I'm just reading this and this looks like a threat 😂
But also true

dollarnaira:


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.

Dam5reey1:



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.

Am trying hard. I dont sell batteries like you.
I am full diy, not a marketer like you .I still say it from my personal opinion nothing wrong with lead battery , size it properly. And i will still say ,it sells the most on Nigeria.

Dam5reey1:


They have 590w

Thanks for this update.
I ordered yesterday, they delivered yesterday too.

Bruteality1:



Thanks man. Already Installed this 4.2kva and two 230ah Luminous Tubular Batteries with 550wx4 s and i must confess the experience is so amazing. It's been less than 48 hours it was installed. Will be looking to upgrade in the future to lithium battery.

Enjoy you money my broda. Receive charge to upgrade soon

Properly Size Lead means you will spend more money today than getting a moderately sized LFP. But you result into calling me Marketer like I am not selling Lead acid too, But will I recommend it No..

12V 200AH LFP 385.. 3000+ Cycles

12 220AH TUB 340k.. 1200 Cycles.

Recommending Tubular is like saying come and me at the back... When you know the world has moved on..

You are using 2020 Tubular and wants someone to you in 2025, no be juju be that.

Please engineer in the house my 2 Felicity lithium battery 5kw each is not lasting any more it can't carry load of 500w up to 5hrs any more after full charged I don't know what could be the problem am using 6pices of 350w some time I disconnect the load for two days to allow the battery to charge full still no way I need help on this please my fellow people

Like i said i don't sell batteries. You either use lead acid or lithium. Of course lithium is better, it doesn't mean lead acid is thrash. People are using lead acid and are satisfied. If you want to sell your lithium ho ahead. Like i said lead is still the most sold battery in Nigeria.
My brother sell your lithium battery in peace. But bear in mind people are using lead acid for years and no complain.

Can I get the 12v 100ah cworth lithium battery down to Aba Abia State

Boss,that sizing is the issue. In can guarantee you one or 2 of your batteries will soon die.In fact ,sizing that amount of leaf acid is not advisable.They will go out of balance and die in no time.I agree that people still sell it but in reality now,LFP is cheaper compared to lead and better.I have tasted it small and coming from lead acid,the difference is .................

[quote author=samnaija post=134849201][/quote]

Yes,lead is still the most used but believe me it is out of ignorance and because some installers don't want to move to the brighter side of life

on profile, slowly we will sell to Nigeria

samnaija:

I can now understand your point Fully.

Experience matters sha, I am a DIY, I am an installer, a Reviewer, I build LFP packs, I am a Marketer.

So we cannot see from the same perspective.

You might be right, most installers prefer the easy way..
Now i have said it many times that lithium is higher than lead acid. But what i dont fancy is sales person pitching their sale and painting everything else bad.
The truth Nigerians are cheap people, they don't like to spend money.
Once given a quotation running to millions for lithium, Nigerian instict kicks in and run.

Have you personally sized that amount of lead acid bank. That is what we have in the forum, most of you talking, used lead with either used or new 2 or 4 batteries and killed the hell out of it.

I've been doing some research on it but my I'm still looking for a BSM that can handle 750amps as my car takes up to 700 amps to start.

HeavenlyBang:
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?

Good evening my people. Pls who de sell and price:
1. Qasa standing fan 18" QSF-18R with remote.
2. Qasa dry Iron 300w
Thank you

samnaija:


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.

In as much as i want to agree with u... the price of obtaining 16 tub batt (15.8kwh....50% dod) @ say 250k/290k (average/authentic brands) per battery is not worth it in 2025. u can check out prices for 15 to 17kwh battery packs and ask urself if its worth investing in it.. u also tend to spend more keeping these batteries balanced... what abt the space consumption, Most installers never look @ C rating of most lead acid batteries.. i think that is where thier problem starts from.. its easier to get away on lithium packs with gud bms. All the same lead acid works and still works

Same here.

I've used 75aH batteries rated at 600A crank to start my car, so I'm guessing I need somewhere around that.

My research shows Lifepo4 can handle that instantaneous current discharge, but like you said the bottleneck will be the BMS. You can run it directly without a BMS, but then you risk overcharging considering how alternators work.

Ideally, we'd need a 50-75aH battery, a BMS that can handle 600A without tripping, and potentially fan for cooling so the battery doesn't overheat in the engine bay (or place the battery in the trunk and wire it from there).

I measured my battery voltage with my alternator running this evening and it was at 14.2-14.4v. Lifepo4 can handle that.

The big issue is the BMS.

I've also seen people suggest using supercapacitors to handle the high instantaneous current needed when cranking the engine, then the capacitors get refilled by the battery. That would eliminate the need for a high C BMS, I believe.

Interesting project imo.

Lifepo4 batteries are not recommended for this purpose due to extreme temperatures and fire risk. I hope it's worth it.

Good. Just got one also but yet to install.

ManAdii:

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

Which model did you buy?

Riio sunII 3kva 24v. I think it's version1

Burnerr did you later fix the problem

Chat please advice on where to get original Trina 600+ s.

So I was pretty surprised to see the comments from your trail on the question "can lithium batteries start conventional cars" as I just assumed most people knew this was possible and took it as a given, probably because I am a bit of a youtube freak and the first time I came across normal sized 12v lithium batteries, it was people testing them with cars.

Anyway after seeing your comments and going back to youtube to dig up the videos, I was actually quite surprised that it took a bit of time and there weren't as many videos of people doing so, I mean not like the way I ed it.

However addressing your questions, it seems even if the BMS is rated 100Amps, that won't stop it from delivering far more in the milliseconds it takes for it to start your alternator (see video 1). But to be on the safe side as shown in the middle video post, its probably safer for you to use LIFEPO4 batteries that are designed exactly for the purpose of acting as cranking batteries.

The comments of the other youtubers on the videos is actually the highlight if you ask me, as it shows you people have been doing this for years and the workarounds they've found effective.

Video 1 and 2- normal lifepo deepcycle batteries (video 2 far more informative, but the guy already has a BMS installed in his SUV it seems)

Seems Linnov sells.
There other ones though.

Thank you so much🙏🏼
