Ok guys now I know that I should have a better grasp on this stuff by now, but I’m still trying to figure these battery ratings out and how they relate to my expected range, so here goes. My pack is made up or the crown GC 225 ( which by the way I’m very happy with they don’t gas much and I’ve found no weak cells!) their rating is 20ah 225, 5ah 175 with a RC of 115 minutes at 75amp. So if the RC =143 amps and if I’m toolin down the road drawing around 100 amps could I expect around 100 minutes running time, conversely if I’m drawing 200 amps could I expect 50 minutes, 300 amps =25 minutes ect? I know that there exist an inverse proportion between current draw and current availability with the traction pack but I just can’t seem to get it. Major, if your there be gentle not all of us are engineers! By the way I did move my ampmeter shunt to the batt. Side and it doesn’t spike at takeoff anymore but I still tend to draw between 100-200 amps with gentle acceleration and speed. Any help?
