Onward rear springs with lithium pack
 

I'm going to install a Nissan Leaf pack soon and I just know I will have to do something about the rear springs once the cart is a few hundred pounds lighter. I think the stock HD rear springs are on the stiff side as it is. Any thoughts on what may be a viable option?

Would getting a set of non-HD stock springs probably do the trick? Since the gas carts are lighter, do they have lighter springs?

I must admit this lithium conversion has been more mentally challenging than I originally anticipated. Just trying to make a final decision on a BMS and charger setup has consumed countless hours of research over the last couple weeks and I still have not actually ordered one. I lust look at the batteries in the garage everyday and smile with excitement

Side note - With all of the Lithium related threads scattered all over the place, could the mods set up a designated lithium section/forum to keep it all together? With more and more people looking to do the conversion I think it would make it much easier to do the research necessary instead of just using the search.

Also, I heard somewhere that Alltrax is in the works of making a BMS. Does anyone have any info at all on it? When it may be available for sale? I emailed them asking and didn't get a response, surprisingly. Needless to say since I'm happy with the controller I imagine I'd be happy with their BMS.

Give Scotty a try, he should know. I'm still waiting for EV battery center to crank back up, but I'm not sure they ever will, so keep me posted on the Leaf pack and performance. :thumbup:

Does this look familiar. They are always slow about getting things released. This was posted in June on FB

I’m guessing that red piece is the BMS. If they have had a prototype since June I wonder why it hasn’t been released yet.

Instead of waiting any longer I think I’m going to pull the trigger on the BMS system from Zero Emission Vehicles Australia. They seem to have the most ascetically pleasing lcd monitor interface and are cheaper than the Orion Jr. Plus the guy was super helpful through emails explaining everything and my different options. I was really hoping for an Alltrax solution since I’m guessing t will interface with the controller but I really want to get this done so I can sell my batteries before they are a year old.

Hopefully I can come up with a solution for the springs. I even emailed the place I bought my cart from to see if they have any ideas. Since the gas cart is 300lb lighter I’m hoping those springs are different and will do the trick. I’m waiting to hear back. If they are the same, I can’t imagine how anyone drives them because the rear on my cart does not move at all over bumps unless there is two adults on the back seat.
