I am working on a E-Kart, it's a racing Go-Kart converted to a Electric Kart.
My setup is the following: Alltrax Controller(7245) and a D & D Motor(ES-15-6).
Batteries: 20P24S A123 26650 taken from Dewalt's A123 outputting 79.2V nominal and should be able to take a total draw amperage of 1400amps.
My problems:
My batteries are connected in parallel with 1/8" X 3/4" steel flat bar and springs carefully screwed to the flat bars and aligned to the batteries. Springs are rated at 100V 40A and I should only be pulling a max of 20amps per cell anyways.
Pictures of the strings and batteries: http://img42.imageshack.us/g/picture144c.jpg/
Problem 1: When I am pulling about 150amps, which should be nothing for 20 cells(7.5A per cells) my voltage sags to 58V(2.41V per string).
What am I doing wrong here? I need your help badly.
P.S: Whoever helps me find my problem will receive a donation.
Thank you and Greetings, Sly
