.... - on better supplies the likes which Methods uses - probably no pop fuse, no blown fet, resettable breaker? LOL...

Hmmm. Are you sure you put it on correctly?
If you cant fix that you are weak-sauce.
I - personally - would spend the 36 hours it would take to repair/rebuild/reverse engineer all that.
150 / 36 = $4.16 / hour for your efforts!

Thanks for any fire alarms you can pull in advance,
(My wife made me write this after seeing lipo fires on youtube)

Now the bad news.
1 Came with a slight puff on an end cell, and one came with a cell at 1.0 volts.
What should I do? Charge and see what happens? Send em back?
