Just finished a big performance upgrade on a clients beautiful 2022 e4, 5kw He had it shipped to me and said build like it was your own. Gem got our new 64v 310ah Gilath battery and one of Gabriel Reberte’s Speedbx’s. Gem performed well, nice increase in acceleration with the higher voltage battery and hit the target speed of 35mph. Great combo but I knew it was capable of more. First run to 35mph took 26 seconds on level ground, 1 person. Next I did one of our LithiumGods power reprogram. The Gem is capable of much better performance but has been heavily restricted by the factory to increase range. With the large lithium battery we don’t have to worry about range and can unleash the power that it is capable of. The Gem requires a good power source to reach its maximum potential and the 64v gives it that in a big way. The second run dropped to 11 seconds! This Gem now has Great acceleration. The difference is like a Kia to a Corvette. Lithium upgrade by itself is a little better than lead, but do it with higher voltage and a power program and it is just wow. This is probably the fastest stock component Gem in the country, it’s like Porsche built it. It shipped yesterday, looking forward to the client’s review when he gets it. Need to figure out how to upload video ---

My 2020 2e has Rodney’s upgraded tranny along with the OEM extended batteries. Readily gets to 34MPH but immediately stops increasing in speed upon the OEM speedo reaching 25MPH and invoking the “governor control” limitation. I get the feeling there’s another potential 1-2 MPH lurking in the background. Do you offer programming alternatives that would bypass the OEM limitations? ---

I cant do speed upgrades, just power reprograms. If it is hitting 25 on the speedo then you would need to talk with @gabriel about increasing it. he is the only one that can
