I have a few different packs available. It takes a $500 deposit to get one and reserve a build slot. Currently about 2 weeks out on build slots. All setups will come with the proper BMS and are fully wired. Those with DeltaQ chargers can send them to me for a lithium upgrade. Gems with Zivan or superchargers will need to get a new charger with Lithium profiles($395)They will all be tested on the bench, disassembled and shipped. Anyone is welcome to pick them up in person. The BMS are Bluetooth and will connect to your cell phone for detailed info and control( you can disable your Gem from your phone)
Standard plus voltage (81v), extended range, 2 module pack. Very easy install. Fits easily between frame rails underseat. Should also fit in place of 2 front batteries on early Gems. This pack will make your Gem much faster and reduce weight by over 300lbs. This is the lightest pack and easy to work with. On a 2014 e4 30 plus miles @35-38 mph. (20s,85ah)One available. $2,000
Mid voltage (Same battery as above but 2 more cells, 89v total). Extended range pack. This Mid voltage pack will give higher speeds, better acceleration and 10% more range. Consists of 3 modules. Slight harder install. Great battery.(22s,85ah) One available $2,200
High voltage (97v), mid range.I have sold a bunch of these. This is for the performance enthusiast. ( it is the voltage I run) Super fast, It will make a 5hp motor easily do 40mph. This is as hard as you can run a Gem. We have dozens of Gems at this voltage and they have responded and held up well. Slightly more total capacity then number 1, but a faster pack. 3 modules. Fits between frame rails and maybe upfront in an older Gem.(24s,74ah) one available. $2,000
Mid voltage, extended plus, range pack. This is the easiest of all batteries to install. It comes as one module, ready to go. Hook up your 2 battery cables and you are done. It is a big module(112lbs) but fits between the frame rails on 2005 and up gems. You will simply cut a piece of plywood that runs front to rear, and sits on top of the frame. Slide battery in from behind and screw it down.( did I mention it is 112lbs?) Do not know if it can be fit into an early Gem. This battery would also be great in an E6 or utility.Expect 40 mile or so range.(22s,95ah) 7 packs left. $2,500.
All of these will SIGNIFICANTLY outperform any Lead setup. These packs with a 5hp motor will easily outperform a lead battery with a 7.5hp Gem. Multiple owners were going to upgrade to 7.5hp motors but after installing these, kept their stock motors and saved $850! This is like adding a turbo.
