Gasopanis:
I have been having some kind of pain in my ear for about 2 weeks now, i went to the hospital last week and i was prescribed this drug Augmentin, i was shocked when i went to the pharmacy and was told it costs 57k, i even had to ask the lady if she knew what she was saying, i had to google it and found out she wasn’t lying. I went to buy it today.. it has just 14 tablets. A friend of mine told me it used to cost about 6k in the past.

I’m fed up of the situation of things in this country
I bought this drug for 7k in February.

Please how do I make use of the buck converter?

Can use my laptop charger to charge it using the buck converter to step down voltage?

Good job,but the discharge and charging wires are too small
the capacity is just 40ah, by the way the wires for the discharge and recharge are pure coppers.

I can't seem to solder wires on my batteries
Any suggestions
I once experience that scenario, I went on youtube to see tutorials.
Although I bought a new soldering iron from aliexpress that heats up in 5 seconds and the rest was history.

Hello, bro. Keenly following this thread. Is it advisable to use UPS to power li-ion batteries? I read in a blog that most Nigerian UPS are built for lead-acid batteries. Please, throw more light on this, so I can continue from where I left off
the UPS is no powering the li-ion batteries, the batteries is the one powering the UPS.
Any battery can serve as far it's the rated voltage for the UPS.

All electronics
Except Ac and iron.

Note at 11.0 or slightly below it won't power freezer due to surge. Every others work even at 10v
omo! 🙂 lithium sweet be that.
Though my house setup is still performing wonders since after two years.
But I just want to build this 12v 40ah system for outdoor use.
DIY power station, I'll be making use of the ups I bought from valto since 2020 for the setup, I'll meet a furniture to build me the case.

My amp hmmm?
348 pieces
Amp is roughly 230A or more bc i got tired of capacity testing..
wow!
How's the performance, and how did you source for the cells?

Bms will balance only what is right.
how many amps is your build?
Technology Market › Re: Diy Lithium Ion Like-minds by officialfestus(m): 10:57am On Nov 24, 2023
dollarnaira:
Not bad but you need to know the voltage of each cell. Since you didn't have the right devices to work this process effectively, disconnect all negative terminals and observe again for self discharged cells after some days. IT IS VERY IMPORTANT.

Without needed patience your build will turn bad.

I waited for more than 3 weeks in my case just to be sure of things.
Who dey build lithium ion pack no dey hurry o.
Thanks.
But before soldering, I tested all cells and removed the ones that self discharged within that 2 weeks frame of waiting for my package from aliexpress.
Technology Market › Re: Diy Lithium Ion Like-minds by officialfestus(m): 10:22am On Nov 24, 2023
@dollarnaira
I thought it was the function of a bms to balance the cells by itself.

Buying a liitokla 18650 battery charger is too expensive.
Technology Market › Re: Diy Lithium Ion Like-minds by officialfestus(m): 10:12am On Nov 24, 2023

@fesstus
Good job!
But have you balance charge all cells before running as 3s? It is VERY IMPORTANT.
I charged them, but not fully charged, I have solder all of them together, but only in parallel connection.
While in parallel connection, they'll balance themselves.
This morning when I tested the voltage, they were.
3.8
3.7
3.69

Your laptop is gone. That's same with my own. That's what happened to mine.

The board has been affected and can't be repaired.


Beware of laptop mechanics or engineers, they will change your screen, and keyboard after confirming what I just said.


Be warned. Buy a new one and avoid stressing yourself.

Once I hear HP laptop, I run oooo
my case is different, I tried resetting the pc, while resetting, it took too long to reset, so I had to interrupt it, that was how the problem started.
