Thinking of getting one to reduce the recycling time for my 550EX flash, which I find a little slow to recharge, especially when firing short bursts of 5-6 frames, it takes 1-2 seconds to recharge fully. Any idea of its performance when coupled with the 550EX? Or are there any other compatible 3rd party flash battery packs to consider as well which gives better performance than CP-E2? Priority is that it has to have a fast recharge time and fairly lightweight.
Thanks in advance.
