Hi, welcome to product review by Robojax. my name is Ahmad Shamshiri and I am
presenting this tutorial from Canada. in this tutorial we are going to do the
review and see how we can use this 0 3 9 6 2A lipo/Li-Io battery or battery charger
module of rated of 1 ampere I'm going to explain the module all the components
and showing you the schematic diagram 4056 chip the pin VCC is
connected then I'm going to show you how to wire it and also charge the battery
or here or USB and these are I'm going to show you the amount of current that
it can provide and charge the battery with an empty battery current at the
moment to the battery let's get started with this.
the module is sold on eBay Aliexpress and the other stores for the price of 30
cents to $5 depending on where you get it before the shipping cost. Here is the image
the main components for the module is this chip 4065E and then we have
DW01A and also here we have A205A . these are the three semiconductor that
are used in the module. this is the controller 4056 and
this is the DW01A this is the protection module and this is the N
channel MOSFET 8 2 0 5 a here we have USB connector where you can correct
micro USB connector to charge it via us USB charger or you can connect external
5 volts that you have positive and negative in here here we have 4
terminals your load will be connected in here positive and negative so whatever
you're running will be connected here if you want to supply power from the
battery or from the source. and then the battery will be connected here positive
and negative in here. on the image here as you can see here the negative is
coming directly to the output you can see this path here and the positive as
you can see is coming here through this chip and the chip is managing it and
allowing it here this chip is the constant current that have been
programmed for 1 ampere
4056 Battery charger (IC) Unit
this is a datasheet for TP 4 0 5 6, 1 ampere this is 1A maximum
current for lithium batteries it can be programmed up to 1000 mA that
can give you constant current constant voltage, battery short-circuit protection
continuous if there is short-circuit it can continuously handle it it has
automatically recharged feature. the programming for the amount of current is
calculated using this formula so we are not going through that because we are
not customizing or designing it but held us here is a programming sheet for 1000
milliamperes we need this RProg the resistor that is needed for
programming we need one point two kilo ohm so if you want to reduce the current
you can do so by putting for example if you put 2 kilo ohm you get 580
milliampere and in between if you put 5 kilo you get 250 milli ampere this is
the suggested layout and we have two LEDs one is for charge LED one is green
LED which shows the standby or the power that it has. this is a charge LED and
this is the standby LED. the program resistor is this resistor as you can see
s is 122 this last 2 means two zeros, 1200 ohm 1.2 kilo ohm which allows it
to maximum of 1 ampere charge. from positive comes and it passes
through this so this is controlling the current for us.
DW01A Battery Protection Unit (sorry for wrong English spilling)
the next component here is DW01A. this is from the company called Fortune DW 0 1 a
it is for one cell lithium ion or polymer battery protection this is for
battery protection. Here are the main feature of it, ultra low current it
needs about three micro ampere to operate. so you can select power down
function or a zero volt battery change function. it has over current
protection and load detection function during charge mode it have different
variations at the end we might have some values but those are not
of our concern and here are the pins that you can see the amount of current
or the charge switch is controlled using external MOSFETs
these are two MOSFETs in one package the datasheet for for that FS 8205 a dual N
channel enhancement mode power MOSFETs this is again from Fortune from the same
manufacturer inside the inside the chip we have these two MOSFETs this is the
source and drain and then the source of the other one and each MOSFET has gates
so for that we have Source 1, Gae 1 drain one and two and source two
gate 2. hear the drain because a drain is connected during one
and two on two sides and source one source one these two pins are the same
we can short-circuit them and here is source 2, source - these are source - and then
the gates are here so these two gates will be connected to their controller to
the chip as you can see them when you connect your battery the positive is
shared with the mainline so when it comes from here the positive goes to the
load and to the battery this line is connected by the battery is not
connected when there with a negative so the negative goes through this MOSFET in
here so the this controller is controlling these MOSFETs to control the
negative path
Schematic viewed
I found a schematic diagram also share this with you let me explain from the
left side this is the two input terminal that you connect and this is the USB
connector the ground from use we will be connected to the ground here and also
the vbu pen is connected here to the positive so USB is done the rest
of the pins are just accessory. we have one capacitor here and then for the four
zero five six chip the pin VCC is connected to 5 volts ground is connected
here we have to standby and charge pins the LEDs are shown here as well and then
this is the output that goes to the battery and this is the programming
resistor 1 to 2 or 1 point 2 kilo ohm to set the current to
1 kilo ohm. the negative this is the output and the positive as you can see
this is the output. to connect the battery the
battery is connected the positive is shared with a positive but the negative
goes through this 8025 MOSFET with this protection device DW 0 1 a
Wiring Explained
And here the module by soldering wires here
these two will be for the input either I can connect external power here or USB
and these are and you can see also for my battery also i put alligator clip
here for the battery as well. and this is my external powers let me connect the
voltmeter so I can show you the power it is 5 volts 5.1 3 in
connecting it to my load one wire is shorter the other is long so they don't get
short-circuited. now we have here 5 volts and this is a constant voltage and
constant current so this one regulated and her I've connected an ampere meter
between this module and my power so whatever current comes here we will see
that this is passing at the battery that I'm using is lithium-ion MH12210
and it is 3400 mAh or 3.4Ah the voltage
the charging voltage they put at 4.2 and 12.2Wh
is the energy and 3.6-3.7 volts that's the nominal voltage
Demonstration (of charging battery)
the battery is not connected yet I'm going to connect it here and then light
is on and it shows 710 milli ampere currently this is now charging the
battery we are reading 4.8 volts at the input
now I'm touching it it is hot now I'm using my Seek thermal camera and let me
open the app so you see which which spot is the hottest and here it shows 77 °C we
can see it shows the hottest spot is the white spot and it shows 78 °C degrees but
it is not increasing so 79 78 °C now if I connect the two terminal of my module to
the battery you will see that it draws one ampere from load but we don't know
how much current this one is taking itself because the module input is 5
volts and and this has 3.7 or 4 volts so we have to measure the current in here and
here when I connect it you will see that the battery is taking 1 ampere I've
connected the polarity in Reverse let me switch them so the polarity is now
corrected this is the input voltage to the module that's the current this is
the voltage on the battery these wires that I've put here this is measuring the
voltage on the battery and this is the current at the moment to the battery the
battery fills up the voltage increases and this current will be slowly reduced
and have the temperature this is the white area is a hottest spot it shows 71 °C
degrees or 72 degrees Celsius. That is this spot the main charger. now
I'm connecting a USB charger here that can supply up to 2 ampere and this is
now showing the voltage across battery and here so that the battery
voltage currently the current show zero I will be connecting this now to the
charger and have you can see the voltage of the battery increased now at 4 and
this is now the current that is being sent to the battery
Conclusion Remarks
for conclusion that I will say that this module indeed is charging at 1 ampere
and it is holding very well it is heating up as I shown you but it is not
critical I've connected both ways from the USB connector and from the two
inputs perfectly is handling the charge of one 1A as you can see here. so
definitely recommended and it is very handy module

Simple cold is killing this many people. While billions of dollars are spent to CONQUERING the space and reach to mars.
through the module this module is dead now heating up and here i've connected
the voltmeter if i connected to this output terminal to the stand you will
see that you will see that I raised three point nine volts without any load
