I hope it is not too much for you...point in your drawing where d parallel connection is.

Each of the cells are 1p. You Series 8 of them, it becomes 1P8S or 8S1P.

Some versions of Li-ion batteries now have a USB C port

Julius1995:
You were there when they offered him that?

Because one Mess is equal to 2 Ronaldo. His left leg alone is worth Ronaldo’s two legs.

They offered Messi 2 times of Ronaldo’s pay, but he rejected the offer. Why? He is the GOAT

billyG:

Good explanation,but I couldn't locate d 1p in d diagram.
What if d 8 cell is to be arranged to get 12.8v?

So from all my explanations, you can’t still figure this out? Lols, Abeg o 😂
I’m still a young man.

LordBiden:
What kind of headline is this?

Did they write yahoo on his forehead?
Where is the evidence of him being a fraudster?

That’s why you shouldn’t be a Yahoo Boy.

HeavenlyBang:


Yes, you can.

Thanks Boss

dollarnaira:


It has no effect at all.
Over yes

Thanks my Oga 🙌

dollarnaira:


It is just that you do sound too practical compared to us with physical experience. Different cells, different chemistry, different applications.

And don't see fire when you make comments. Have you experienced this before? NO!!! You only got the info from the usual YOUTUBE.

At times you make it look that each time one uses lithium ion, next expectation is fire. This is the mindset I desire you remove from your thoughts.

There are several dangers in cars, home, work place etc..

1. Ceiling fan can drop
2. Car accident
3. 220v socket just beside your beside
4. Powebanks are lithium ion based and ppu go about with them.
5. Sitting above car tanks with petrol
6. Gas cylinders in homes
7. Overhead water tanks
8. Phone in your pocket with lithium ion cell
9. Pop can crash
10. Generators with petrol placed in the house/verandah
11. The list plenty bro....

Lols. This is true my Boss. You are a professional and that is why you have eliminated such fear. Unlike Beginner like me, the fear is always their 😂

Good morning Bosses

I have an interesting question. Can I remove the battery of my Lontor rechargeable fan completely and just use the fan like that, via the AC cable? Like, I don’t need the battery bank cos I believe it draws more power. Will the fan still work without the battery connected? Has anyone tried it b4?

Thanks in anticipation

AndroBlaze:


That's fine, I wanted to be sure the latter part above was the argument you were making 👍🏾

I can’t argue with you sef, cos you’ve been here long b4 I even developed interest in Solar.

I'm more of the typical theory guy, who was the best in physics back then in Sec School.

AndroBlaze:


The bolded in theory is not correct. Lion are more energy dense than Lifepo batteries and if the same materials are used to construct them, the Lion will have less weight and give more power.

This is one of the main reasons they were so popular in mobile phones before fast charging led to a lot of them exploding

Yes it’s true, I know that as well. The statement does not oppose Li-ion, but do you see Li-ion in that high capacity range (20Ah, 23Ah, 50Ah etc) like LifePo4? I guess the answer is no. It’s not common to see them, not like they don’t exist.

This is also obvious in this thread, because a lot builders here uses 3.2Ah or a little above capacity. If there were 20Ah Li-ion cells around, nobody will have that luxury of time to weld 644 cells when you can easily do so with just 8cells. Haba. This is why I said that LifePo4 contains high capacity in small body.

Intellab:
I had some challenges with my previous 18650 battery setup. I used 644 cells configured as 92P7S, but it couldn't power my 1HP Sumo pump effectively.

So, I upgraded to 314Ah LiFePO4 batteries — 8 pieces in total, giving me around 8kWh of usable energy. I built the pack using a JK Bluetooth BMS with a 1A active balancer, 4*250w solar s, felicity MPPT.
Batteries and the BMS were sourced from Valto.

I also switched to a 0.5HP Sumo pump, and now I have 24-hour power supply. The Sumo, washing machine and a lot runs smoothly — everything is up and running without issues 24/7.

I prefer LifePo4 battery to Li-ion battery for so many reasons:
-they can contain much larger capacity in a small body.
-Their connection is not hectic compared to you welding 644 cells of Li-ion batteries, especially when you can achieve such with just 8 cells of LifePo4 like you did.
-Fire safety
-lasts longer etc.


But Bro can you show us an image of your output (discharge) and input (charge) connections if it possible.

cutefy:


It's 177k, if you're getting it from Cworth distribution center.

Wow! 100k difference. Just Wow!

fuckboys:
well, my power needs is way above 100ah battery now. I run constant 200w all night.

