truthbetold22:


This man, your defense of lead acid batteries over lithium is so pathetic and lame that it beggars belief. You do not want to move on from your old and obsolete technology, congratulations..

But please, stop trying to prove that lead acid is problem free because again, you have invested in a 48v 2000ah bank and a 40kw solar array so you can afford to discharge to 80% only.

Isn’t it pathetic that you know more than the white man who invented both battery chemistries. Isn’t it also lame that you know more than the white man who choose to use lithium batteries in laptops and electric cars with many of this electronics going 10-15 years on the same battery

Finally, who told u that lithium users battle with voltage and balancing? You are so stuck with old technology that you won’t do your research on how lithium works. Lithium batteries are coming with 5 year warranties and you are speaking English. Even for diy coupled cells, a proper bms and a reltec balancer and you are good for 5 years.

Please stop misleading people with your oversized bank and your oversized panel array. Not everyone can afford 10 million Naira arrays.

Allow people with small budgets to get lithium batteries that can stand the test of time and can get filled up quickly without 40kw arrays.

Enough of all the lead acid hype. All lithium users have had lead acid disappointments before we all ran to lithium.

You don hear person come here say e lithium battery don fail since 3 years wey people on this thread start to use am?

Wetin u wan hear again?

...in other news, i had to perform due diligence on this new baby over the past weekend.
thanks to my brother sege in benin for making this possible. this third installment in magnum
is now live and firing beautifully (still under observation).

GeorgeD1:


again, my brother i think it bears repeating here that no one is saying lead acid is better than lithium.
op saw some 2v batteries and asked an innocent question (which really only needed a simple answer).
but, what did he get in return? instead of a simple answer, peeps jumped out calling 2v single
cells 'obsolete' and making all manner of suggestions as to how lithium has now overtaken lead acid.
a renewables newbie reading all that might be misled, so i was only trying to put the records straight.
nothing more than that.

samnaija:


You take what you want and leave the rest he wrote. Majority of people singing lithium in here have an agenda period.
To end-users other options are available apart lithium do your research well.

ojeysky:


Na wa o....Kai this one shock me o. It is well sha.

samnaija:


What is shocking, a man asked about 2v 500ah batteries, the next thing it is useless infact you can't carry it , another said you have will find it difficult to charge it
Please go and read what people wrote and he asked a simple question on 2v 500ah.
Please if you are marketer you are marketer.

If you by chance have used the 2v 500 ah battery before please contribute to the knowledge of all. Like I said earlier I have used it. But majority of people castigating have not. George is presently using it someone said he should keep quiet. Why?.
Pls let people speak in peace when geniune end users ask for advice on a product.

ojeysky:


It's not about using 2v 500ah before. It's whether those commenting have used lead acid before, be it 2v 2000ah or 12v 100ah, it is still lead acid hence operating principle is absolutely the same.

What is shocking is that you don't seem to realize that people are speaking from experience of using both lead acid and lithium, you feel people are just trying to market lithium and intentionally have readers misinformed for personal gains.

samnaija:


No ,someone asked about 2v 500 ah batteries simple. The lithium sales men started their pitch immediately.

It's like me I have not used lithium, so I cant pitch in on talks about lithium. No experience.

Have you used the 2v 500 ah before. Any experience in it . Then talk about it .

FEGEITOK:


Tell me more about your new baby.

Why this brand?

What are its specs?

ojeysky:


Till tomorrow if someone show me those 2v 2kah lead acid batteries, I will tell him what they are and why he should avoid them like plague but use lithium instead. Ofcourse he/she still has a personal decision to make.....! However what is annoying is for you to conclude that the action of mine is marketing for some personal gains! It's belittling and embarrassing!

GeorgeD1:


bros, you can choose to avoid them 'like the plague' but try give objective answers to upcoming enthusiasts.
you have a market to sell, no one is saying you shouldn't market what you have but objectivity is the watchword here.
you really don't have to be embarrassed if none of what is posted about marketers here refers to you.

