120A huh... hmm... I may to beef up my 5304 wires a bit more, like 10-gauge. I'll start with a 24s5p a123 setup, which can easily supply 120A. Should be fun.

I purposely steered away from the 4 pin for the reasons you quoted as well as the fact that I dont think an LED "fuel gauge" is useful in any way. I can see your point about using a throttle with a button but I dont want someone with an LED throttle plugging in and thinking it should work. I will stick to the 3 pin for now.
I was actually after the pinout for the eBrake.

The price of the caps wont be that much but the labor keeps increasing.
how many other people out there are actually running 24S lipo or equ?
Probably only 5 or 6 of us
I bet most people are running more like 70 - 80V tops.
If this is the case, we are set as is.
methods wrote:Right, but 24S A123 is only 80V nominal.
I think the original discussion was revolving around how Doc is pushing for 160V caps
I was arguing that 100V caps are plenty for most people, you included.
I am even running 24S Lipo on the 100V caps without issue (yet) and these are the caps from China.
You will get better performance with more capacitance at 100V than by bumping up to 160V and losing capacitance.
I agree with you though, no point making anything less than a monster.
I really dont think we need to worry though. I dont think anyone here (on a bike) can draw more current than this controller can handle.
If we get into the motorcycles... Then maybe we will hit some limitations - but my guess is that they will be practical limitations, - like wire gauge.
