How do I increase the energy limit for my bots?

I want to add some cool weapons on my arms, but I keep running out of energy. Is there a way to increase the upper limit somehow?

Somehow managed to find out.

Every time you level up, you get to choose upgrades in a list of upgrade "cards".

One of them happens to increase the upper energy limit.

To increase the limit you have to increase the FLY stat and these upgrade cartridges are helpful i recommend getting the Capacity cartridge for the first 3 lvls since they higher the cost so you will be able to get more parts on you =P.

Also there is a wiki to know what each upgrade cartridge do...

Ill get it and post it soon.

[EDIT] its already in the guides section so just go there and click on Catridges i think, wait ill go check it again.

Also dont double post just edit if you want to say something more
