So, my question regarding these style BMS, when they detect that a cell is in trouble, say a cell in a pack fails, and they protect they do they're safety thing of disconnecting, are they resetteable, kinda like a shunt trip switch is for the batrium setup?. I'm considering using these with the...

Sent you a pm

I don't get any better I'm afraid, and I'm based in Ipswich also, seq,

Those cells, still wrapped in blue shrink wrap, any idea what the chemistry is, I found a pack of them, 10 in the pack, absolutely no markings on them at all, even after stripping the wrap off the dead one. Varying voltages on the other 9, from 1.2v up to 3.9v.

Haha, actually I just reread what I wrote, and it didn't make much sense to me either, you have however answered the question I was trying to ask, thankyou.

Quick question, and it may have been asked, but I can't find it, lol, how do your pipe busbars handle the extra current it brings form adding more packs, is it not an issue because its corresponding next pack in the series is connected right beside it??, Or have u notices some of theipes getting...

Ok my bad, my initial calculations were off just a tad, as I'm aiming for 50 pouch packs per cell, so my secondary calculations work out to be pretty close or even just over a 10kwh group of usable storage, as I will only using the range between 3.15v and 4.05v in an effort to maximise cycles...

Ok, final report is in on the lipo packs, after taking approximately 16 hrs to charge at 1a from 3.8v to 4.2v , it then took approx 6 hrs in the opus on the discharge cycle, where they have come up with capacities of 5339mah, and 5328mah.....just another approx 300odd cells of these and there is...

Moli IBR-18650B, once again out of a drill pack, and again only 1500mah new, but, more knowledge for everyone else. Data sheet attached again, Note: Thanks, but can you try to grab some higher quality pictures please?

Haha, that is because those storage boxes are not completely flat surfaced inside, they have the occasional ridge, or set of ridges on the inside as the also come with dividers, but I don't need em, so they're back in my father in-laws stuff In the shipping container, boxes were his originally...

Inr 18650-15k Samsung's, data sheet also included, , capacity too low for me but eh, Out of an old drill pack Note: Thanks, but can you try to grab some higher quality pictures please?

OK. The fan on the opus like that is not blowing down on the cells, it is in fact drawing up through , but I'm working on trying to get a new base printed for it, where the fan goes inside, and as for how long till I use my cells, sorry must of missed it in initial post but 9week holiday is in...

OK, so, I have finally had an hr or 2 where I have been able to sit down and dismantle 1 if these packs. And do a little research on the cells, upon release from the their setup, the initial release voltage was 3.80v, so they are obviously not lifepo4. I have been able to attack dbl ended...

Or, your other option is say for example I am building a 14s120p, trick is on first string u build 15 packs of 120 cells, the 15th pack doesn't actually go into the build, but kept for a quick, "hot swap" if u will if u need to pull one for maintenance. Now I will also be sticking with 14s120p...

Ok I have a question about how to get my 18650 cells to storage voltage, or 3.7v after testing, I have my tp bulk charge board, Then I only have 1 opus ATM for capacity testing ( I could really do with another 1 or 2 if anyone has a spare they wouldn't mind parting with.....cheaply, lol)...

I was having the experience where every single one of my red Sony's that had an initial pack freedom voltage of below 3.1v got hot at 3.8v, where as the ones that started above that, 98% charged just fine, so got to thinking, and then decided to seperate my Sony's out even further for some...

They're good for 6 cells, not so much for 1000 cells, or more

Yep, quick rub with a green soft scourer sponge, and its all clean copper, so I'll get em in place, then clean the surface to be soldered and were all rolling lol, thanks for the knowledge

That's what I'm finding, its only, extrenal , cosmetic colouring, still copper colour inside when I cut it, cheers

OK, so I will be doing my busbars very very similar glublux, (just love everything about it), and I have come across, in my father in-laws old collection, since he has retired due to poor health, I got everything in a shipping container at my place, but in that collection, I have found a roll of...
