Help a guy out?

GEM Forum

I am in need of some help. I have three GEMs; a 2000, 2002 and a 2009. I was hoping to repower at least two of them, so I purchased a Chevy Volt Gen. 2 battery pack and a QuiQ 1000. I know the 2009 has at least a DeltQ of some sort already. But not sure on shunts, magic magnets, etc.

I have been doing SO MUCH research on how to do this by reading all sorts of forums and watching YouTube and thought I am ready.

But I have a huge challenge hindering me, Chemo Brain. If you or someone you know have had cancer with chemotherapy, you know what I am going through. Just when I think I am ready to take this on……gone!

I am in need some help. I need some basic instructions on how to do this. As you may have seen, I ask some questions here and there but I need help putting it all together. Not physically, but with simple instructions. Has someone done a DIY post or video on this that I missed?

I had planned on going 96v but am reading going with 72v gives better range? Are shunts still a thing? Most of the post I have been reading about them are older. With a newer charger, do you still need a shunt to top off and balance the batteries? Where can I get the secret algorithms for the QuiQ chargers? I think I saw were someone has 96v but charge profile at 98v?

Could someone help a friend out?

Thanks!

I can answer questions, but I’m not a good teacher.
Keep it simple. If you don’t know about shunts, probably don’t need.
24 cells is the most we have used. 88 volts nominal. Safely charged to 96v.
What year do you consider Gen2? 2014-2015? 2016+ are configured differently, using 16s and 12s, rather than 12s and 6s.

Are you looking for more than 20 mile range? Then use a double set of modules.
2 x 12s in series = 88v 50ah ~20miles
4 x 12s connected series parallel = 88v 100ah ~double miles

Start by fitting the modules in the battery tray.

12s 44 volt module

6s 22v module is 1/2 as long
16s 58v module is similar but longer

The 2009 will be easier to convert , start with that one if you can . First thing is choose how many cells you are going to run . 20-24 is the range . If you can do 20 your install will be easier . Now you need a BMS . This is the hardest part . You need to pick one (i’m not the expert on these ) and wire it to your battery . Once done install battery . You cant get the lithium algorithms . Deltaq protects them . Inwo and are are not allowed to share them or we lose our support from them . We paid thousands to get setup and I charge $75 to add lithium profiles . If you do 20 or 21 cells you are good to go .
