I am putting together a new performance lithium pack . Almost done with the mods but don’t have a gem that I can test in . My personal Gem has The extended range lithium pack in it now and it would be way to difficult to remove it for this testing . Also my available time is very limited at the moment and I want to get this pack installed in a Gem and tested ASAP .
I currently have big extended range packs available, they are the best battery packs for a Gem you can get . But they are over $2,000 and maybe more than some need . So I have been looking to put together a Setup that will give a Gem more range , Significantly increase its performance with a stock motor (eliminating the need to spend $800 on a Ride 4 Fun motor ) , and be easy to install . Plus want them to be NEW . Nothing wrong with the salvage cells but they can vary wildly depending on history . For an end user that is fine but not to sell . I also want to warranty them so the owner has a piece of mind installing them . All this and get the pricing under $1200 , Cheaper than a new set of Gels .
So the set is made up of 3 modules for a total 24 cells (24s) . Voltage range 84v-96v
The tester set is $900 .
So what i’m looking for is a " Scientific Pioneer " with a 2005+ Gem for this first install that can get it in and running asap . The plugs for the balance leads have been modified for easy splicing into a BMS or balancer . You will need to order one .
Also need to figure out how to connect the modules together for the main power cables (still scratching my head on this one ).
The info I am looking for is a comparison in performance to your current setup and range .
If this works as planned packs should be available in about 2 weeks . Might be able to get another one together for an additional tester (maybe pre 2005)
After testing if you are not completely happy with it I will refund your money so no risk on your part .
Upon successful completion of your mission you will receive a " scientific pioneer " limited addition badge .
Hi Mike,
I am up for it.
My GEM is an all stock 2001 E4 with 1600 miles on it. Currently has 3 years old AGM batteries. At the GEM dealer until tomorrow to install front disk brakes and a new DQ charger.
I wanted to try this on a 2005+ first . I know for sure the t3-t5 can handle the voltage but I don’t know about the T2’s and don’t want to delay the project . If I get a second pack are you up for doing this kind of work ?
That’s what I’m concerned about . I can eventually figure out the best setup for a pre 2005 but need some time . This one needs to go in a 2005+ with a DIY guy who can get it done quickly .
Mike, I have another 07 E4 I have to bring home and it needs a set of batteries so I’m game. I will be converting to AC next. So I can do both systems for data.
The Gem or the Battery pack? The Gem is ready to go. I had no room for it but I sold 2 Seadoos 2 trailers so I just need to go pick it up from the body shop
Modules finally came in . @Ljtoro is going to be getting a set in the next couple of days and help with getting them dialed in . I would like to get one more set out to someone who is ready to do an install and is up for a little challenge . Info from 3 testers should give us all the data needed . ( @Monkeyron also has a set is in the process of installing) https://photos.google.com/photo/AF1QipMnERFfPGkxJepkj0UPvE8YavfYJrJmmdK8a6Iu
