this chart is great and shows average power used which Brian worked out before so I can see that I use a bit more than the average of 330 on chart on 4x cell and can see by chart how much more efficient 5 and 6 cell are and that with a few tweeks to me and ecu I need about 4200mah for 6 cell using there average..so a Turnagy 5000mah 6 cell would be fine and 5800 mah for 5x cell so a Hyperion 6500mah 5cell would also be fine..if my maths is correct..correct me if I am wrong... so have answered some of my questions

..still dont know if I will go 5 or 6 cell though
