12V 7Ah-9Ah 151x65x93mm battery cover for cigarette lighter receptacle

This is a cover to hold a cigarette lighter receptacle, a switch and a display for battery charge status from aliexpress.com

if you have a 12V usb chager and an old UPS battery laying around you can use this to make a handy little powerbank for cheap :D

Edit 2019:

added cutout for new more available battery meter found here
