Battery Deficiet?

[Near]

I've been enjoying this game a lot and I am getting better at the melee combat, but I have almost never had enough battery to shoot my rails like one time. I even use the default sword (and have bought/leveled up higher levels of it) but even that generates almost no battery.

Is there some type of loot I should be looking for to try and get more battery? Or are there some mechanics around battery I might be missing?

Yeah, you run out of ammo pretty quck. Hope they increase it.

I also realized the actual issue for me, on top of the low amount of battery-- when i bound the attack key to left click again (after accidentally binding it to something else) it unbound the shoot key.. I had to reset my controls to default to get it to let me bind melee/shoot as the same key again...

I had thought I need multiple battery per shot when in reality i was just never able to shoot x.x