Yeah that’s the point, everyone has their specific power needs aside the finances.

billyG:

Nice explanations,now if I have 8 ( 3.2v) Lifepo4 cells,I want to build 25.6v what will d combination called and what bms to use?pls use diagram to illustrate d connections.

Sorry, I forgot to leave a reply.

You have to connect each of them in 8 Series to get 25.6V
Because 8 × 3.2V = 25.6V

that series means constant Ampere but increase in voltage. So if you add up all the voltage of the 8 cells in series, it will give you 25.6V.
Total capacity (let’s assume each cell is 20Ah):
25.6V 20Ah
=512Wh

Since each cells (I.e one cell) are all connected in 8 series, you can call it 8S1P or 1p8S. This means you’ll need an 8S (eight series) BMS.

Just understand that BMS helps manage your connection on each series. So if you create a 10series connection, you’ll need a 10s BMS.

This is a diagram below

fuckboys:
an extra 180k would get you 280ah 3.6kwh battery. This is not value for money any at all.

Wahala for who no get extra 180k 😂
Or maybe it’s just his total energy requirement and therefore may not need more than that capacity.

Elizkid:
Does anyone have an experience with this?

How does one know if it’s genuine lifepo4 battery, as I don’t know if Cworth has a warehouse situated here.

The price is 276k.

Ha, this battery that was 206k the last time Damrey posted here is now 276k??

Demand?? Or is it a the normal Nigerian thing to just increase the price for no reason?

Nna2025:

Dear Nairalanders,

My company asked a couple of us to resign, services no longer required. I was paid a little above 10M and I will be venturing into lending. Microlending. Please say your prayers for me and wish me well. I will appreciate all you prayers and encouragement too...

Thank You and Regards,

If this is the only business you can think of Bro, especially with the nature of typical Nigerians? Bro I won’t wish you well on this one.

HeavenlyBang:


Tested on lowest speed. Lasted 11h3m. Voltage when it shut off was 9.7v.

LVD of 9.7v
HVD of 12.3v

Within spec for Li-ion, I believe. Experiment looks like a success. If this gives me 18 months of use, I'm a happy man.

This is cool.
Meaning your fan’s power consumption on low speed is around 8.5W/h.

I would assume that on full speed, your battery can chest it for about 3.6hours. But I can’t be sure since I have no idea your fan’s original power rating.

But on a second thought, you could actually build something like this for yourself—even better than this though.

billyG:

Does this means all d side up is welded +ve & d underside is welded -ve in parallel connection?

Yeah that’s correct. One side is positive and the opposite side is negative. I was like you too 😁

Those 24cells are all connected in parallels already, meaning that the positive terminals of each cells are welded and connected all together, and the negative terminals are connected all together as well. That is called 24P. Then each of them will be connected in series to form 3 series. This is why it is called 24P3S. And for this to work, you will need a 3S BMS (I.e a BMS for 3 Series connection)

To help further (I don’t know if it’s necessary though. But I love maths😁)Now let’s do a quick maths:
Assuming each cell has a rating of 3.7V and 3.2Ah

The 24 pieces that are all in parallel will give:
= 3.2Ah × 24 = 76.8Ah capacity and 3.7V.

Nb: When you connect in parallel, you increase the capacity (I.e the Amps) but the voltage doesn’t change. This means that the 24 cells in parallel has a constant voltage of 3.7V but Ampere of 76.8Ah in total.

Let’s continue. So now that you have 3 units of 24Parallel cells, it means we have 76.8Ah 3.7V in 3 places. He will go on to connect the 3 of them in series. Let’s do the maths.

that connecting in series increases the voltage but keeps the Ampere constant, so let’s add up the 3 voltages:
3.7V + 3.7V + 3.7V = 11.1V
Total capacity will then be:
11.1V & 76.8Ah
=11.1 × 76.8
= 852.48Wh

But ofcourse, the capacity might not be up to that at the end of the day.

I hope this helps.

No boss. I am still learning trading patterns. Planing to learn for the next 2 months b4 starting. I am also raising about $500-$700 for the trading, by God’s grace. I have been here b4, but as a novice. I lost everything. This time, I don’t want no regrets.

Alexas58:


That $2 profit is worth it to me…

Even $1 is worth it to me

Alright Boss. All power belongs to you 🙌

lavylilly:
Thank you for sharing something this personal — your thoughtfulness and sense of responsibility are clear in every word. You're caught in a very human tension: between duty and desire, family and self, stability and growth.

