What battery should I go for?
I will be receiving my Echo1 ER25K tomorrow, so I will be going to the local store to purchase a better battery. What I would like to know is... Considering I will be using this rifle as a sniper, I will eventually upgrade the spring and other internals to increase my fps, though, I am not looking for a faster ROF, but rather strength for the motor to support the springs higher tension. Am I looking for a higher voltage, or amperage? Will a Lipo due to my crane stock be the better choice or a smaller nihm battery?
