The benefits of reliability and a better torqued connection with the welded stud, outweighs the larger surface area of the drilled and tapped hole.
Only problem is one terminal is missing its threads.![]()
Lol. Yeah, tapped it, grub screw locktited in, it’s solid.
Why are these terminal screws so tiny? M6? They should be at least M8.
It takes the LF280N between 70-76 hours to parallel top balance with a 10amp power supply.Broke out the new power supply last night, installed all of the grub-screw terminals, hooked the cells up parallel, and put the charge on them, initially to 3.4V. They've been on for over 18 hours and have only gained about 2 tenths of a volt. LOL They started out drawing about 9A, now down to 5.
I'm doing the step method - to 3.4V and rest, then 3.5 and rest, then 3.6, call them balanced. I'm guessing the second and third steps will go quicker.
So far so good...

My guess is that these cells are designed are to be implemented in battery packs with fully welded connections/bus bars. I can’t imagine an industrial use of these cells would have any sort of threaded connection with such weak method.Why are these terminal screws so tiny? M6? They should be at least M8.

These studs or serviceable connections are an afterthought to unload cells on the DIY market
Again just my thought.
What is the largest cells Jenny or Docan can supply. i can't seem to find out. on Alibaba there site hints to 500, 450 ect but no direct info.
