😊....you just let out a powerful secret.. I have done my studies well, and DC charging is the most efficient for USB chargers. You could be saving up to 30% energy that would have been wasted if you used an AC source.

I once asked a guy here that said he sells power if we could link up, but na air he air me....I just smiled.

Knowledge no de finish for this life.

good evening one,I came home this evening and my children told me around 1pm or 2pm my inverter was piping and when dey off it,it started smoking though still working and when I open it to see what is wrong inside I found out some capacitor are burnt . though the instill working.what is the function of those capacitor and how can I fix the problem. 3.5kva yohako inverter

It depends on a lot of things I think yours is an aging problem resulting in high esr (there's no explosion of the capacitor but rather a kind of burnt around the label)

Now since you said you put it back on and it still works as if nothing happened, it likely proofs that it's not a really serious problem, just checking if there are any burnt trace, decolorations on the PCB, might give you more hint of there are other problems

sorry bro, though scammers abound, but he is 100% legit and nothing to fear

codemaster2much:
please folks, plan heading to Arena oshodi this weekend to get a used 12v inverter 1kv, to 1,5k etc for a small use case, I initially wanted to go with a sachet inverter but I am thinking a 12v used might be better since there is a good chance of getting a pure sine wave inverter, please who can recommend a used brand to go for and which one to avoid, and please who knows a reliable seller, also like how much make Arena go finish me, those guys can be very vulturous is person no sabi and could even sell a bad one

So what exactly have you learnt if you are gonna ask such a basic question?
Some of us are just quite funny.

Guys, Please what are your take on this:

So i have been following this tread for some time and from poplular recommendations to others , I was convinced and then I ordered and received a 3.2kwh battery from a buider on this forum. The delivery was fast, no delays. Although the set did not come with any accessories, no baterries cable etc . This was as stated by the builder. ....(only the battery box in a plastic build with a small bms screen and a button). All as advertised. So no issues there. This setup cost #550k (delivery inclusive). All i got in addition was the waybill receipt

The truth is, my friend who ordered for a 26.5v(100Ah) itel 2.5kwh battery, received theirs yesterday:
To my supprise, the itel battery Bank alone was 2.5 to 3 times heavier than mine, the setup was built in a solid steel housing case, has 3 internet communication ports, and 3 other advanced looking ports. Came with ALL the comm ports cables, also came with two 20 mm solid +/- battery cables , 3 year warrenty card, thick steel wall brackets, metallic wall screws, some addtional bolts and nuts and many more.
And all this cost #481k (including delivery fee).

Now I know why people crave the itel battery pack.

Although I have to say I over expected much for mine, but the person i bought mine from did not give me the kind of attention(as a first time customer as i would have wanted) the response sometimes was quite slow (had to literally push for any information with response coming anything it comes) no step by step on how to do much. I had to ask about value to set for bulk and float etc, Had to push and ask or most times google some stuff on my own. (I am not saying the seller did anything wrong o) but sincerly I dont think I may patronise the person in the future.I like my business partners to be approacheable irrespective of the value or amount involved in the trade......(my choice)

So, the itel on the other had virtually a full hands on manual that explains EVERYTHING you can do, clearly defined warranty card and many more quality of life stuffs you know.....

Although, I for one became a bit skeptical about the build i received (when i recall the itel heavy weight and quality) but everytime i checked the jk bms app, i showed all the cells adds up to 3.2kwh (see image). Even still, my mind still tells me I should have gone with the Itel due to its solid built, wall handing capability, solid customer and aftersales support, the quality of work and support it has.
(I thought going for "3.2kwh" was better than "2.5kwh" so i had to stop my initial itel order for the local build).

Its well sha


Forgive me for my long epistle...Just wanted to air my thoughts man.

Thanks Guys

SourYoghurt:
I might be wrong but I see this as itel promotion, lol. Well, speaking about googling thing, that's how you build character and knowledge when it comes to learning. In addition, I'd really want to see the battery grade and actual capacity because I know for sure their "30,000mah" is lesser than advertised so I believe the same thing with their shinny battery box too.

Conclusively, to each their own, but I am not interested in aesthetics but rather value, peace and honesty, I don't care if it is "wooden" if it works and delivers when I want it to, then that's all that matters.

CuteMaro:
While your feelings are valid, 550k for 3.2kwh is not a bad deal at all. You get more capacity which you can confirm from the bms app. Can you confirm if the Itel bank holds up actual stated capacity?

Plastic and Steel casing surely won't have the same weight, reason for the significantly heavier weight of the Itel pack. Truth is, buying from local builders might come with some trade-offs, but what is sure is actual capacity per $ is guaranteed which is very important.

It all depends on what you actually want, more back up or features and aesthetics? as long as it isn't a case of what I ordered vs what I got, I don't think you have any issues.

Always remember to do more research before making your final decisions. Don't take anybody's word for it.

Good morning everyone, please I'll love to know if there are any effects if i charge my lithium battery with 120V from the grid. The light in my area can be very low.. As low as 120V.i have a 10kwh lithium battery. Is it safe to allow grid voltage of 120V to charge my battery. If not, what are the potential effects. I'll appreciate any useful response

bassdow:
we don't know the capacity of your charger. the 120v you mention isn't what's gonna charge your battery, at least we hove it isn't.

Even whenyour phone's charger accepts a 240v voltage, it ends up using about 5v to charge your phone.

So if you meant that the NEPA light is about 120v and you intends using your inverter to recharge your batteries (that is, the inverter is connected to NEPA), then i would say so long your inverter is capable of recharging the batteries, and the NEPA light is enough to power the inverter enough, then there shoul;dn't be any issue.

Still, we might need more information to really get you.

Litewriter:
I also face challenge here, grid gets as low as 110v at times, ND I charge my battery with it effectively, so far it's within your inverter input voltage range, most inverters can go as low as 70VAC, the only thing you might experience is, the charging current might not be up to what's set. You don't need to fear anything.

Icent99:
thank you very much, because after a few research i learnt the inverter actually sets the charging parameters to the battery and not the direct grid parameters

Please i need recommended contact to a battery builder in lagos.. i need a 28.8v battery 1kwh at least

I do but currently occupied. Try getting in touch with @dollarNaira or check out this thread https://www.nairaland.com/7902446/diy-lithium-ion-like-minds

Mind you, ensure you giving your project to someone who wouldn't use your work to learn work.

Wonder why not just give @valto or @mrreed a call except you trying to avoid cost of wayBill

bassdow:
That's price range to give idea of price. Doesn't mean you get it at that exact price point.

When I mentioned exact prices, I included names of Valto and mrReed because it's latest prices we got from them between Mid March and 3 days ago.
