Review on Kraken Hydra 3500S+ WSRU: High-performance Underwater Video Light with Flood, Spot Lumens, and Strobe Capabilities by Chadwick Webster

light seems to work with all features as advertised, haven't taken it underwater yet. I deduct two stars for the insanely expensive branded battery. Anyone know where to get replacement batteries? It appears that a standard Li-Ion battery was housed in a branded triangular case. Selling extra batteries for $130 is a crime. It looks about the same size as the 32650 Li-ion batteries in my other dive lights.