Let me be honest with you, from both a practical and emotional perspective:

💬 The Truth Is: Both Sides Matter Deeply
On one hand, your parents are aging and you are currently their closest system. They likely feel more secure just knowing you’re around — even if you don’t do everything yourself.

On the other hand, you’re a grown man with your own dreams, and it’s completely natural and necessary to want to move on — to build your own life, relationship, and legacy.

This is not selfishness. This is life unfolding. It’s not “either them or you” — the goal is to find a balance.

🧩 Let’s Break It Down:
1. You Deserve to Move Forward
You’ve worked hard, become financially stable, and now want to build your own family. That’s not just a wish — it’s a vital life stage. Suppressing that desire too long can lead to frustration, regret, or even resentment. You’re not just living for your parents — you are also allowed to live for yourself.

2. Your Parents’ Needs Are Real Too
Yes, they are old. Yes, they depend on you. And yes, things may become chaotic if you just disappear. But that doesn’t mean you must put your life permanently on hold. What they need is — not your entire presence 24/7.

💡 Practical Steps Forward
Instead of viewing this as a “stay or leave” decision, build a gradual and ive transition plan:

✅ 1. Talk to Your Parents
Have a gentle but honest conversation. Reassure them of your love and commitment to their well-being — even if you’re not physically living with them.

✅ 2. Stay Close By (If Possible)
Can you move out but remain within the same city or neighborhood? This keeps you close enough to help and check in regularly, while still giving you the space to build your own life.

✅ 3. Hire or Assign Help
If finances allow, hire a trusted caregiver — even if it’s for a few hours daily or weekly. Alternatively, see if a trusted neighbor, church/community member, or even a rotating sibling visit schedule can help reduce the burden.

✅ 4. Use Technology
Set up security cameras, smart home devices, or medication reminders. Regular video calls can help them feel your presence. Technology can bridge part of the gap when you’re not there.

✅ 5. Build a Routine of
Create a routine: grocery runs, weekend check-ins, house maintenance, etc. This provides them with structure and reassurance even if you’re not living under the same roof.

❤️ Final Word: You’re Not Abandoning Them
You are not leaving them out of carelessness — you are growing, and that’s what they raised you for. The best gift you can give them is not just daily presence — it’s becoming fulfilled, strong, and able to care for them in deeper ways.

You can leave the house, but not leave their lives. There’s a way to be a good son and build your own life.

ChatGPT. Try to reason for yourself than rely on AI.

Alexas58:


Does this answer your question?

Even the system is warning you

Bro, I understand this perfectly. What I am trying to say is that, perhaps there is a mistake with your leverage.

Going into a trade with $11 and a leverage of 2.99x means you have $33 (I.e 11*2.99) for the trade. Now according to your trade, even if BNB goes down to $640 from your entry price of $663, you are only making a profit of about $2.

33/640*663-(33)=34.1859-33=$1.859 to be precise.


So this is why I asked you that question. Perhaps you have your reasons, but frankly speaking it ain’t worth it.

Alexas58:
We short bnb

Bro is there any reason for using such a low leverage (2.99x) for a small margin? Or is that a mistake?

Gentlesoul2021:


If all of his elders are wives, it MAY work not WILL work. I personally will never release my child to go and stay with aged parents...

Interesting. So what exactly is your suggestion then?

Gentlesoul2021:


And u think the husband of his elder sisters will want to release their children.

He didn’t specify if the elder siblings are husbands or wives. Whichever one that applies should work. Even if all of them are wives, it will still work.

HeavenlyBang:

Thanks Bro.

Have you tested the run time and discharge on highest speed or something like that?

I am very curious to know what the results are.

I have this lontor table fan (pics attached) that doesn’t last beyond 2hours on full speed after a full charge with all the hype.

HeavenlyBang:
I bought the li-ion battery pack on Jumia as a replacement for the lead acid in my rechargeable fan btw.

Battery came in at 11.6v, which should be about 65% SoC in a 3S 18650 setup. Pins don't match so I just ripped off the pin on the battery and connected directed to the fan's pins. Works fine.

Discharge/charge behavior remains to be seen. And that's what concerns me most. After all, lead acid is effectively at 0% SoC at 11.5v while a 3S li-ion is still at like 50% at that voltage. Hopefully the fan's LVD doesn't Bleep me over. Will update.

Could you kindly show the picture ads from Jumia. Thanks.
