nice find don!
i agree with the use of multiple stock (or venom

) chargers. been through this before. 2 stock chargers will get 2 batteries done in 1.5hr (or 1 pack per 45min), instead of 1 pack in 50min. add a third charger (which costs about as much as the cellpro), and you'll have a pack every 30min. stock chargers are much cheaper, and having a few of them safely allows much faster charging when you break it down in to packs per hour.
