View attachment 212642
mga kailangan
18650 li-Ion battery ( good conditon galing ito sa lumang dell loptop battery piliin ang matinong battery)
cdrking na powerbank 2200mah 1 amp
lumang case na paglagyan sa power bank component. sa akin galing sa pinaglagyan ng bumper case ng iphone4 digibabes.
instructions.
i solder ang mga batter in parallel. then i connect yung circuit board. simple lang diba. ito mga pics.
note: magbasa ng maigi kung paano i solder ang battery bawal mainitan yung mga battery.
goodluck enjoy

so if i want to build a 30000mah power bank.
it will cost me 870 peso.
item list will be
6 pcs brand new 18650 5000mah
1 pcs cdrking 2200mah 1amp power bank
and an old case from digibabe "free"
same construction procedure as before.
my main problem will be the charge time it will take at least 20hrs charging. with my 2anps wall charger. ill be testing this ill keep tgis thread updated
