What type lithium would I need?
 
I have been reading a bunch of threads on this but haven’t come up with the answer.

I currently run a 48 volt club car ds with fsip controller from Scottyb and a torque motor from plum quick. My cart is lifted 4 inches and has 22 inch tires. I am running eight six volts with two in the bag well. I hunt from it so it sees some hills, mud etc. it’s been a great set up but the lead acids are finally running down after five years.

My question is what would I need in lithium to get a comparable run time?

I’ve seen these for sale https://www.ebay.com/itm/Lithium-Che...400?nav=SEARCH

But at only 50ah would I need two?

If I got two what else would I need besides this set? Thanks

That would be Al and he is a Lithium Guru, BUT, he is all about the Chevy Volt's. I have one in my nephews cart and it works great. We only have one (50a/h and 3500 or 3750 watts) and it does fine for his operations around neighborhoods and parks. If you are out for long periods or extended high amp durations, you may want 2 packs, but one works fine in his.

The biggest bang with the Volt batteries from him is they are all new and never used. He is technically strong, and will not steer you wrong, but again, his is only for a Volt and not for Leafs or anything else.

Thanks for the response. What set up did he have before the conversion and how does it compare? I’m not interested in more power or more speed. My concern is run time.

How do you know if used one is any good?

It really is determined by the usage of it.... 80,000+ would scare me....:shock:

At 39k I would want to know the load test and a/h results.....

It's somewhat of a crap shoot but you should at least get the vehicle history. Most of the EV batteries are not available to us new.

So am I better off with a new Chevy volt battery with a bms? Looks like I would need two of those. Also this leaf system doesn’t have a bms which I guess I would have to buy??

I personally like the Leaf modules better than Volt but I have not used the Volt modules. You can build up your own leaf system quite easily as the modules are very easy to work with. One problem with Volt is that you can't easily separate the modules from each other. Adding a BMS is not difficult. I don't recommend lithium to anyone that doesn't have some knowledge of lithium battery handling - charging, discharging, etc.

Either pack (Leaf or Volt) will serve you well. It is more what you are looking for and cost/availability at that time.

A BMS is good to have. I know there are those that will sell with out it, and some that do not run one, but I believe they are essential to a long "balanced" life for the pack....

Re: What type lithium would I need?
 
I would not run without a BMS for battery life and charging safety reasons. Even though your charger should not overcharge the pack if it does you can have a disaster on your hands. The BMS gives you that extra safety during charging by monitoring every cell in the battery and opening up the charge circuit through a relay if any start to be over charged. Charging takes long enough that you can't stand there and monitor things.
