I had a brand new 5200mah 3s... but I accidentally over-discharged it....the cell was spoilt even after a lot of recoveries. so I looked up for a replacement cell .... 5200/3 =  1700mah ... I could not find a single retail seller selling a 1700mah cell. so the only options I was left was buy a new battery add up the cells I gave it a thought.... and it would work but I had a dought that I could add up one cell as parallel and the others as series so I made another post. http://www.rcindia.org/batteries-and-chargers/will-it-work/new/#new  .

the second option was to replace the cell by adding up 2 cells which make up 1700mah
so I had 2200mah packs lying around so i thought maybe I can add one of the cells from my 2200mah pack to a 1000mah cell which would make up 1700mah in total.....so I made this diagram .... but i dont know if it'll work ....

Any help is welcomed .... 

Bro you are on a wrong path, if you have 3s 5200mAh battery that's doesn't mean each cell is of 5200mAh /3 =1700mah
, each cell is of 5200mAh which are connected in parallel.
