Introduction: HOW TO MAKE 26000 MAH POWER BANK ?

HELLO MY FELLOW !

I AM WAQAR

HERE I WILL SHOW YOU HOW TO CREATE 26000 MAH POWER BANK FOR YOUR SMARTPHONE ATE HOME FOR VERY CHEAP.

+WHY ?

Because it is the cheapest way to get

+WHEN ?

when you want to charge your phone anywhere & any-time .

Step 1: REQUIREMENTS

Picture of REQUIREMENTS

-12... (18650) CELLS 2200 MAH EACH.(from 2-4 old dead laptop batteries from laptop repair shop) about 4-5$

-A EMPTY ROOM FRESHENER BOTTLE. free

-A CAR CHARGER. about 3$

-SOME WIRES. free

-MALE & FEMALE DC CONNECTORS(CCTV ARE CHEAP AND BEST). less then 1$

Step 2: GET THE CELLS OUT FROM DEAD BATTERIES

Picture of GET THE CELLS OUT FROM DEAD BATTERIES

BUY OR HARVEST 12 GOOD (18650) LAPTOP CELLS FROM OLD DEAD BATTERIES

USE SOME TOOLS TO OPEN THE BATTERY BOX WITHOUT DAMAGING BATTERIES

1 laptop batteries contains 6 cells but all are not good you have find the good ones by voltage check or capacity test of each 18650 cells

(for harvesting watch my videos ON YOUTUBE = WAQAR ALAM )

Step 3: JOIN OR SOLDER 4-4 CELLS IN PARALLEL CONNECTION

Picture of JOIN OR SOLDER 4-4 CELLS IN PARALLEL CONNECTION

AFTER FINDING THE 12 GOOD CELLS

JOIN WITH WIRES OR SOLDER 4 CELLS IN PARALLEL CONNECTION AND MAKE 3 GROUPS (3*1 group of 4 cells in parallel)

Step 4: JOIN 3 GROUPS IN SERIES CONNECTION

Picture of JOIN 3 GROUPS IN SERIES CONNECTION

NOW CONNECT 3 GROUPS (4-4 CELLS EACH) IN SERIES CONNECTION .

(it will show 9-12 volts after connecting)

Step 5: CONNECT NEGATIVE WIRE

CONNECT LONG WIRE TO NEGATIVE END OF BATTERY PACK USE BLUE OR BLACK WIRE

Step 6: TAPE THE FULL PACK TIGHTLY

JUST TAPE THE FULL PACK TIGHTLY BY PUTTING NEGATIVE WIRE INSIDE

Step 7: USE SOME DESIGNER TAPE

TAPE TIGHTLY AND MAKE IT LIKE ROD SHAPE

I AM USING A DESIGNER TAPE IT WILL LOOK GOOD WITH THIS

Step 8: TAKE OUT ROOM FRESHNER BOTTLE

GET YOUR ROOM FRESHENER BOTTLE AND CUT OPEN ITS UPPER PART

PLEASE SMOOTH THE EDGES AFTER CUTTING FOR SAFETY.

Step 9: PUT THE BATTERY INSIDE BOTTLE

Picture of PUT THE BATTERY INSIDE BOTTLE

JUST PUT THE BATTERY PACK INSIDE BOTTLE FACING POSITIVE POINT UPWARD

AND ATTACH RED WIRE TO THE POSITIVE TERMINAL OF BATTERY PACK.

Step 10: CONNECT DC CONNECTORS

Picture of CONNECT DC CONNECTORS

JUST CONNECT DC MALE CONNECTOR TO THE BATTERY PACK

AND FEMALE CONNECTOR TO THE CAR CHARGER


IMPORTANT:

please make sure to connect positive to positive and negative to negative

use multimeter to double check the connection

Step 11: FINALLY CONNECT

Picture of FINALLY CONNECT

JUST CONNECT USB CABLE TO CAR CHARGER

AND CONNECT THE CAR CHARGER TO THE BATTERY PACK.

ENJOY CHARGING.

IF YOU HAVE ANY QUESTIONS

JUST COMMENT

Step 12: HOW TO CHARGE POWER BANK ?

Picture of HOW TO CHARGE POWER BANK ?

THE MOST IMPORTANT QUESTION IS THIS

i just use imax b6 ac charger to charge this power bank

BUT I FOUND THE CHEAPEST WAY TO CHARGE

YOU JUST NEED A 12 VOLT POWER ADAPTOR OF OLD WIFI ROUTER OR ANY OTHER

+ HOW TO CHARGE WITH ADAPTOR ?

just unplug car charger from power bank and connect the adaptor to battery pack you are done

but don't charge for more than 3 hours

and just keep checking voltage while charging until it reaches 12 volt .

...................................thank you...................................

warning:

lithium batteries are explosive

please do it on your own risk and responsibility ..

can we use 26650 batteries without using 18650

Ted_lens (author)2016-08-08

Putting recycled 18650 cells in series and charging them without current balancing circuit WILL result in fire and/or explosion.

Yes, you are right but I am using it for very long time.
But you are right it is dangerous that is why I have created another project..

Where are the vent holes in case the batteries discharge on you?

if you drill a few small holes in the bottom it would direct the discharge so you dont have a bomb....

My friend
I have placed inside some shock absorbing materials.
For circuit protection.

with how many Ampere does it charge? and what can i do to change that? android phones need 2-2.4 iphones 1.5, and e-cigarettes 0.5

You just need to get the appropriate car charger
In this tutorial I am using belkin car charger which gives 5 volt 1 amp and 5 volt 2amp.(1amp for normal SMARTPHONES and 2 amp for fast charging devices like Apple)

Yes .thanks for asking how to charge the power bank ?
Answer= you need to charge power bank with 12 volt &1 or 2or 3 amps

The most easy 12 volt charger are power supply for wifi router etc.. They also comes with DC connector . (no need to do anything just connect to the power bank directly )
