I own Metz 60 CT-1 and have the Metz 60 CT-1/2 battery pack, I've had problems with the battery holding it's charge. Instead of buying another new battery, I've been thinking about changing battery packs and getting a Quantum Power Pack or something similar. Does anyone have a reccomendations on a good pack to use, that is compatable with the Metz 60 CT-1? I like the idea of a power pack that doesn't have a memory, and is easier to carry around than the large Metz battery pack. Thanks for any suggestions, M.
