I always charge with a reasonable charge rate. And I don't think I should buy another charger.
I need to cut down on the amount of packs I own. The key to storing them is maintainance. Always keeping them topped off and such. Not always do I get time to maintain all packs. Thats why these power tubes look fairly cool. Very easy to swap cells.

EDIT: Yes, I know I'm missing a dial knob

Had to perform a repair quite common to T2's. But it's totally fixed
