I’m mentioning here the people I’m interested in joining the first round of testing.
@rusins So I’d assume you’re interested, as we have already talked about the pack that you want, use case and used cells?
@tech.shit You’re interested in making a segmented underslung pack?
@Plurf a rigid one piece 12S1P pack with Molicel cells.
@yoyotinker Are looking for a rigid single segment pack?
@zero_ads Are you interested in joining? Segmented pack I’d guess?
@ShutterShock You seem interested, what kind of pack are you looking for?
I’ll start with the 6 above mentioned people, assuming they all want to participate. You can accept, reject or ask for more info in this thread. I’ll kick off the group PM soonish and add the confirmed participants there. I’ll share more detailed info about the pack construction there.
The pack I use is like the green one because it made more sens mecanically, but if the whole thing is already rigid and there’s no risk of short between the 1 adn the 12 both are fine for me,
I guess the red one save cable length
I’m interested, but I’ll have to pass I need an enclosure or to make one. And not sure when that’ll happen, so I wouldn’t be able to test any time soon. It’d be a weird config too 8x10 20s4p molicels with split groups involved.
I will have to get back to you tonight with specifics. If you are saying that it can work for underslung enclosures, I need to make a battery for my hummie still, do you think that is possible?
I’ll look at that tonight - and yeah that would be the goal. No idea if it will fit though. If it won’t, I’ll probably do a brick pack, whose dims and config I’ll get tonight too
That shouldn’t be a problem, for a single stack height.
But this is. The total length in the cells length direction with the pack structure is 76mm, so they won’t quite fit as 2 long straight stacks, side by side (shown below, not to scale).
So you already have your other electronics in there and there is 500mm of free space available for the battery?
5 segments should fit with 100mm reserved for each, so plenty of breathing room. It would fit 6 cells side by side, so it could make a total 15S2P pack, divided into 5 segments of 3S2P.
6 segments would be snug (83mm reserve, so ~8mm of space between packs), but should still fit, but there isn’t any reasonable configuration to make with that, unless it’s 12S3P, but I don’t know if that’s too low of a S-count for you?
Hmm. This is quite the predicament. SS makes this real tough. 15s2p is kind of pointless over 12s3p.
Yeah that’s what I meant. I left enough space leftover in the available space for the electronics, so I have ~500 for the battery.
I will probably skip this concept for the hummie haha I don’t wanna have to do some weird split thing with part in a top enclosure, so I’ll figure something else out
The 20mm space is for any connectors, bms, etc. I could alternatively put the bms on top of the pack and use up to 14mm of that space, so maximum space would be around 194 with top mounted bms.
Not sure how your balance wire routing works exactly
16s battery is what I’d be looking for in this space p groups maximized
