The battery builders club

…it was a 2021 post, sooo, if the Rona didn’t get him and the batteries didn’t burn him up, then I’ll pipe down.

I think it’s criminal that no other commenters said anything.

Quoting my goddamn selfie here, if forums on my tiny phone screen is more amusing than zucks big dick 3d meta energy, and I haven’t looked back at that thing yet, then I’m returning the 300$ head gear nonsense.

Zuck, actually get me wet in reality then we can talk, esse.

More likely are those Ah (capacity) I think.

If that’s capacity, the cells are fucked anyway :sweat_smile:

Old mate needs a somebody to set him straight

Yeah. Or maybe those are fake 30Qs, then he could be ok. :smiley:

Board and battery are built and he’s riding it around. Let’s play the fire lottery!

That’s kinda rude

Did you see those cell voltages?

Jk they’re capacities (but that’s also bad) I think that would be worse than voltages, either way, I wouldn’t use those cells

Any time you use reclaimed its a fire lottery but if done right it works just fine

Yeah, hopefully things balance for him

Agreed. By the time you’re down to 2/3 capacity (like those cells) you’re probably below 1/2 of the run time (energy).

Just curious, why?

What for? The LLT is more than enough to keep the cells balanced. Nobody knows how they would behave together, because it’s a stupid idea. If you have a really out of balance pack just use the balancer board first and then switch to the LLT. Or just leave it for a week on the LLT.

Hey, what kind of nickel strips are you guys using that are wide enough to fold over? Most of the ones ive seen are way too narrow for that

25mm wide for single stack 18650, 30mm wide for single stack 21700, 45mm for double stack 18650, 50 for ds 21700

Where are you purchasing 50mm from? It seems like a pita to find

Lots of stuff has a higher energy density than TNT, it’s not immediately obvious but what makes TNT special isn’t actually total energy at all. It’s how quickly it can release it, ie the instantaneous power. Gasoline is several times higher than TNT in energy density, and is plenty fast at releasing it, but not in the same league as a proper explosive

Alibaba/aliexpress. They cut nickel to whatever size you want. There are some people in the US too, but they were running out when I was buying some last week

That’s because there is no oxygen supply in gasoline. If there were, you could make it explode. That’s the exact method used for many IEDs main components, diesel and fertilizers.

Well the LLT doesn’t do active balance right? I wanted to add active balancing to keep things forcefully balanced.
