See any of these?

I am finding that the soft-pack cells of similar shape and size to these are becoming more and more prevalent. Many of the newer Dell packs have 6 cells, in pairs of 3 different sizes.

I am likely going to be building 14s packs, maybe with self-balancing capability, and this _should_ allow me to use cells of any size, using one cell type per pack.

Something like what you have done here would be perfect. All I need to do is work out how to fix my 3D printer...

Hmmm... self-balancing ? intrigued ... :)
Has to be explained, withdrawings,videos and essays .... can we have some ?? please :p
 
Ah,Brians Equaliser ... ok, already explained, so no need for a essay on that one.
Maybe a video on what"flying" means in California ? :D
 
Perhaps we can use the more technical name of TDM cell balancer (time domain multiplexed cell balancer). He ought to file a patent for it unless someone has beat him to it... I don't know if it's different enough from a switched capacitor balancer design to qualify.
 
Anyway.... getting back to the original topic, someone mentioned a data sheet for these cells. While I cannot help in this case, I did come across a spreadsheet for Coslight cells.

While it has many cells listed, I have many that are not included, so I did a little analysis of the volume of each cell in the list vs the stated capacity, and came up with an average that I use to 'guesstimate' the capacity of the cells I come across.
