For the new Nikon SB900 flash, Quantum recommends the Turbo series battery packs with CKE or CCKE cable .
However the Nikon SB900 flash may cause a Turbo 2x2, Turbo SC, Turbo C or Turbo AC battery to shut down or slow down. (The original Turbo Battery is not affected)
If you notice this condition, Quantum has a software upgrade for the above mentioned Turbo models. This upgrade is free for affected Turbo units under warranty. Out-of-warranty Turbo 2x2, SC, C, or AC batteries can be upgraded for $49.
