These are the 3 different packs now available for Gems . I will try and keep them in stock as much as possible but there will be times that certain ones will not be available . All of these are new and recently manufactured .
1: Medium range pack : 24s 96v 74ah . The pack will consist of 3 modules with leads . The plugs will have an adapter on the end to connect the raw wires from BMS . You don’t have to do it this way , you can hard wire them or any combination that works for you . The main power terminal are 1/2" wide spade ends (pictures below ) You will have to decide how you want to connect these . I am hoping as more people install these we will see some different methods . These packs will significantly increase the performance of your Gem . It’s like you added a turbo . Hill climbing , top speed , acceleration all much better . Range will depend on your set up . Tires , speed , weight , hills etc. I would estimate low 20 mile range for hills and high speed . To 30+ miles flat ground and 30 mph . Packs weigh about 75 total for all 3 . These high voltage packs will require a LithiumGods particle splitter that will included with the packs . $1200
2: Extended range pack : 20s 82v 180ah . These will consist of 2 10s packs .The packs will be drilled and will have SS screws attached on each cell for the BMS wires . Cells will all be labeled to help simplify install . This pack will significantly increase range, 30 mph , level ground up to 60 miles is possible . Pack will also increase speed and acceleration . Not quite as much as the high voltage packs but MUCH better than a stock Gem . This is the most popular pack . Each module weighs 70 lbs for a total of 140 lbs . Packs come with threaded studs for easy attachment of battery cables . $2100
3: Extended Range - High Voltage packs: 24s 96v 180ah . These are the Top Dog packs . This is what I run (Gwest , Roman and a few others do too) . They combine the extend range and high voltage . These are for the Hot Rodders and individuals looking for Maximum range . This will make your Gem feel like you added a supercharger . And give you even a little more range than the extended pack . They consist of 3 8s modules ( same cells as the 10s modules , just less ) . They weigh about 56lbs each . Also come labeled , drilled and tapped and with battery terminal studs . Requires a particle splitter which is included . $2500
All of these will require a Deltaq charger to have Lithium algorithms installed . Other chargers may or may not be able to be reprogrammed . I keep New DeltaQ’s in stock set up for lithium .
All Lithium should have a BMS installed . They protect your battery and your Gem . You will need to order one directly from manufacture . Most people get them off Ebay . Price $125 -$200 . Hopefully others can share which BMS they use and how they like it .
Everyone one who has installed these have been very happy with them . They are new so they don’t have to worry about the condition of used lithium’s sold on the internet ( many sold as new though they haven’t been manufactured in years). Hopefully those running these cells can share their results .
Disclaimer : I don’t sell drop in lithium conversions . I sell batteries that can and have been used in Gems for DIY installs . Each individual is responsible for their own design and setup. They should properly educate themselves before attempting this . Gems use high voltage battery packs that can be dangerous .
The module on the left is #1 option . 74ah , takes 3 . center module is #3 8s 180ah , takes 3 . Right module #2 10s 180ah , takes 2 .
