New F60 flash issue

Try some other batteries. Eneloops are not very good at delivering amps and tend to overheat. Eneloops are good because they have a long shelf life but NiMH's are better at delivering power. I've done a fair amount of battery testing as I'm also an R/C nut and good batteries are a must and this is what I've found. YMMV
