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.

Dam5reey1:


They have 590w

Bruteality1:



Thanks man. Already Installed this 4.2kva and two 230ah Luminous Tubular Batteries with 550wx4 panels 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.

samnaija:


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:
Delivery to 3 states...
sending...

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

samnaija:

Like i said i don't sell batteries. You either use lead acid or lithium

omotoda:


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

omotoda:


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 .................

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?

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.

Ferdiwar:
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:


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.

ManAdii:

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

Decentlyproud:
Good. Just got one also but yet to install.

ManAdii:

Which model did you buy?

Sapiosexuality:
Hello guys, is there any solar generator that really works for someone who doesn't need a fridge? Any reputable one and link? Thanks.

Just for phone, laptop, light, etc.

dollarnaira:


Seems Linnov sells.
There other ones though.
