FAQ

I just had a brainwave. Or a brainfart. You decide! Big Grin

No one is doing YpXs anyway, right? Some people ask for it, but unless you have a very good reason you shouldn't do it. Since this is supposed to be for beginners, shouldn't we just say "Look, this is the notation for the specification of a battery and XsYp works like this: ..." and "You can do it the other way, but you shouldn't unless you have a reason."?

2p14s80p is even more correct, it also indicates the 2 strings of 14s80p are connected in parallel, 2*14s80p is not....  Some guy may put 2 strings of 14s80p in series heaven forbid, we cant have that Wink

If you want to stick to 4 packs, ok, but just do not change the color  Big Grin

Hahah, well, this is essentially true. However, there are a few who are doing the YpXs design.

I suppose I kind of am. I plan on making each pack 48V nominal. But I haven't decided if I wanted to do Xp14s, or make the pack 14sXp. It kind of all depends on how well I can build the bms hardware and how flexible I can make it.

The reason the color changed was because I imported someone elses 3D design of a cell. It's more of a glossy color. That's all Wink

I must admit, always thought 80p14s was 80 cells in parallel per pack, and then 14 of those in series.  Blush

LOL, If we can't agree, what chance has a poor noob got.  Rolleyes  Smile

Maybe we should have an aptitude test for new members, where they have to correctly answer which is which after reading the FAQ, before we let them in. Big Grin

- MPPT is Multi Point Power Tracking. This charger tracks along the voltage/current curves of the supplying generator (usually Solar Panels) to achieve the greatest

I thought it was Maximum Point Power Tracking.  Huh

Yeah it is really counterintuitive. That's why I would always use 14s80p for both configurations. Because that's what it is. But if I had to use both, then I would read those as what to do first and what to do second. And that means 14s80p is 14 cells in series, paralled 80 times. And 80p14s is the opposite, exactly as you thought it is. But instead real 80p14s rarely exists and 14s80p is what we would call 80p14s because this is the intuitive interpretation. However, obviously 14s80p can also be read as 14 serial packs of 80 parallel cells. So both ways are possible if logic is applied. But instead we apply a definition to something that tries to be descriptive. Small wonder that this doesn't work properly.

Apart from ignoring it and telling people they simply shouldn't do 80p14s I don't see a way around this at the moment.

Oh, and yes, the M in MPPT means Maximum. There is something like MPT, Multi Point Tracking, and MPMT, Multi Point Motion Tracking, but both aren't related to solar or even electricity.

Maximum Power Point Tracking. Yes, I was just throwing it out there. I don't use these so I didn't catch it right off hand. However, you all knew what I was referring to Wink

Ok, so, now onto another section of the FAQ. The pack building nominclature is still in debate, but let us focus on further down the line. We gotta get the FAQ done. There's gonna more and more noobs coming here now that Pete's been on the news, and several other main stream news sites have picked up on it.

Agreed. Just thinking what about a Wiki? Then anyone could contribute to it. It would be easy to read and easy to search. If you search this forum, you are likely to find many discussions that are not relevant to your scenario. (for want of better way to word that  Tongue)

That is true. I don't know the steps to making a Wiki. Never done it before. But it is a good idea. However, we want to make sure the information is as accurate as possible and don't want someone mucking it up cuz they got a bug up their butt, ya know? Wink

It is very easy to set up a Wiki. You could just allow a select number of users from this forum to make modifications. That way you wold be able to regulate it. Anyone makes a mess, kick them. There are plenty of us who know enough to help compile content.
