Sealion replacement battery set

The reason to own a light with a removable battery is this box: a second holder and three more 21700 cells, so the whole pack swaps in one piece. Full power on an L24 lasts about 70 minutes, which is one dive, and a liveaboard does four a day with a single shared power strip in the salon. With a charged spare in the camera bag the light goes back in the water on the next dive instead of waiting on a socket. One thing to know before flying out: spare lithium batteries travel in the cabin, never in checked luggage, which is an airline rule everywhere, Egypt included. Fits the Sealion L12, L15 and L24 only.
