Felicity Solar Lithium Batteries

i checked the numbers on the floor of my crates(2 batteries). they are 30.2 and 44.6
i am getting around 20-21 kwh combined for cells that should contain 30kwh

i checked the numbers on the floor of my crates(2 batteries). they are 30.2 and 44.6, i dont think any of those are the real capacity.
there's also a strange X below them.
i am getting around 21-22kwh combined for cells that should contain up to 27kwh so i will try getting an adapter so i can connect the serial port to my computer and check the edms data
Well it could be that the capacity is 230.2ah and 244.6ah which would make total 474.8ah = 24,3kwh

Fun fact one of my clients crate had 96.3 written. And that gives me the full 15kwh cap. Also the working voltage of that one seems to be higher around 53 underload

So it was up to luck, and my luck is the worst.
My batteries should have been labelled as 12.5kwh/250Ah instead, or grade B 300Ah because thats what they are.

Did you check it with the communication enabled? The bms parameters are fairly conservative.
I agree, they are lying and if you confront them then they know nothing.
You could check for the numbers that is written inside the battery units if you open the right side panel. I get about 14kwh from mine when discharged to 44.2v which is about 276ah

i ordered an RS485 to USB converter. it will take a few weeks to arrive.
i cannot open the battery because it would void the warranty as per the contract.
 
Hello guys, this thread is very helpful but no conclusion was reached on felicity LPBA or LPBF batteries, what is the final verdict for this brand? I have a budget of around $2500, I am looking for a reliable long lasting, one-time solution battery with a 10kWh or 15kWh capacity.

I have also found this guy selling DIY batteries here: https://www.dubizzle.com.lb/ad/lithium-battery-solar-ID115719646.html
What do you think of his work and what should I ask him to know the quality of his cells?
 
Will do, have to charge each battery individually to full capacity. Then wired up it in parallel and let the entire battery bank balanced itself before wiring up to the Deye 16K. This will prevent SOC run away, which I'm experiencing on the 5*200A battery bank now, where the Voltage across the bank is fairly close but the SOC computation not balanced. The factory engineer suggested the battery to be individually charged to full 100% SOC and cut off, wire all entire battery bank parallel and let it self balancing to resolved the SOC calculation not consistent.
