyway, because I figured that shouldn't do anything but help.

Before you replace anything I would do 2 tests. Start with a full charge and measure each battery for voltage with a digital meter then do a specific gravity test and post all the results.
If you don't have a voltmeter and need something cheap to do the job, Harbor Freight has them for about $5: http://www.harborfreight.com/cpi/cta...emnumber=90899



Hydrometers can be had from Ace Hardware for about $6: http://www.acehardware.com/product/i...LAID=109343097



Here is a state of charge chart for your use:
