So, I've done way too much marine electrical to make an ID ten Tee mistake like this:
Installed 2 new 206Ah SOK batteries and wiring. Had issues with the auto reset breaker (not a fan anyway) so swapped it for switch rated marine breaker. That was the dumb part - swapped at same 50A even though I knew the PD converter (with lithium charge profile) could output 75A and likely would with LiFePO4 batteries that will happily eat that up. New breaker tripped too whenever on shorepower and converter started charging. 80A breaker due here tomorrow...
