pack is ready.

95% ready.

Remains completing the dc step down to laptop.

Although I have tested it. And it works fine.

This is a plastic pack. Won't it melt when the batteries become hot?

I have stronger plastic.

But I'm still using this because I wrapped battery pack with insulator tape at top and bottom.

Strong plastic are preferable though.

Good one boss. You must have studied Electrical and Electronics engineering. Planning to learn from you soon.

my brother, projects are moving. I noticed some parts of my soldering were loose.

And I have redo them.

Pack is working well.

I just repaired a small rechargeable light by changing the battery to laptop battery.

It's a friend own.

So I'm still on .

Never learned electrical in school. But i have innate desire to learn it.

I love solar. And been following by the side since 10 years. Finally got to practice since 2019.

Greetings. Pls I intend changing my rechargeable fan battery to a lithium battery. Normally the fan battery is 6v 4.5ah and from our popular lithium battery which is 3.7v x2 wld give us 7.4v Which is higher than the 6v for the fan. A fellow advised I go for lifepo4 since its 3.2, but it's hard to get. Pls can you help me out on all I need to achieve this. Or if I it like that will it spoil the fan ?

this is very tricky one.

Many roads lead to the market

Please don't ask me the best road.
I will tell you why in a moment.

6v x 4.5a = 27 watts approx 28watts.

Follow any road that will give you 28watts.

Example.
Lithium battery is 3.7v nominal voltage.
3.7+3.7= 7.4 v
7.4 v in parallel will be 7.4v 4a
Multiply them will give around 30watts.

The problem is that fan is 6v.
My issue with this is the charging.
If there's a way to charge the 7.4v
I will consider it. So it's cancelled for now.


Example 2

Build a 12v lithium battery.
Which will be 3.7+3.7+3.7v = 11.1v.
Make it 2p
That would be 11.1v 4a
11.1×4=44.4watts.

Get a step down converter that has voltage and current button. Two blue button.
Step down from 11.1v to 6v.

That's better now because you will charge the battery with normal 12v charger.

The final option is

Add four 3.7v in parallel.
Final output will be
3.7v 8a

Which gives 3.7×8 = 29watts
But we charge this with phone charger.

Sweet

What do you think

thanks for ur swift response. am planning on upscaling the 4a higher for longer usage which is the main aim of switching to lithium. Talking on 12v charger, won't the normal fan charging system be able to charge the battery?

Use option 3. I mentioned here

This allows you join 4-5 battery in parallel.

So you have 4v 8a.
Connect it if fan work, then
Put it back in same place as last battery.

Charge as usual. Thanks

Wow !! God's name be praised.

It's not easy. I'm not a technician but I did it all by myself.

Solar works and proper solar installation works effectively.

Thank you so much for this, I learnt a lot. I am working on a small project, I will really appreciate your input. I just sent you a pm. Thanks

Eliok, you have been doing a good Job. Keep it up, I'm following pl

I want to setup a mini solar system to power my Laptop, 2 lights, 2 Phones and DC fan. I want to do it myself. Can someone guide me?
