This thing is a box for a 2x18650 battery holder from Diymore.
Simple design, with both USB port openings on each side and a special opening for the ON/Off switch.
This box was made to make sure the batteries were held properly in their slots.
The batteries i'm using are originals Panasonic 18650 3400mAh.
They are slightly big for the board slots as they have all the protection a battery can have built-in making the battery a bit long.
At the back, i've made special holes to screw a belt clip with the USB out connector facing toward the top.
The whole box is about 210g with 2x18650 panasonic batteries + the plastic enclosure + electronic board + belt clip.
The electronic board is a portable mobile power supply that supports 3V / 1A and 5V / 2.2A two voltage outputs!
5V voltage output rated current is 2.2A, maximum support 3A current
You can install 1 or 2 batteries on this module as they are connected in parallel.
