Good morning house, pls I want to know a great brand of DC fan that can cool very well almost like a 26 inches ox industrial fan while saving power

Qasa. May not cool as much as Ox due to RPM difference. But it's an ok power saver brand.

cyif2003:
Nairaland is deleting my post. Pls what cud be d problem

They consider it a spam.

Good morning house, pls how do I connect and activate this smart BMS?
I have gotten this JBD 50A Smart BMS but it's not connecting whenever I try to connect, it does not give output and the bluetooth connection will later go out and disconnect

Balance Leads (Voltage Sensing): Connect the thick black wire (B-) to the pack's most negative terminal. Attach thin white wires sequentially to each cell's positive terminal (B1 to first cell +, B2 to second, up to your S count, e.g., B16 for 16S; unused leads stay uncut). Red wire (if present) or final Bx to pack positive. Verify voltages rise ~3.3V per wire with multimeter before plugging into BMS port.

I can see the discharge MOSFET is off. Turn it back on. I hope the balance leads (voltage sensing wires) are correctly connected.

My people abeg who has handy information of the power consumption of a typical 1hp air conditioner (non inverter models)

Conversion of 1hp to wattage is around 749watt but some 1hp air conditioner n even 1hp pumping machine consume as high as 1kw+, the thing no con clear again

1200w at peak power consumption.

Emm22:
I'm i going to get the exact money when dollar was around 1470 or the refund will be when the dollar is is 1350 now?

I think you'd get the current rate. Forgotten how this works in Naira. My refund was in $. So I got exactly how much I spent on the refunded item.

Emm22:
Pls how long did it take for your refund to be credited to your bank, mine is 3 days now it have not been credited. AliExpress said i should contact my bank for then to process my refund which i did, while Access bank is telling me to contact AliExpress. I'm confused

It takes 4 business days. No cause for alarm. You'd get it.

Lordpubg:
manage it like that bro

Nah, I need the full experience of my phone.

Another dispute/refund brouhaha.
...
I ordered for a smartphone display. It arrived quite fast, but the display turned out to be defective. If you connect it to the board, it comes on. But once you try to put the display in it's position, it won't come on again until you bring it back out. Funny enough, it the screen is on while you are putting it, it won't go off. But once it turns off, it will not turn on until you separate the screen from the frame. This basically means that the flex cable has issues that only appears when the cable is flexed enough.
I immediately opened a dispute and made a video of the issue as much as possible and uploaded as evidence. I also sent the video to the seller.
Oga seller tried to buy time and said I should take it to a technician. Ah! I told him I am a technician.
AliExpress offered a refund of 20% of the price. I refused.
Seller then contacted me and said I should make a video showing the screen in details and then I should destroy the screen in the video. This is to make sure I'm not trying to get full refund when the screen is still usable. If he sees the video, he will approve full refund for me.
I agreed and destroyed the screen in the video since it is basically useless.
After seeing the video, oga then said, "now close the dispute so I can approve your full refund".
Ah! Close dispute? I then asked him how I will get the full refund if I close the dispute. Dude stopped responding.
In case you don't know, dispute is the ONLY way you can get your money back from AliExpress. Any other promises from any seller na scam.
As oga refused to respond naah, I took a screenshot of where he said I should destroy the screen and added it to my dispute as evidence. I also uploaded the video of me destroying the video to the dispute.
2 days later, AliExpress gave me full refund without return.
...
The biggest mistake you can make on AliExpress is to listen to a seller and close your dispute. If you do that, your money is gone. Any promises he is making should be offered in the dispute or implementated fully before you close the dispute.
Don't fall for Chinese people mischief.

Mine was a different story. The display had a line in it, so I opened a dispute and was refunded immediately. I then ordered an OEM display, which cost three times as much as the first OLED screen I bought. Now I’m stuck with an OLED screen with line and every other thing works, and a brand-new OEM one that I’m currently using.

Can speedaf ship electric bike?

