Do i have this rite, mmm 2200 and lipo choice

I always thought the 'weaker' cell is weaker due to a higher internal resistance. Thus being paralleled with the stronger, lower resistance cell, the load would be distributed proportionally (ie stronger cell loaded up more). Otherwise the weak cell would be under as much load as the other, presumably stronger cells, in its battery.

I guess in the end if you have a weak cell, you have a weak cell. It's going to be stressed no matter how it's connected, best have it die young by itself in its own pack, rather than give an unfair load on one of the good cells and make it fail early...

Yeah, weak is weak. Maxamps do not match their cells, so that is why the paralleled (and other) packs have issues.

I just really prefer to parallel the cells outside of the pack. Makes it easier to keep tabs on all of the cells, and catch problems before they cause issues...

Now there's some good reasoning. I wont be paralleling cells inside any parallel packs I make in the future

I will also add that making parallel cell packs is a pain in the ass. I much prefer to make a parallel adapter with some deans plugs and spare wire...

Plus you can always use the packs as series or parallel. I did this with 4s packs i had, series in my bombproof emaxx with the 1100kv aveox, and parallel with the 1515 1.5d in the erevo. Just had to make adapters for each...

Yeah I running your packs in different configs only becomes a reality when you have like a billion different RCs though maybe one day I will too :p
