Una don finish that guy oo.
By now he will searching for a buyer.

😂😂😂😂😂😂😂😂

How is your tbb doing sir?

All batteries including car batteries will serve you within short period of installation. Which will stand test of time is the question that no longer beg for answers.

Let me push small fear into your spine.Unless you power just tv, charging, and bulbs will this set up do 2 or 3 years or less with careful pampering before you will notice large difference in capacity. Raining season is even coming....how will you full charge it?Sulphation will kill it by then.

If you add freezer, iron, etc be rest assured your system will fail in less than a year.

Assuming you didn't know this thread before now it would have been a different issue of "had I know". But you deliberately shot your upper limb with your eyes opened .

2 tubulars is roughly 550k or more, that is more than the cost of 16 pieces of 50ah LifePO4 at 48v with more than 12yrs life span mixed with rugged usage along with washing machine, freezer, iron, all electronics etc without pampering. Today is April 3, 2025 see you in 2026 for update.

What if he doesn't come back?

Lead acid is a battery chemistry of its own.
As long as he works within it design capacity it should be fine.

Lead acid
Agm
Lithium
Sodium batteries
Etc

New battery technology are still coming and you will still say lithium battery is quack someday...

I just dey wait for the day to come.


Let all man choose According to his need,pocket etc.

As long as lithium tech is booming, there will be challenges in managing the waste that will come with it,but till then we might have better understanding and approach to follow

AndroBlaze:


The Growatt inverter you mentioned will carry all the things you mentioned and more.

The question is what size of battery do you have or intend to get?

i got the GROWATT 5.5KWH LITHIUM-ION BATTERY

Bruteality1:



Lol. I'm a novice on anything solar. I'll get it right next time, let me just double my hustle. I believe I'll get the lithium battery by this time next year God willing. Bless

To be honest I ire your attitude and the way you have taken everyone's contribution on your matter.

I think within the one year period you have given yourself to lithium you will learn a lot. The thing you have going for you is that lithium batteries will probably be cheaper in a year's time and Lead's value will probably keep going up, which means the secondhand value of your batteries will still be ok as scrap (BTW I am measuring in dollars and not our pitiful currency).

Keep it up and try and keep this board updated on your journey. In maybe 2 years time you'll understand why we all advised you the way we did and you'll probably be doing the same with a newbie that comes to you asking a similar question.

Also, have you tried the AC yet? Interested to know if your setup successfully carried it.

Interesting choice.

Did you also get the inverter that is made for it and did Fouani install for you? (they claimed to a friend of mine that condition is the only way they will respect the warranty )

Decentlyproud:
How is your tbb doing sir?

My brother that inverter is performing excellently. I'll strongly recommend it anytime and anywhere.

AC

Bruteality1:
No. Only when the Sun is at it's peak I was told. What's DOD

Don't use ac with those batteries, and dod is depth of discharge and tubular is usually at 50 percent. Don't drain the battery completely.

dollarnaira:


AC

Lol, that was how this all started.

Bruteality1:
Good evening guys. I just purchased this 4.2kva Hybrid inverter,2 tall luminous battery 230ah below. 550x4 watts Iwin energy s. I want to know if it can power my 1hp non inverter AC very well. Thanks

Yet another car battery is dying on me. That's the fourth one in less than five years.
I hate lead-acid, man.

How feasible is lifepo4 for car use?

Cc: Valto

Possible to build a pack with fans for cooling and a BMS with parameters to prevent the alternator from being overworked?

Please is there a way of confirming the actual capacity of a LifePO4 battery asides what is written on the company sticker? Is there a way of knowing the exact KWH that is in the battery?

Bashing of lead acid batteries, on this thread. Na wa.

Like what someone said earlier, it depends on your pocket. But has of Nigerian market is concerned, lead acid is going nowhere. Battery banks of all types all depend on how you build it (size).and the source.

Has far has your battery bank is serving you efficiently i dont see any reason to change from one type to another. This is my 6 th year on lead and no complain.

Your build is very important from the beginning, that is all.

Gurus, Any hands on experience with Tasha 1.5kva hybrid inverter?

It may look like bashing but, LFP performance is what is making any lead appear mediocre, Price gap is so close to even cheaper than Lead acid..

People saying Lead works, I have been using my for 5 years, they dont tell us its only 70AH that is left from a so called 200AH.

I was at a location today.. 2 lead acid battery cant last 5 hour using only fans. Na sweat pursue me from the site.

But is it working? absolutely yes, how its discharges so fast and they've only been using it for 2 year+

12 200AH LFP is now 385k.. why on Earth should you buy Tubular or Lead acid that will die in another 3 years when USD will be 3k sorry 1kN

AndroBlaze:

I didn't even see that part?

Okay sir
Thank you so much.

I used it for 4 installations last year, so far no complaints. I have heard complaints from fellow installers though, but personally no issues yet, all installations are at least 8 months.

No need for long talk.

Na so dem say carburetor better injectors too.

I don't get you. I statted a fact that your battery bank whether lithium or lead or gel will all depend on your build and source.

I also stated has of today lead is the most sold in Nigeria. There is a reason.

I also stated that if you build a bank and it serves you what is the point changing.

This is not a superiority contest. I used gel before , then moved to tublar batteries, since it still in service 6yrs. Will still run it till we move on.

Build your battery big enough and make sure the capacity to recharge the batteries covers the bank completely. You are good to go.

Cheers

That is your opinion.

It's a fact, however, that lead-acid is a far inferior chemistry. No one getting into solar in 2025 should be using lead-acid batteries, for their own good.

Lifepo4 is

- Lighter
- Looks better
- Significantly higher discharge rates (0.2c vs 1c)
- Significantly higher charge rates
- Better monitoring via smart BMS
- Better storage capacity, your lifepo4 battery won't kill itself if you leave it unused for months

And most importantly, it'll handle deeper discharges like a champ and doesn't need to be babied. Drain your lead acid battery to 10v one single time and it's bleeped for life. Do that to a lifepo4 battery and it'll pretty much just charge to full capacity when you charge it back up.

You can see from the discharge test result I posted how the lead acid kept discharging lower capacity with each subsequent test, while the Lifepo4 held strong.

Most importantly, lifepo4 isn't even more expensive anymore. 12v 100ah batteries are sold for 200-250k. To match that with a lead acid battery, you need 200ah, which costs 270-300k now.

No one is asking you to discard your tubular batteries. If they serve you, that's good for you. Just don't try to pretend they're a good buy, especially not in 2025.

Ffs there's a reason why the EV industry is booming and not a single EV uses a lead-acid battery bank.

Sir please, does this device read in Amps or in KWH because the engineer here is telling me that the one he has reads only in amps. Please is it the same device sir?

I keep saying you make assumptions anyhow. Has far has i am concerned i built my bank to give longevity. If you started on a not serious note it is your fault your battery died.. I started using my battery during covid 2020 .

16 in number total. And confidentiality no issues, 24hrs light , power any device in my house..

Design and size is important. Dont anyone fool you. The size and design of battery banks are important for both lithium and lead.
Do not believe all this label placed on the batteries body.

Seems Linnov sells.
There other ones though.

You are trying hard to ask people to use 1 Generation computers or Hard Drives instead of M.2 ssd
Ride on sir.

Your 16 batteries cost for cost today is same as getting lithium batteries.

Assumptions:
Mercury Tall Tubular 220AH 12V X 16 units = 42.2KWH
16x 340,000 = 5,440,000

Deriy Batteries LFP 14.3kwh X 3 units = 42.9KWH
3 x 1,850,000 = 5,550,000...

So why Should you Buy Lead acid
