Been following DIY Perks for a while now, and he recently just dropped this.
I haven’t been following battery building here very actively, but this does seem to line up with what I’ve noticed being said.
His presentation is always really high quality, but I’m curious what more experienced builders here might have to add.
Been following him for a while too. Pretty good video, he pointed out some of the things that I mentioned in my battery video as well.
Also can we just take a moment to think about the fact that he made a 12s8p battery bank out of p42a’s lmao - also, APEX BMS, kinda neat lol
That’s crazy
As for the quality, he didn’t use fishpaper rings and his welds look scary but it’s not a kweld and the lighting accentuates the color differences, but it’s not in a board so not the end of the world
His series connections are kind of weird too
With all the finishing work, it seems like a pretty solid box though, very cool, I like it.
Haha yeah his audience is pretty large, although I kind of doubt many people will actually build this specific product, it’s pretty cool that he gave that exposure
I would assume its faster for him to order it from you than LLT
I would have expected him to use Tesla cells because it’s a much catchier thumbnail, but also given he’s so very much limited by the power electronics rather than the output of the cells it makes much more sense to aim for capacity than powerful stuff like a p42a
Edit: as usual take my stuff with a pinch of salt. Also he doesn’t really seem like he’s super focused on piggybacking on brands or trends for clicks, but y’know gotta get the money somehow
I didn’t see what thickness strip he used, but usually, the welds are not the restriction. It looked to me like 0.2x10mm. I think someone mentioned on the forum here that it’s about 5a of current transfer per weld spot. So if he did four weld spots per cell, which is two welds essentially, you’d have 20a of transfer.
He did 6-8 on most so that’s definitely not a bottleneck.
Pretty much every project he has done are on point, modern looking, simplistic and not much of an eyesore
This but it’s probably normal with the spot welder he used it’s more a mix of time and current, lower current that what a kweld could use so it need a couple of seconds to have a proper weld
