a 2s1p Evo20 800mah into a 4s8p 3200mah

[captain harlock]

Guys,

I'm thinking of buying 8 2s 800mah evo20 lipos and make a 4s8p out of it inorder to have a 3200mah lipo with 16.8V that would make my buggy go crazy.
I cant buy a normal 4s pack because I want a saddle 4s pack for my buggy.

The length of the 800mah 2s1p packs is similar to the length of a 3 celled sub c packs.

The problem is that I dont know how to make a 4s8p out of 8 2s1p 800mah pack. Also, there will be lots of balancing connector( 8 balancing connectors) if I'm gonna build the packs. How can I make an adapter that would join all 8 connectors into two connectors only?

Here're some pics of the buggy:
