Charged... liquid..? Wat.

irondragons

He's Dutch

blinnemans?

Erm, I don't see how that really has anything to do with having been made into a beverage or being charged, so nope.

A lazy tracker.

Basbaas.

If yes, could you explain how in hell all hints except LT and Dutch connect with the nick

It's not basbaas.

The guy is more famous in TM1 than in TM2
He also partook in your interview project.

If he's not guessed soon, I'll just give his name.

ganjarider?! or joost.

Or Braadje. And once again, please tell us how the hell those first hints point to anyone in this whole website.

Space says:
joost

Joost --> Juiced
1. The natural fluid, fluid content, or liquid part that can be extracted from a plant or one of its parts, especially of a fruit: orange juice.
2. Any extracted liquid.
3. To extract juice from.

Also, if a battery is "juiced up", it is colloquially charged, or full of power.
