This is a spare battery purchased when I bought the Profoto B10X. I charge it using the strobe, but I rarely used it on location, and it has been stored in my bag. In recent years, I've been using other equipment and storing this battery, and it seems unlikely that I will use it in the future, so I'm considering selling it. Please check the photos. The exterior appears to be in good condition. I am also listing this on other sites, so please understand that it may be sold out depending on the timing. Please consider it if you are interested.
