Hi-
I have just installed the GE sentry software and would like to reprogram my 2014 GEM e4 to up the top speed to the 35 mph range
any tips on the settings?
thanks
Rich

suesamh… is your e580 a 48v car? sounds like one or more of your batteries are not charging all the way… charge your car and check the voltage of each battery… each should be about 13.2 when fully charged… if one is less it probably is pulling the pack down

I looked for the video and it’s no longer available. Do you still have the heatsink set up? any pictures available? or the video? Has the 5 hp held up with the added power allowance? Thanks in advance!
