Yea, I figured I needed to switch to a large battery, and no the wiring is for the stock.
But there's batteries like :

For the Ak47 type stock, I guess they would do the job, also, Would I need to change the fuse on my wiring?
But would those be enough to power the EG1000 + Sp120 spring setup?
As for lipoly, I don't know if it would run with my current set up.
