Thanks, it seems weird for sure. What did it do exactly when it "cut out"? Did the green light stay on, eg ? It worked again later, so how did you get it going again?
Are you sure it was the converter that "cut out"? I wonder if the BMS for some unknown reason isolated the battery, if it would look like what you saw.
Is there a re-setting DC breaker between the converter and battery that was "cutting out"? They can trip at lower amps than they are rated for, as was mentioned in another thread here recently. That would explain why it works ok at lower amps?
You might try the spare converter on the other battery your son-in-law has to see if it does the same thing. That would be very good info either way.
PowerMax and Lion might have to get together on this to solve it if the other battery and converter do it too.
