Of course we don't want to bore you with some random details of the T500-Rechargeable Energy Storation Unit, so we just tell you this:
If one piece of coal would store 3000 units of power, our RE Battery's power level would be OVER NINE-THOUSAND! Take that, Vegeta! A lil battery can smelt your entire everything to something else!
Ah, and we didn't mention the big feature of our beloved little gadget yet: It's fully rechargeable and completely indestructible. This is meant serious: You can use it as often as you like to, it will never brake of material exhaustion!
However, since RE Batteries are somewhat fragile and therefore could be dangerous to handle if you bunch them up to a cluster, we even designed a special "T500-Rechargeable Energy Storation Unit Storage Device". The lil' Battery Pack is compact, safe, and will store six charged Batteries.
And you can even reopen the entire package by simple RIGHT-CLICKING, that's cool, isn't it? Btw, what does right-clicking even mean?...
Charge it up and you're good to go!
For Battery Pack (Not to be confused with BatPack, which is something else)
