The SR500 really woke the little 36v cart up - Lots of torque increase but speed was about the same, maybe a little faster..... but no surprise, that is to be expected for a series cart cotnroller upgrade
Now I've added 1 more 6v batteries for a total of 6/7v and 42v. Finished out the new 2g cable set and charging. 42v will give it a few more mph and more hill slurping torque. NICE
