The used CP-E4 is an external battery pack for Canon flashes and the predecessor to the Canon CP-E4N Compact Battery Pack.
While we no longer rent this product, we do carry the Canon CP-E4N Compact Battery Pack. You may also find alternatives in the Recommended section on the left-hand side of this page.
It’s powered by eight AA batteries, which reduces recycle time between shots and more than doubles the number of shots you get before you have to swap batteries.
This battery works with:
- Canon Speedlite 580EX II
- Canon Speedlite 600EX-RT
- Canon Speedlite 600EX II-RT
- Canon MR-14EX II Macro Flash
