An issue with cheap, low capacity packs is that they will not be able to supply the continuous and peak currents required in a cart. The 60Ah battery linked to in the first post can only supply 60A continuously or 120A for a brief period. Definitely not enough.

Also, spending the money on a 25 year old cart is a non issue. Putting a lithium pack in a DS will transform the cart and give it a new lease of life. The performance increase will suprise you. And as has been said, it can always be transferred in to a new cart if you wish.

I would look for something with a min. of 100AH if I was to go to lithium.

I've been very happy with my 105ah....I also went back and forth about the additional cost. Now I wished I had done it a long time ago.

i use the cart about 10 miles per week so a lot of your suggestions seem like massive overkill for me.

You probably don't need the range of a 100AH battery but you might need the current capability. What Pat911 said!

Another point to consider is that a larger capacity pack will need less charge cycles during its service life to cover the same distance. Lithium battery service life is directly related to charge cycles so all things being equal, a 120Ah pack will have a service life twice as long than a 60Ah.

I use Chevy Volt cells for my cart and my buddies Taylor Dunn cart.

But there are many more versions of traction packs available now, each with their advantages and disadvantages.

On the online auction site I just found Honda Fit modules, LTO 24S 64.8v 20ah packs for $330. for a 51.3v max pack that'd be 19s so if you get three of those LTO packs you'd have 72 cells and use 57 for a 60AH pack and have enough left over to create a 60ah 13.5v pack for your onboard electronics.

There's Fiat 500e packs available for $300. Those are 64ah cells stuffed 6 in a pack. three of those packs would provide enough cells for a 51.8v pack at 64ah and a 64ah 14.8v pack for your electronics.

There are 64ah BMW cells that'd be an interesting upgrade for a 36v cart since they come as a 44.4v pack. These are the same as the Fiat if I remember correctly. Could be a pain to reconfigure though.

Also Ford C-Max cells available. I saw the 25ah cells (there are other smaller capacity cells too, so be careful) available for $425 for 21 of them. This would be a little more $ to build a pack than the other options but they are easily configured since each cell is separate with studs built on each end. Could be worth offering to buy two packs from them which would let you build a 14S3P pack for 75ah at 58v. They may accept $375 each.

The point is there are a LOT more options today than when I put lithium in my cart a little over 3 years ago. The LTO cells available are interesting but I don't know enough about them yet. If I were doing another lithium cart (which I am not) then I'd look into those a bit more... $0.02
