About
The Halcyon 20 Ah lithium-ion battery is a long-burn canister for exploration and technical diving. With about 240 Wh of energy it runs a Halcyon Focus 2.0 light for around 10 hours on high and 20 hours on low, enough for the longest cave and wreck dives.
It is built as an explorer-style canister with a stabilised battery pack, Halcyon's dry lid design and an easy on-off toggle switch. The E/O connections on the lid also let you run a drysuit heated vest, a winning combination for cold-water diving. Burn time with a vest depends on the wattage of your heater.
The battery lasts 800 to 1,000 charging cycles, and the matching 1.8 A charger is included.
