The JL MetalWorx Rechargeable Battery Kit is a collaboration with Thermal Optics Plus to bring customers a lite weight, extremely strong, durable and easy to use solution for running optics all night long without the clutter of pouches and strange attachments running all over the gun. The battery holder is custom CNC'd out of billet aluminum and weighs in at less than 3 ounces, anodized black for a durable coating with lasered logos. Not only will this holder last but it also looks great and matches many higher end optic coatings. The holder features a robust mounting system and hardware that attaches to picatinny railing. Specific cutouts in the metal let you control the battery as well as monitor the power level without ever needing to remove the Anker battery that comes with it; however, the battery pack is as easily removeable as it is secured in case you want to use a backup battery at any time.
(This Battery Kit consist of the JL Metalworx battery holder, Anker battery, charging cable for the Anker battery, and instructions for the Anker battery. It is up to the customer to supply their own cable from the optic to the battery pack; however, virtually every optic to date on the market comes with a cable that will work for this purpose already.)