@samninja

I hardly call ppu out sha

2v 10000000000000amp and 12v 100amp are all lead acids batteries. Same chemistry irrespective of volt or amp size.

At 12v at a considerable amount of amp it will take several hours to full charge it. Most times wat killed dem in d long run is undercharging....bc they are very huge. Now imagine u being a heavy user.

Banks can charge dem bc dey have other means of charging dem.

As for me, too heavy, takes space

I must not be a marketer to create time to input my inputs. Na just knowledge we dey find so appreciate ppu's input biko.

I dumped lead acids for lithium ( lithium ion and LifePO4).

GeorgeD1:


lolz. the new baby is actually a magnum ms4348pe inverter. it's the third installation
i'm carrying out since going solar. i needed a back up to my already existing inverter and this
came just in time. sege in benin made this happen. i contacted the regular sources while
searching but to no avail. i guess most vendors no longer stock them because of what's going
on with the economy.

samnaija:


They are not the the same chemistry but they are lead acid. Please do your research properly.
Lead acid batteries have different chemistry and make.

Gel batteries
Flooded batteries
Agm batteries.

Bro which of these different lead acid type did you use. Because experience is different.
Please tell us the type you used.

dollarnaira:



I agreed with different forms of lead acid but na still acid dey inside and u must float dem sha ni.

Mind u, u can buy d above,use it,and give us reviews rather dan waiting for one person to do d job.

I have used all d 3 forms mentioned above without waiting for someone else's reviews. Remember too that review is relative to how the user uses and charges his batteries hence, different lifespan.

I am currently using LifePO4 and lithium ion even without bms installed bc i am d bms . It is my choice rembr.

Advice: BUY WAT IS COOL FOR YOU.

As for me, I would rather buy a used lithium ion dan d best lead acid.

NA UNTIL U TASTE STH B4 U GO KNOW HOW FAR.

samnaija:


You have said it finish. Buy what is cool for you.
We all have different taste, but the truth is everyone goal is to have an operational system that will last.

From my personal view the 2v 500ah series are rugged and ok.
I am currently on tubular batteries and they are okay all lead. The key in renewable is having a enough battery bank that you don't worry about depleted bank .
Besides why change to lithium when your system is firing. Will keep reading from the side from people that have entered lithium.
And when the time comes to port I am very sure another battery technology will be out.

dollarnaira:


Yes ur system is firing but wat most are telling is dat, with lithium u will not pamper it like lead acid of 50% DOD ( na d annoying part b dat bro). So ur 500amp is just 250amp hope u know dat? Lets say it will last u 5yrs den it will die abruptly ( another annoying part).

But with lithium, after years of usage, plus several recycling it will depreciate to 80%. Which means u will just lose 20% after say '5 yrs'( assuming ni o). The battery go still dey fire. SO IF U ARE COOL WITH LEAD AT DIS STAGE, IMAGINE D UTMOST FIRING WITH LITHIUM. So, na dis last point we dey try tell u. Enjoy ur lead and let me enjoy my lithium in peace without thinking of replacement after several years of usage.

N.B Lithium titanate is out as d newest tech of lifespan of over 50yrs. This should tell u dat it is a lithium upgrade not lead acid upgrade.

ACID AND LITHIUM NO BE MATE.

mctfopt:
I think I'm on a wrong thread

Tommynaku:

Oga please take time to read my post carefully. I never said the inverter is compatible with lithium

GeorgeD1:
taking it's pride of place.
it couldn't have come at a better time.

mctfopt:


Magnum = Premium. Never seen it fail

I can only imagine the cost in naira

ObabyObaby:
Good evening all, Pls I need your help,Can I use 12pieces of 300w solar panel on 48v system, if yes what should be the configuration

Charge controller is 80a
Voc is 150
4pcs of 200ah
Inverter is 3500w
