Sea Dragon フォト/ビデオライト用 14.8V 50Wh リチウムイオンバッテリー

The battery locks into the light with a reassuring click and holds its charge noticeably well across a full afternoon of video work. At 50Wh, I’ve gotten through two dive sessions without needing to swap, which is exactly what I hoped for.

I was worried about runtime on my shoots, but this 50Wh battery easily powered my light through a two-hour underwater session without dropping below half charge. The 14.8V output feels stable even when I’m running the light at full power.

Popped this in for a full day of shooting and the 50Wh capacity lasted way longer than my old pack ever did. The 14.8V output kept the light steady the whole time, no flicker or dimming toward the end. Genuinely solid backup to have in the kit.
