Is there any reason not to use lithium ion for dive lights. Ignore the difficulties charging and expense. I have enough of them to make a 11v 10Ahr part that is 8" long in 2" pvc pipe.
Another thread mentioned it may explode when it comes in contact with salt water. It wouldn't be that bad to totally seal the battery so that nothing could ever get in. This might have other negative effects.
