JTL Lithium Battery for Versalight LED Lights

Designed to provide reliable, long-lasting power for the JTL Versalight LED series of lights. This unit will provide the Versalight LED-35 up to 3 hours of run time, and the LED-36 up to 90 minutes (at full power).

Since it's a lithium ion battery and partial charging and discharging won't reduce its capacity over time, you can refresh it whenever you like.
