capacity of this powerbank depends on what tipe of the 18650 cells are you useing i used 8x 2000mah batteries so my powerbank have 16000mah.
Guide:
if you are useing recicled battery cells make sure you balance them to the same voltage.
put all the batteries in holders and solder them in paraler (soldering 18650 batteries is hard and dangerous make sure to watch this video:
after you solder all the cells wrap the battery pack in electrical tape like in the photos.
put the battery pack in the powerbank case and push the positive and negative wires of the battery pack thru the hole. solder the positive wire to the B+ termial on the pcb and negative wire to the B- terminal. secure the pcb with 2mm screws and push the thermistor of the pcb thru the small hole in the battery pack. secure the powerbank lid with four 3mm screws and you are done.
