The 3 fet boards in big nipper, are set around 120 Amps (ish) but for some reason the weapon one (Still on CIM2 motor) causes the motor to cut in and out when on the current limit. This did happen on one of the MAGs also but we increased the current limit (dont know what it is now) and the problem went away.

We set this by stalling the motors and measuring the current! No stalling it for more than a few seconds at a time. At least the fet boards have a small LED that lights when you hit the current limit.

I doubt Dogsbollox will current limit the LEMS to any reasonalble level, as they use a hall-effect type curent pickup on the battery +ve which I assume will have a relitatively long delay before the current limit kicks in, due to this and the LEMS low inductance, basically I cant see the current limit working without a choke, but a choke might still be the simplest solution.
