topic 600EX-RT with CP-E? in Speedlite Flashes https://community.usa.canon.com/t5/Speedlite-Flashes/600EX-RT-with-CP-E/m-p/58823#M1967 <P>I assume I can use the old Battery Pack CP-E with an 600EX-RT. Is that correct?</P> Sat, 04 Jan 2014 04:04:18 GMT homeboy 2014-01-04T04:04:18Z 600EX-RT with CP-E? https://community.usa.canon.com/t5/Speedlite-Flashes/600EX-RT-with-CP-E/m-p/58823#M1967 <P>I assume I can use the old Battery Pack CP-E with an 600EX-RT.

All the Canon "Compact Battery Packs" put out the same 300 volts. It doesn't mater if they have 6 AA batteries or 8. The output volatge is the same.&nbsp;</P> Sat, 04 Jan 2014 04:58:06 GMT https://community.usa.canon.com/t5/Speedlite-Flashes/600EX-RT-with-CP-E/m-p/58831#M1968 MikeSowsun 2014-01-04T04:58:06Z
