IMO almost anything will not fail with only cold starts as long as steady state can do over 13a. We'll see.
I do have some 2R025s and some 5R020s on hand to keep things going, now I am an expert at replacing thermistors with my handy-dandy 3/64 drill bit and cheapo soldering gun.
The trouble is, you can't prove a negative, so if nothing breaks from now on it proves nothing whether a different thermistor would be better or worse. Also I am not clear on this, but it could be a******shoot just where you happen to be on the voltage sine wave cycle when you turn the unit on what stress the thermistor gets.
If we camp four days in a row each month needing the 100amper each day, till solar charging re-starts in April, beginning end Jan/early Feb, that would be say 12 recharges with 100ampers and then maybe a few in the summer, depending on cloudiness.
So it could be a year before anything goes wrong, or two years, or never, or the very first time out next February. IAW don't hold your breath waiting to see how this all comes out. :)
Don't forget I just did four days last month and the 100amper worked every day even with its broken 5R020 from the first hot restart event the first day. If I don't take the lid off and peek, I could go for a long time with a broken thermistor and never know it.
(Perhaps the low failure rate on these is due to that too, who can say? Could be lots of broken ones out there that still work so nobody knows they are broken, or maybe none of them is broken just mine :) There is no way to know. )
EDIT: I don't know why rv.net thinks that game of dice is a swear word, but it did a re-work on that all by itself in this post, so don't think I did it.
