Help with battery pack config

[iangreenhalgh]

Hi folks

I have 100 18650 cells to build a 10s10p 36V 20A pack.

However, they are not all the same make and model of cell so I'm wondering how best to configure them - by make/model or mix em up so each bank has a variety of different models.

I have:

20x Samsung 22E 2200mAh Green
51x Samsung 26F 2600mAh Pink
8x Panasonic 2600mAh Pink
9x Sanyo 2600mAh Orange
9x LG 2600mAh Grey
1x Red Sanyo 2600mAh
2x Green 2600mAh probably Sanyo

45 of the Samsung 26Fs are new, unused, the 20 Samsung 22Es are new old stock, unused, the others all came out of laptop battery packs and are most likely unused as they tested close to their nominal capacity.

So should I config them with banks made up of the same cell e,g, 10x Samsung 26F or should I mix them all up?

I'd start with 10x2 22E's and 10x6 26F's for 10s8p. I'm not sure I'd even use the others in the mix, but if i did, I'd spread them as evenly as possible across the 10s.
