FCSP refuses to charge at set amperage

[BSull]

Progress! I turned off FCSP again waited a few then back on, turned off scheduled charge times in truck then waited 15 minutes and plugged in. Charge started immediately and climbed to 16.5-16.6kW after a few minutes (about 69A) and stabilized still not at 80. I'll check lugs inside disconnect and FCSP to make sure torque is correct and yes I'll turn off at breaker. I'll check voltage at FCSP and disconnect after checking torque. Probably not today, my inch lb. torque wrench hasn't been calibrated in years but I know where I can borrow one for tomorrow.

Awesome, I've never gotten higher than 77 amps.
I've seen rate taper off at high SOC's not sure that's impacting your situation.
It might still be off calibration a bit.

Yep, anytime I've tried to change the amperage via software on the FCSP, I then would have to reboot it twice (via breaker) to get the new setting to stick. Lovely firmware.

State of charge right now is 76, that might be part of it. I'll get it lower before proceeding.
