I got the Kelly KBS72121X controller,
And i looks like its capable to handle 55A FASE current, not battery current.
Its only 26A battery current.
Yes, it can do 55A phase current continuous and 130A peak for 10sec, but what gives you the idea that this is only 26A batt?

motor current: 80%
130A * 0,8 = 104A phase
battery current: 50%
104A * 0,5 = 52A battery
if you set phase current to 100% than it's the 130A as specified.
batt amps can be only set to 70% from what i know, so 130A x 0,7 = 91A which would be about 8kW peak at max allowed voltage.
Not bad for such a small controller.
