Do wetin?
U be man or woman?

Chat me up on my mtn WhatsApp to give U address
I dey come with my inverter let's put that battery of urs to a real Load test. Na person refer me come here because of ur hype of Henry Lithium battery. We go on everything for your house including fridge or freezer (no iron or hot plate dou). Ifyu get Inverter AC, even better, my inverter can take it. Iv taken my time to read Tru the chats, seems ur petting the battery smiley smiley, maybe because of the UPS ur using sha. It's time to show that battery how to become a man! grin grin

I also have the 3000 Watts inverter from linnov which I use in my village. I have bought another sachet inverter to replace the damaged one which I am still using with the battery. I am still observing the holding hours of the battery when fully charged. You never can tell, it may be a factory fault.
First calculate and know your total load plus inverter idle consumption, that way even before you start you have an estimate you'll be expecting. After the load test, you can now confirm the pros and cons of the battery.

Lol....
Country hard now , I dare not waste.

My battery is small and it's serving me well,
I regret I didn't buy 200ah and I got extra free 150k awoof money from nowhere last December which I would have added a gotten a 200ah,
By the grace of God, I will get another 100ah soon as more backup

It's okay. We'll go easy on the battery den.
I want a 200Ah+ Lithium Battery and iv been stuck in a dilemma between Cworth and Deriy and now this Henry cry

Iv sent u a WhatsApp message dou..

Also, honestly, if ur worried about burning ur house den u should run far from using UPS and go get a proper Inverter. I remember in 2020 wen my first Inverter got faulty, it was difficult to get it fixed because of the lockdown den so I decided to temporarily rig up an old UPS instead. Got an old 500va UPS, hooked it up with one of my two 200Ah Mercury DeepCycle Batt den, left the UPS open and also fixed a 12v fan for cooling. Got an external battery charger. It was working well, used it to watch TV den until one day I decided to try the UPS function. I put d UPS on and plugged it to mains, hooked up my TV to it, den switched off the mains thinking the UPS function will kick in immediately, omo, I heard a loud bang and the whole Mosfets caught fire immediately! Na God save me dt day o, I think say my TV don spoil sef. I'am saying this because of u that's been using 100Ah size of battery and below but now e dey hungry u to upgrade to 200Ah grin grin
Re: How To Create A Locally Made Inverter With Ease by tziz(m): 3:25pm On Feb 11
Oh, I just found a pic of the setup in my fon and it was a 650Va UPS sef, not a 500Va. I just set it up, I hadn't installed the cooling fan in this picture... Good old times smiley

Thank you for your soothing words. I think the problem arose from power surge of the battery which caused the damage. Please what is pre-charge resistor and how do I get one?
It's just a large resistor used to pre-charge your inverter capacitors in order to avoid high amps in-rish current. Find pics and links below, you can also get it at electrical stores and markets:

I just found this on AliExpress:
50W 100W 0.5R 1R 2R 4R 6R 8R 10R 20R Aluminum Power Metal Shell Case Wirewound Resistor 0.01 ~ 100K 0.5 1 2 4 6 8 10 20 100 ohm

Make he check that battery well maybe na 24v battery dem sell give am as 12v
To his advantage

Everybody gets different headline for him novel,
I have never encountered such with Ups,
I have never used any other type of ups except blue gate or maxtron ,
I am not saying all ups I have used from 2015 till today hasn't have any fault or damage,
Even some higher inverters too have problems or damages in time,
Since I bought this new battery till date, I have never encountered any problem on this 650va ups

As I dey so now, I dey watch the latest Spartacus series releaed December 2025.

Lol,
Nah, na 12v him get. Na that high amperage rush, his inverter capacitors couldn't withstand it, i've seen it happen to a lot of el-cheapo inverters according to my oga Niyi.
When it comes to renewable energy equipments; you get what you pay for.

Lol to U get what U paid for....
I told him to get a 12v 1200va or 650va ups, he said it's bulky carrying around,
I wired mine from sitting room to my bedroom myself so so I do not need to be carrying it around,
These kind of his inverters , I have mentioned long ago,
Me no like am,
If Ur battery is 50% and U have light and all Ur appliances are on, when NEPA carry light, U battery may still remain 50%
I am not saying my ups is the best cos it's not,
But when there's light, ups goes to NEPA mode and Ur charger can charge the battery in peace,
If he's using that battery and loads on while it's charging, he's just killing the battery and I don't have that kind of patients waiting to use my inverter when I have light

Wow, it's been awhile here. We have come along way. But it's like we left ceejay80s behind, thank God you are now about moving forward.
No gear for the battery test. We now even do tear down.
Alot has happened since I came in contact with your group.
Thank you for the eye opener ceejay80s.

No be like that my brother, una do leave me go far far, una don even reach promise land before me

Na cost of material.
The higher you go the better.
Best deal is the 300ah if it is up to capacity.

Probable breakdown:
200a smart bms = 85k.
300ah cells = 345k
Terminals = 12k
Casing = huh
Total = 442k grin
Chief what if I just need 4 units of the 50Ah cells?
I have other materials to construct.
How much?

Not yet. I have not been able to fully charge the battery because of unstable electricity supply to carry out the test.
