UPDATE on 17 Nov, Update 2 on 22 Nov, Update 3 on 16 Jan 14, Update 4 on 19 Oct 14. --------------- In a recent thread there was mention of how you can wreck your gizmo (in my case a converter) ...

I have redundancy in having other chargers I can use until I repair this one again. If I have two in parallel, it was stated that reduces the R by half if they are sharing so that would be a negative if I have that right.
So the latest thinking must be that the 2R025 instead of the 5R 020 isn't such a good idea if the problem is all at start -up and I need more R and higher J?
I would still like something else for the newer design converter that has that bigger thermistor (which has the identity numbers part missing) than the 020.
Not much choice here.

The converter steady state while at 100a is supposed to be 13a or at least it is rated to use a 15a circuit, being PF corrected. There is a 10R 15a but I am dubious of that 15.
If there were a 10R 025 that would be nice.
But then what about the business where if you are sitting there on shore power for weeks at 13.6v and mention that the higher R could leave the thermistor doing a slow cook? Wait! Now I am muddled on where that NTC fits in with that. :(
