Hello crazy ebikers! This is Randy from TexasNEV again bringing you the best and most unique extreme power ebike products out there.  I have a batch of triangle / trapezoidal double thick massive 40aH 72v (84v) ebike batteries that pair excellently with my hub motor kits I have for sale.  These things are a beast!
The last batch I had made up custom were a 20s7p 35aH pack w/ a 84v 5a charger and 80A BMS.  Customer feedback was great, but the general comment was that they would preferr the extra capacity and current of a 20s8p with a larger BMS, SO, we LISTENED and have these enroute! 
People have asked as to why these are so expensive, well to put it simply the rectangular packs are 20s1p of flat packs.. Stack em, bond, em connect 'em up and shrink wrap 'em.  MUCH less labor.
It takes special design software to make custom geometric shapes and knowing where to put the cell bridges and make it so that it can fit inside a triangle frame.  Connecting up 160 cells in a custom pattern is very time consuming.  Plus, these are grade A Samsung cells..