I use third party shipper like Noniking for that

Valto:
oya get this, but better soup na money kill am. if u will be into DIY stuff for years to come u need to have correct tools

this is a 0v-60v 50A fully programmable adjustable charger , there is also a 0V-120V 25A version .

I've used this for 5 years now. Very great tool.

bkuranga:
Thank you.
The LG is 1.5HP though, still better right?

Oh, go for the 1HP. Thought bought was same capacity. My bad.

bkuranga:
Between this LG 1.5HP GenCool and Haier Thermocool 1HP GenPal.


Which one will you guys recommend for a solar user?

Do we have anyone with an experience of either? Want to know how power efficient are they?
And the cooling!

LG

adimx:
How many kw of this soft starter will be able to handle 1hp pumping machine on 3kw 12v inverter setup with 3.6kwh LFP battery?

2kw

jikaseo:
Abeg which brand of battery is at that price? I’m looking to get one.

Haisic etc

Tdoctor:
Abeg who knows where I can get a soft-starter for a submersible pump. The initial power draws for pumps is almost 3X the power rating. Please, I'm not looking foe the expensive Schneider et al. soft starters with all the machinery. Just anything that will dampen that initial power draw.

Here you go:

abuzz33:
1.5hp is 1,200W not 2,000W. Surge is 2-3x or 2.4-3.6KW. So your inverter must be able to handle at least 4KW just for the pump to start. Your solar production at peak sun must be at least 1.5KWh or your battery must have at least 4KWh available if you are running it for 3 hours.

Unless you have a very deep borehole or a very high tank stand, like recommended best to go for a 1HP submersible pump if you want to run it with the 3.5kw inverter you mentioned. A 1 hp pump at most needs 2.2KW starting power and 745W running power.

Our 1HP submersible pump consumes 1450w...in theory it's not supposed to be this high....but in reality it does.

Greenodds:
Thanks for the explanation.
Since my post I have done small research. I don't think a 24v system will be able to carry a 1hp AC. A big TV and small appliances like a few white bulbs and 2 small 50W standing fans. My budget is 1M. Don't know if it'll be enough to include quality panels like jinko, and batteries like felicity etc

1) 10kwh 48v battery = ₦1.4m
2) 6kva hybrid inverter ₦600k
3) 8 nos 600w Solar Panels @ ₦115k/each = ₦920k

That's almost ₦3m.

You'd need to up your budget.

waleayeni1:
This is the spec of the inverter. I need recommendations for a good value charge control

Get any 48 volt solar charge controller there is nothing special here the amperage (60A, 80A,100A, etc) what you buy depends on the number of solar panels you are using

Brands to buy in order ofmy preference

1) SRNE
2 Outback
3) Fangpusun
4) Felicity
5) MUST

waleayeni1:
I have 2 Schneider inverters: Conext SW4024 & Conext Sw 4048. I thought it would be a simple connection with solar panels, charge controller and lithium batteries. However, chat GBT tells me that my idea of solar is very wrong. That the inverter can only charge the batteries through grid or generator power. That I cannot charge the battery through the inverter with solar power. I say make I come meet our solar ancestors to help set the matter straight. Abeg make una explain am to me

I have Schneider 4048 inverter...all you need is an external charge controller and you are good to go. Get a good AVR too as it doesn't tolerate poor voltage from NEPA

Tdoctor:
I no dey buy o. Na verify I dey so. Someone thinks he got a good deal but I wanted to verify. If you were to rate Flames Electric, what would you give it out of 10 points?
Second, what do you think of someone selling a Flames Panel at 60k for used 360W?

In 2012 Flames was da bomb, but in 2026 I rate it 4/10

I wouldn't buy 350w used panel for 60k even if it's a tier1 panel.

Tdoctor:
Please, I have two questions
1. Is the Icell X2 Series Inverter 10 KVA inverter a good buy at 600k used?
2. Has anyone use a Flames Electric 360W solar panel?

