Which RoyPow?

[simicrintz]

Really want to try and do the lithium battery in my cart (details are in my sig) and have a hook up that might make it "affordable". My question is which pack should I get? Club Car DS that has been completely stripped and is getting items in my sig added, including a new wiring harness.

I am really hoping to pull this off (I already have way too much into this cart so why stop now?!); thank you for any direction you can provide!

My only suggestion is to hold off on the Controller install until You decide on the lithium battery setup as it could affect how the Controller will be setup (Max current, Regen, etc).

Thank you, Sergio! Are you saying that I may not be able to use the controller I have (Curtis 126 or that I just need to decide if I am going lithium or not as it applies to the set up of the Curtis? Everything is still in boxes yet (I am waiting for a Spartan body and want it here before I start placing everything just to confirm clearances).

Any input on the unit? I suspect that I would want the S38105?

Sergio will give you a better answer but from what I have been reading ( I am interested in another build with lithium) is that the lithium batteries can’t handle huge amp draws off them as well as lead acid batteries. I don’t know much about the Curtis controllers but with an alltrax, for instance, you can control/adjust the max amp draws off the battery pack. On the positive side though you drop hundreds of lbs have longer run times and don’t have near the voltage drop that lead acids have. If you can get a deal get the highest Amp Hour pack you can afford.

If I was gonna drop the money I would, at a minimum go 48V, and get either the S51105 or ideally the S51160. They have the 72v option which could produce some insane speed but IMO it’s too much for a daily driver. With enough road I can cruise around 30mph and it’s plenty fast on a golf cart.

Thanks, Jake. I was semi set to run six 8's, so I was geared for 48V already but did not see that on the RoyPow page. I like the idea of less weight and no water, and in my pea brain I always figure if what I need costs X and what I want is X+, then the real cost is the +. If I really can figure out what I need to order and the delta is not that great (trouble is I get great prices on the FLA batteries also!) then I will grab the lithium.

Thank you again for your reply!

In addition to the pros of lithium mentioned I think you should get near double the life span vs. FLA. I think that in itself is a big sell on lithium's and it sounds like a lot of people are doing well with the RoyPows with not to many problems. I am a tinkerer by nature, an engineer, and while building a battery pack would be neat its not my expertise and the rest of the build I would rather do on my own. The lithium AC conversion will be my next cart, probably 18-20" tires with no lift (or lowered) for a fun adult go kart! I just gotta prep my wife and wallet for it haha!

I was wondering to myself earlier today if anyone ever bagged a golf cart :)

spoken like a true gearhead. do it! it's gotta be easy with the motor attached to the axle. thou the front axle might be tricky. if i was an asphalt cruiser only, my cart would have 1 inch clearance from the ground

Everything I own is geared for dirt (K5 Blazer, Jeepster, dirt bikes. 3 wheelers) and I have never had anything "lowered". I imagine that dropping a cart could be a lot of fun!
