To vyssi napeti plati pro nabijeni, ale pro udzovani je to strasne moc. 6.7 je akorat pro udrzeni. I kdyz ji nabijes pri 7.2 a nechas pah hodin "ustat", padne na ni to napeti na tech 6.7.

EDIT: OBJEDNAVAT??? dyt to je prakticky nejbeznejsi linearni stabilizator s nastavitelnym napetim. To maj v kazdym kramu se soucastkama.
