Step 3: Connect Battery Charger

1. Clean the battery terminals with cleaning solution like isopropenol alcohol & then apply flux to make soldering easier.

2. Apply sufficient amount of soldering metal on battery leads.

3. Strip ends of wires.

4. Dip wires in flux and tin them.

5. Solder TP 4056 li ion Battery charging board to battery , use double sided tape to stick it on to battery.

Step 4: Connect Buck Boost Converter

1. Carefully Solder Input & Output terminals from Buck Boost converter With appropriate Polarities.

2. Connect a Switch to control the power supply.

we're almost done ...

Step 5: Almost Ready to Go..

1. Additionally you can use panel voltmeter to display Voltage and also connect led at the output.

2. Connect a diode at the output in reverse Polarities to reduce back emf from inductive loads.
I really need some help right now..<br><br>that kind of power board is not available in my country... which of these boards can i use?<br><br>this one?<br>https://www.google.com.ph/search?q=ltc3780+philippines&amp;prmd=ivn&amp;source=lnms&amp;tbm=isch&amp;sa=X&amp;ved=0ahUKEwjtytGn7pPTAhWGJZQKHdxuCLI4FBD8BQgFKAE&amp;biw=360&amp;bih=512#tbm=isch&amp;q=150w+boost+converter&amp;imgrc=BylQMLurUM29fM:<br><br>or this one?<br>https://www.google.com.ph/search?biw=360&amp;bih=290&amp;tbm=isch&amp;sa=1&amp;ei=XFLoWNS9J4Hi0gTy96y4Cw&amp;q=5-30v+boost+converter&amp;oq=5-30v+boost+converter&amp;gs_l=mobile-gws-img.3...190944.202527.0.202889.27.23.4.0.0.0.224.2506.11j9j2.22.0....0...1c.1j4.64.mobile-gws-img..1.14.1561.3..0j35i39k1j0i5i30k1j0i8i30k1j0i24k1j30i10k1.6jfUJrOvVB0#imgrc=v0TDbSC6kJbNBM:<br><br>Thanks..
whether I can use DC to DC Buck converter
<p>Can someone sent my a direct link for the Buck Boost Converter. I can just find some similar.</p>
<p>great idea! I'm going to try this one.</p>
I'm going to try this to power a laser diode. Will it work if I connect to driver first?
<p>Why not? It should work if you connect the right voltage...</p>
great idea, i made mine last night !
<p>N1</p>
<p>GREAT..</p>
Thanks
Great job and so simple!
Thanks!
