Errin says also they are looking at a new power centre, don't know what converter it would have.
I guess calling a converter an LFP one is just for the "Sales" people, since the LK model already can do any LFP spec plus any other type of battery's specs.
if you can answer the last set of questions and try out the other "set" of converter-battery, then Errin could read all about it here (a link to this thread by email) and do whatever needs to be done.
The converter has nothing in it that can cut out and cut back in that I know of. It has a 120v fuse. Other things in it can fry.
OTOH, the BMS can do that action I think. IMO the first thing is to find out if possible if it is the BMS doing it or not. If it is with the batt you have but not the other batt, then that might be a warranty item for that batt. Maybe that converter is duff, but the other other one is not.
#8 is too skinny for the 55 amper. Could be why only 50 amps. I use #4. #8 has the ampacity in theory but I had fewer amps with it, and good amps with the #4.
