Flash Battery Pack replaces CANON CP-E4
Mdl#FB-1(II)        Sku#36518

The external JJC Flash Compact Battery Pack FB-1(II) improves flash recycle times significantly and increases the number of firings before batteries need to be replaced. The pack can be loaded with 8 AA-size batteries - alkaline, lithium, or Ni-MH - prior to a shoot to ensure fast and smooth transitions from one battery set to the next - important in critical shooting situations or to keep up momentum in the studio. Total minimum flash recycling time can be as fast as 1seconds when used with AA Ni-MH batteries.



     Compatible  with

Canon 600EX-RT, 580 EX II, 580 EX, 550 EX, MR-14EX, MT-24EX


Gross Weight





One year warranty

JJC: Dear customer, thank you for your purchase of JJC product. Before using the battery pack, you need to store fresh batteries into your Canon 600EX-RT flash. Then you need to store fresh batteries into the pack. By the way, please store the batteries in the right way. Welcome to contact us again if you have any other questions.
Hello, I bought this new to use in combination with Yongnuo YN560-III. When i tried a series of shots, recycling time between shots did not reduce (reains at approx. 3 seconds) and batteries inside the Yongnuo became extremly hot. Seems that the flash was not powered by the Battery Pack. When I plug the Battery Pack into the Yongnuo (without batteries inside the Yongnuo!) nothing is working, and also the Control LED at the Battery Pack remains dark and Yongnuo is not working. When I add batteries also to the Yongnuo, then the red LED turns on also in the Battery Pack. But seems not to work with them. Only Batteries iside the Yongnuo become hot, and no reduced chargin time between photos. When i try to measure the Voltage on the plug that is to be connected to the Yongnuo, there is no Voltage measurable (means no output?). Is something defekt ? Should I return the product to te dealer in Germany ? Regards Wilfried Wilfried Kuch
