Someone else (I forget now) did some testing on this. It's worth a try.
You'll just hit the current limit faster when you nail the throttle.

That sounds like the easiest way, except I gather from what others have said here, that will make my CycleAnalyst's current readings inaccurate. Is that not the case?bobmcree said:it is much simpler to change the shunt resistance than any other method, either by adding solder to connect two of the shunt conductors together for part of its length or by soldering a piece of wire between battery minus and the minus of the big caps. ...
Thanks Bob. That sounds good. But won't modifying the shunt with solder or whatever make it nonlinear? Or will calibrating to the middle of the range be good enough?bobmcree said:... alternately, if you have a good ammeter you want to use for transfer of calibration, compare the cycle analyst readings with those it provides, and scale the default shunt value of .001 ohms by the reciprocal of the ratio you measure to correct the readings.

Pic and instructions for 20A version. The other Fechter knows the board layout :lol:
