Interesting. What about the efficiency? Does it give close to 7.1kwh? That is what made me to just buy bluetti, because I will be sure of the capacity. I have a locally made power station but I don't even get half of the rated capacity.

Your power station may have been built with the second life cells, if not third.
It's very unfortunate you didn't do a thorough investigation or much research on it before buying.
Quality grade B cells will give you the rated capacity and some will exit the rated capacity.
If you want to enjoy grade B cells, put an average load (0.25c-0.30c max) on it, otherwise be ready for another top balancing in the next 3 years or thereabouts, especially for those cells coupled with a passive balancer.

probably a power station made with disassembled 3rd life cells. our cells are brand new. all are capacity tested are above rated capacity.

Some persons will still buy 220a tubular(DOD 110a) with pampering for 280k instead of grade B 130a LifePO4 for 260k without pampering.

Eagba:

Thanks , but remove the battery in this equation. Is there a way around?
Let cloudy day be cloudy.

😂. You don’t want to run an efficient system. Why?

isn’t it a question of Quality? I assume the lifeP0 last longer

This isnt the complete price. U still av to get BMS, container/box, battery busbars, ?threaded rods and wood too. That's close to extra 70k upwards

Container box is not a must.
Bms types optional
How much is bus bars, u can even fabricate yours. Rest not important. Do you use LifePO4?

Once you get the cells with the free bus bars and a bms (there are cheaper ones), then your battery pack is ready for use.
Some of us do help our customers to top balance the cells before sending to them.
Compression is optional. It's very necessary for those that are coupling cells for sale.
1. It makes the cells secure by being tight during transit.
2. It takes care of the normal expansion that occurs between low soc and high soc which Eve says is about 0.5mm per cell.
For diy guys with a proper system design that are not pushing the cells anywhere near what an Ev system would, then they have nothing to worry about compression.
Their concern is Calendar aging of the cells only.

Be like u wan fight me with this ur question. Just making my point. To each man his own. If u av kids around, then a box is a must unless its in an area they cant access. And yes I use LiPO4 and its bin sweet. Fabricated my box as I got just the coupled cells wit bms from oga Valto here 😁

Boss, let's try to educate people as much as possible.

Container is must, LFP Batteries can push a lot of Current..
BMS should not be optional,
Quality of Cables must be able to Handle 0.5C without Warming up that. I tested a pack today at 1C discharge temperature of all components (BMS, cables, Terminals and busbars) did not rise more than 45°C.

You didn't get me well.
Bms types optional, not bms optional. Bsms Bluetooth and without; 100A bms on a 100a battery is a waste to me.
There is a short length original flat copper not up to 50cm sold for close to 10k. I don't generalize I say what works and still working for me. I love alternatives rather than depending on common materials that can be easily faked. But both of us know that 1C is for few seconds. Some won't even smell 0.5C as we all run different loads. Why do most cases have vents? My solar panel cables is not the regular cable everyone goes for...well, thats private. It handles close to 30a without warning up. I am not the conventional person I go for unconventional materials that work. Lastly, this forum is for those with common sense - you pick, discard, use or reuse information online. Life no suppose hard.

Good day all,
please who have a review on this PowMr hybrid inverter?

Good evening DIYers. Please bare with me, it's a long read.

I think it's time to bring this to the larger house maybe I'll be able to get tangible help.

I purchased my first lithium bank from the Jos guy (jemag) in December 2022. The capacity of the bank is 24v 110a. In August last year, I purchased another battery bank 24v 100a from @valto.

I already noticed that my first bank had a hard time running from night till morning. On most nights it does by 2am. Reason I opted to purchase a second bank.

My night time load is between 100 to 200w (two 60w standing fans). So at the very least, I expected the Jemag battery to last till morning.

The way my system is setup, I have 1.2kw and another 1.8kw on both sides of my roof. Each set of panels go to their individual CCs before going to the batteries.

I began noticing significant deterioration in March this year. The battery may be full but shuts down within 30 minutes after a 200w load is introduced.

Upon closer inspection, I noticed there was a bad cell inside. One of the cell drops from 3.2v to 2.4v within minutes, triggering the BMS to shut off.

When I contacted the Jos guy, he proposed sending the bank back to Jos from Port Harcourt, an unnecessary step if you ask me. I opted for DIY, opened the bank and saw that one cell was seriously swollen.

I notified him again but he was angry on why I opened the battery. He was particularly about sending the bank to Jos for them to compress but I refused. This guy barely responds to messages.

Mind you, he used Sinopoly cells to build the bank. I asked if he had a replacement and he said yes, I paid around 50,000 for the replacement in May 2024 only for him to call days later that the cell they found was swollen but in perfect condition.

With no alternative at hand, I asked him to send the so call battery. That was a mistake on my part. When it got to me, the rating was not only different (3.2v 200ah) but the battery was worst than the existing piece.

I decided never to contact him since he never checked back. I abandoned his battery since March.

Now to my question:What can I do to salvage my battery? Do I sell of as scrap? Are there buyers?
