Upgrade 98 Series to 42v

[jasonnorton]

Just upgraded via ScottyB to an Alltrax SR48400 with 400 solenoid and a SW182-36v. My wires are all either 2g or 1g cable. I'm thinking of adding the 7th 6v battery (like in the install thread). How many folks run 42v, is there a downside, and is there any additional parts other than two more cables that I need to purchase?

You will also need a 42v charger. I personally would go to 48v in a series cart.

Six new batteries is much more expensive than one 6v. I can probably push one by the wifey
... Otherwise I'll have to wait until natural replacement time and my batteries look like they'll be fine for a while. I'll look at 42v chargers now...

Yep you are a candidate for 42v then, The DPI charger comes in 42v with the D plug to fit your cart... and you only need one 14" cable to add that 7th battery.

And yes, I know that's a red cable in the middle... But when the short cable grows legs and walks off, probably due to my 13year old... You adapt ;)

Thanks ScottyB. Is there any other downsides to 42v? I'm assuming I'll also need to update the programming on the Alltrax.

But 2 6v fit perfectly in the bag well!

That is a good point. I wonder if I need to do anything to the SW182 or is that another purchase? Seems like my options I'm looking at now are:

1. Go with Admiral Mot-A1 motor $435
2. Go with 1 6v battery and 42v charger $408
3. Go with 2 6v battery and 48v charger $521 (and possibly another reversing contactor purchase)

All pretty close in price. Probably my final golf cart purchase until 2019.

From the looks of your batteries, you DON'T want to add one or two new batteries. Used is what you want, for now.

Thanks Yurtle. They seem to hold charge well. After charging 100% and letting sit a day without use they still stay above 38.20. But I'm definitely a fan of used prices!
