Not going to cut it. Broadly the weight of the battery will increase linearly with range. The only way to get a useful range is to make the plane one big flying battery, with no actual passengers.

Actually, you can expect range to more closely approximate logarithmic growth with respect to battery mass. Basic physics.

Depends if you are assuming the same aircraft with the same total eight, and replacing payload with battery, then the battery would scale linearly. If you are assuming a fixed payload capacity and a longer range, then the near logarithmic growth applies.
