I'm in need of some dead battery packs for the Sea&Sea YS-350 Pro strobes. Essentially, I want them for parts to re-build them for my strobes. If you have any that you'd be willing to part with for a fair price, please let me know. I might be interested in the AC charger pack too (but really am only looking for the battery packs at this time).
I had a similar problem with my YS300...checkout this place has all the parts you might need including the charger...all the stuff they sell is of very good quality...no more buying $300 battery packs...
They also can manufacture any packs...with a sample or from their standard stock...they even sell Batteries for Canister...I have bought my VR3 batteries here an others...talk to them if you do not know what part numbers you need although the numbers are usually on the cells of the sea&sea pack.
