That's one way, and it will work. Most of us put pairs of packs into paralell connected pairs, then do the series connections. This works best particularly if you are breaking the packs back into 5s or 6s sections to charge. Half as many series connections to undo then.

Bro, very confusing both photo names are the same but they're different circuits. The one in your OP will deliver 88.8v the last one 44.4v.

Personally, I parallel them at cell level using 2->1 balance plugs.

ok i think i got it this time how is this and what does a three speed switch do?

That looks good to me. Each pair paralelled black to black red to red. Then each paralell pair connected black to red, leaving one black and one red, which go to the controller.
The three speed switch will simply plug into the appropriate plug in the controller. It will allow use of the controllers pre programed throttle settings.

Search out the bulk charging threads. Methods sells some good equipment for it, in for sale new.
I can't or won't try to explain it, since I like the idea that I get to inspect my packs every charge. Wow, that ones hot after the ride! Lets see why. To me it beats, why is the garage on fire?
You can deal with it though, by having each pair of packs plugs on the outside of the case. That would allow charging of each pair at 6s. Use a paralell series harness type setup to make the switch. An internal sensor could give you packs temp, so you can tell when it's going horribly bad in there.

Or get a hyperion 1420i charger. You will require an rc charger for balancing anyway. One power supply + one charger does all (bulk + balance charge), in series (no special harness for series/parallel, disconnecting/reconnecting). And at the price the 1420i is going for (~$130), I feel this is probably the simplest and most cost effective charging solution. As a bonus, the graphing software for monitoring your packs is awesome.
Edit; overlooked the 88v. Ok 2 1420i's

Good choice! The PL8 gets great reviews. Probably the best charger available when you take into account power, features and reliability.
If they made a 12s version I would have probably considered one.
