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 panels 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 verify the source and make sure the owner has a good maintenance culture. This is the only way such products will last for us.

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.

TechGeek777:


Nice, I pray dollar continue to crash for massive discount.

Other vendors should review their prices.

1350 now for $1.

Dam5reey:


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

So you cant parralle without Communication?

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

adrusa:


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. Premium BMSes on premium 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, premium brands like BYD, Pylontech, Seplo etc will not put it on their systems.

Valto:

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

redgem:


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

Dam5reey:


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

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

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

mvphenryeto5:


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

Yes

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.
