I used to bring rechargeable batteries and find this is troublesome and the likelihood that the battery goes out on me at the crucial time. Recently was at my coy's family day and have seen the photographer with a external battery pack connected to the flash with a sling bag.
Appreciate if members can help on this:
1. Where can I get one of those?
2. How much does it cost?
3. How many shots can 1 of this last?
4. Whats the time needed to recharge one of this thing?
Appreciate all the advice I can get, cheers!!
