Admins Pls push to front page, this is very useful


Today I will be showing you the easiest way
to construct a genuine long lasting power
pack yourself as well make huge money from
these by making and marketing it to your
friends and family.

MATERIALS NEEDED
◾Laptop Battery you ain't using again


◾ A power bank Casing ( you can order it

from Alibaba it cost $4.29 + free shipping less
than 1k) Order it here

◾ A screw Driver and a pen knife.


◾ A wire cutter


◾ Your Head.



HOW TO GO ABOUT THE CREATION



◾Now use a screwdriver or a penKnife to
remove laptop battery casing carefully. Like
the image below


◾After detaching the battery, you should
have something like this and Pull the cell
assembly out of the pack.


◾They are normally held in by double sided
tape or connected using metal tabs.


◾Then carefully cut the tabs/ wires that are
connected to the charging circuit and between
the cells using a Wire Cutter.After separating
the chairing board I kept it for future tinkering.


◾I found 6 18650 Li Ion batteries
manufactured by Samsung.The capacity was
2200mAh.


◾The two batteries are wired in parallel, and
3 parallel packs are connected in series for
the desired voltage and mAh.


◾ Then separate the individual cells.


◾First twist each parallel group and separate
them by using a cutter.


◾Identify the good cells.


Measure cell voltage. if it's less than 2.5v,
throw it away.

Charge the cell. if it gets hot during charging,
throw it away.

Measure cell voltage off the charger. verify
it's between 4.1 and 4.2v.

Measure cell voltage. if it's fallen less than
4v, throw it away. Otherwise record the
voltage.

Measure cell voltage. if cell voltage has fallen
more than 0.1v.

Any cell that hasn't been thrown away by
doing the above test is considered to be good
one.

You are almost there now insert the battery
inside the slot provided in the case and taking
note of the polarity.

The positive terminal of the battery should be
towards the charging board.Sometimes
polarity is marked inside the case.
Then put it for charging by using the USB
cable provided in the packet.


Attach the key chain with the case.
After charging test the USB output voltage by
using a CHARGER Doctor. The output voltage
is 5.06V which is good for smart
phones,Tablet or any other gadgets. And
finally the power bank is ready to use.

nice one

Abeg OP, how much have you made so far?

beware of explosion

Hmmmmmm

Op ur talkin' trash, 18650 Li Ion battery will give you 4.20v - 4.35v, when fully charged, any figure lower that, or lower than 3.7v means the battery is low and needs to recharged.

Nice concept but how many unused Laptop do I have to find to make a power bank. You can only do this for yourself.

d Op is right bro.thou 18650 lithium ion will give 4.2v fully charged. d voltage is stepped up thru boost converter to give 5volts & also maintained tru d feedback circuit

AWESOME. I never thought about this. . .
