New, never used. If you understand dive lights, you know Bobby Franklin's setup is the best for many reasons. My three favorite reasons are the following, which no other manufacturer incorporates:
1. Latchless battery canister is not a snag hazard like many other canister are;
2. Sealed external charging system: battery recharges by simply sitting in its charging base where you never open the battery or any port or plug to do that! No gasket or o-ring is disturbed. Execute your next dive with confidence that you didn't "ding" the o-ring during charging and won't flood your expensive light!
3. Constant voltage: three parallel sets of five-in-series 18650 batteries provide unequaled starting power and lasting power so that light and/or heating systems do not strain under load when voltage suffers nearing end-of-charge. This is a critical part of the design that no other manufacturer addresses, and provides constant power to the end--not an over-driven light that keeps dimming during the dive, overheats, or a heating system that you have to keep cranking to a higher level during the dive. If you do not understand this, read more before you buy your next light, not after!
Specs:
• Made entirely in USA and supported in USA
• 160 watt-hours
• Battery overcharge, discharge, short circuit, and over-current protection
• 600-foot depth rating
• UN/DOT 38.3 rating, TSA-safe, and is certified for safe transport of lithium batteries (including air travel)
Bobby made this 160 watt-hour battery canister as one of his last. He was thereafter unable to source components to build 160 watt-hour batteries, so the current batteries he now builds are a maximum of 124 watt-hours. Why settle for less? Take the most power underwater with the best battery, light, and heating system you can.
I also have an Underwater Light Dude new, never used charger and SECS charging base for additional purchase. Ask me about a brand new Underwater Light Dude 5K video light as well, or a used Underwater Light Dude LD-40 dive light! Video light head is shown as additional purchase.
