PROFOTO BATTERIE B1 X

It held a full charge through a long portrait shoot, which saved me from hunting for an outlet mid-session. The recycle time between flashes felt noticeably quicker than my older pack.

Rented this for a studio session last weekend and the battery held up for over 500 flashes on a single charge, which saved me from constantly swapping packs. The locking mechanism on the mount feels solid and secure, no wobble at all.

Had a shoot on location with no wall outlets nearby, and this rental battery kept the flashes firing all afternoon without a hiccup. It was ready to go the moment I picked it up, and the charge indicator made it easy to plan my next setups. Exactly what I needed for a full day of shooting.
