I don't know if this is normal, but I have to recharge my probot like every hour if I have him out constantly. My buddy has a probot too and his probot's battery lasts like twice to three times as long as mine. I have a crafting module and medical module (hope I said that right. I can experiment while crafting with him out, and it says he has a medical rate of 65 or something like that). My buddy's probot has nothing. It's purely basic with 40% armor. Mine has 25% armor. Do those modules drain the battery that fast? Or amI doing something wrong? I crafted all the batteries we use and I believe they are all about the same quality.

Any info to help me out would be appreciated.

Thanks!
