Lumedyne BLLG & CL3U Battery & Smart Charger Lithium Large

Very Rare working super capacity battery for Lumedyne Flash Systems.
I bought this for a job and used it maybe 4 or 5 times (almost always use the AC power for my
work with Lumedyne)
In open box condition, the battery hold a charge for well over a year
Very few of these were even made, and are almost impossible to find.
The battery can only be safely charged with the included factory Lumedyne charger
(when new the battery & charger were about $1,000)
