Not totally true Boss.
You can buy used sealed or tubular battery from someone you know to have a good maintenance culture and still enjoy it for the next three years or more.
Bigrovar sold his lead acid to someone after using it for about two years. Last year made it two years or more since the person bought those batteries from him and the battery was still waxing stronger.
When he wanted to sell his s for upgrade, we were rushing to buy them.
I sold my LA batteries last year after using it for about two years. The person that bought them is still thanking me till today.
Submission: If we want to buy used products, we should the source and make sure the owner has a good maintenance culture. This is the only way such products will last for us.

It is the maintenance that lithium don't really care about. This my 100a no no the house im branch.

He dares not f....k. up!!
The cells I got from him are well balanced too, no funny behaviour so far! The people I got it for used it to 2% at a time, but charged it up to 100% with 0.002 deviation at the end.

That sounds pretty impressive, I anticipate to give a positive .

Oh yeah, but old stock must be sold before the review

Dam5reey:


Not totally correct too,
Data communication does not make Good BMS...

So you cant parralle without Communication?

1. If your BMS does not come with the ability to communicate with your inverter and fellow BMS, it may be good, but not good enough. BMSes on lithium batteries are able to communicate with each other to synchronize charging and discharging.

2. No, you don't need battery communications to parallel batteries, however, it is good to have. It makes your batteries work together better. For dumb lead acid batteries, there may not be any need, but for smart batteries with smart BMSes, communications between batteries make for better overall experience and health of the batteries.

3. Finally, if it is so useless, brands like BYD, Pylontech, Seplo etc will not put it on their systems.

mvphenryeto5:


There's no how you can enjoy a used sealed lead acid battery cos you don't know how it was used, it might have only 20-30% efficiency left, to enjoy Lead acid you have to buy it brand New from reputable brand

Okay, you meant I should have gone for brand new Lead Acid?

You are missing the point.. topic is about parallel connection, not communication..

Valto:
I have 48v 6.2kw hybrid inverter, 120A Mppt 6500w pv capacity, fully editable and works perfectly with lifepo4 lithium battery

My hybrid 5kva inverter comes with an inbuilt charger. Do you think I might need to get an additional solar charge controller to ramp up its performance?

This thread Na for the rich.
Who no get money no suppose dey read am .

mctfopt:

TechGeek777 is indirectly telling us to reduce the price of our products.
He doesn't want to open up so that he won't offense us

mctfopt:

But if price of dollar should go up, you'd still sell old stocks at new price right?

The seller decides the prices of goods, but buyers decide who and where to buy from based on funds and other factors.

redgem:

Valid point, if price of dollar goes to 3000 $1, most of these prices will increase drastically!

This is a defacto sellers hub but there was a time people would funds to buy directly (cheaply) from China.
I almost bought Alaba fake s even more expensive than Fouanis Jinko(plus free delivery) right on this thread.

Dam5reey:

You may be the one who missed the point. This was his question. "I know LiFePO4 can be paralleled but I wanted to know if there's provision(PORT) for his battery pack to be paralleled like using RJ Connector to parallel both batteries."

Note the bolded parts.

The shipping route was narrow then, it's wider now.

redgem:

Yes Sir. It's a win and loose situation.
Most of us bought goods some weeks back when exchange rate was very high and some of those goods have arrived. What do we do now?
The market train is unpredictable, especially in Nigeria where exchange rate decides most of our business transactions.
If the exchange rate can remain at a lower steady rate for at least two months, the price will automatically be adjusted downward.

24v 100ah for 495k
12v 280ah for 745k

Why is 24v 100ah more costly than 12v 160ah?

ewizard1:

Yes

mvphenryeto5:

Because the 12v 160ah was an urgent sell. Lol

You need to open a new thread to accommodate average Nigerians like us, the guys here are related to politicians

What's the minimum / maximum s required for a 3.5kva 24v (450VDC), it's a Felicity inverter

mvphenryeto5:


Yes

I was glad I didn't!

then you should reply to him and not quote me.
