Features: Many flashlights using one 18650 rechargeable lithium-ion battery can use two CR123A lithium batteries at the same time, but because of the difference in the diameter of the two types of batteries, the CR123A battery will shake inside the flashlight. The barrel of the Weltool BB2 storage tube can fit 2 CR123A & can be integrated into this flashlight to solve the problem of shaking. The storage tube is equipped with a lid, which can be stored in the backpack when not in use. The lid has a rope hole, & the storage tube can also be hung on a backpack.CNC machining of aluminum alloy material, black anodized surface. Package included:1 x Battery Holder Adapter