Thanks

In my days of freestyle I use to favour Flames solar panels...but gone are those days...it's tier 1 or nothing. Also I'd rather buy a 6kw 48V Growatt inverter than that Icell inverter.

Valto:
lolz , so these few details make it to be 700k more costly ?
LVTOPSUN 16KWH used, gangfeng 314ah cells that pulls 323ah on capacity test

VALTECH ENERGY uses brand new Gotion 314ah cells that pulls over 333ah on capacity test with 12,000 cycles. we uses the latest version V19 JK 200A 2A active balancer smart inverter bms with communication ports, our batteries has superior Bluetooth monitoring app. original CHINT 125A 2pole DC circuit.
A well coupled battery doesn't need any fire extinguisher also let me educate u, lifepo4 cells rarely catch fire, rather it smokes and your fire extinguisher ,can't stop or prevent it from doing so.
as for installing it outside ,goodluck with that in Nigeria , u will wake up without light and your batteries

Bro easy on the 12,000 cycles as that claim is sort of gimmicky

I8id:
Honestly, there isn’t much difference. When the earbuds were new, a full charge could last a whole day or even longer, depending on how much I used them. It’s the same with the replacement batteries — their performance still depends on usage, and they’ve been quite efficient so far.

Ok, that is great. Thanks for the update

Geofavor:
Wow. How much is this now?

₦40k

I8id:
The first time I replaced mine was around mid-2023, and it cost ₦1,000 per earbud. The second time was in August this year, and it cost ₦1,500 per earbud, so it’s really not expensive.
I haven’t replaced the battery of the charging case yet, only the earbuds and they’re still working fine. So if your earbuds are weak or not holding charge, battery replacement is a cheaper option than buying a new one.

That is a great tip! ₦3,000 is an absolute steal compared to the price of a brand-new pair of quality earbuds these days. Most people don't even realize the batteries in the buds can be swapped out-they usually just toss them and buy new ones, which is a waste of money and creates unnecessary e-waste.


A quick question for you: how long does the "new" battery usually last compared to the original?

I8id:
do you stay around lagos?If you stay in Lagos or close to major market hubs where electronics are sold and repaired, you’ll definitely see repair shops that fix earbuds and AirPods. I’ve changed mine twice within three years. I use an Oraimo FreePods 3 (2Baba Edition), and the batteries are usually the same.
When you get to the market, just ask around for where they repair earbuds. I usually replace mine at Alaba International Market, Ojo, Lagos — after Ogbosi Plaza, along the road, third staircase, before Unity Bank.
I’m saying this because I’ve seen many people throw away their earbuds once they start having battery issues, without knowing that the batteries can actually be replaced.

My earbuds sounds so good. I'd hate to replace it simply because of battery issues.

Good to see that there are actually people who work on it, as it should. What does it cost to do this kind of replacement?

Geofavor:
How long does your battery last now?

More than 5 hours without ANC and like 4 hours with ANC. QCY Melobuds or HT05

Geofavor:
The QCy earbud I bought just over a year ago no longer lasts for more than a few seconds before shutting down. The battery is gone.

Are earbud batteries replaceable? or that one is gone and I have to buy new earbuds all together?

Sorry about that, fortunately mine still rocks after a year. If you can do a teardown you can search Aliexpress for the battery.

Valto:
Brand new 20ah 3.2v lifepo4 lithium battery with high rate 5C instantaneous discharge now available

How much?This would be great for EV battery application especially ebikes.

richy02:
Guys please I reside around ijaiye and I want someone experienced to help out with a solar system installation, I need something that would carry my tv, two standing fans and maybe 6 bulbs, our power supply has been really poor lately, I would also love to know the estimated cost of the system

Tv+2 standing fans+ 6 bulbs = approx 200w

A 1.5kva hybrid inverter approx ₦220k
1.2kwh lithium battery = approx ₦230k
2nos 550w battery = approx ₦190k
Accessories (wires, breakers, roof mount( = ₦80k

Installation approximately ₦60k

Total about ₦780k

This could go up or down.

This is just a rough estimate.
