EOTech 511 AAA battery cap conversion by tomfrajman

Last crawled date: 4 years, 1 month ago

EOTech 511 holographic sight is normally running on N type (LR1) battery. These are expensive and hard to find in some places. Therefore I decided to make a custom battery cap that runs AAA batteries. These are cheaper, more common and also last longer (750-800mAh vs 500mAh).
