next update...
Well I purchase the two extra modules and reconfigured the batteries in a
12S6P configuration, i.e. 50V at 180Ah.
I reset the throttle back to original (100%) and let it rip. Yikes it still moves like a scalded cat, barks the tires on asphalt pavement...
.
So I ended up settling of 75% for FWD throttle and 30% reverse throttle.
GPS max speed is ~19mph which is good, and throttle is nice w/o and controlled being crazy jerky.
I attached the log file for those that want to look at the results.
Now to see how many miles I can go on a charge, (thinking 50+)
