A very interesting test. Will these low voltage cells discharge faster than normal cells after they are fully charged?

The purchased inverter should require on-grid connection certification, etc. (comply with local on-grid connection regulations)

For those who have ordered 48V finished batteries, could you please recommend some brands and models? How about "Tewaycell 48V 300Ah 15Kwh All-in-one Mobile ESS Built-in Hybrid Inverter"?

Yes, the price difference is almost 2 times. Are there any professional installation technicians in the comments section? If you DIY this system for customers, how much is the installation fee?

Yes, 16 series 48V batteries😊

Regarding the 16S system, I have not purchased cells or accessories yet because I have been hesitant about cells and assembled battery before. 😅

Yes, for me, it may take several times or even ten times as long as others, because when I obtain the theoretical knowledge, I will search for verification again from other places, which will also lead to slower theoretical learning. But if I am determined to go ahead with the DIY 16S project...

Is your system also 16S? Or other systems? I usually have time on weekends to make my DIY projects, but I'm very, very slow at making DIY projects by myself.😅 I am still learning DIY knowledge from forums, Youtube, ect. And I know that the DIY knowledge I learned online needs to be put into...

I bought 4pcs EVE280K from Tewaycell before, and now I want to build a 16S system. At that time, I made the 4S system out of temporary interest. In this DIY process, I did not feel the joy at all😅. I just feel tired. And I saw on Tewaycell’s website that this model is no longer available in the...

I used a multimeter to test the impedance of the 3.2V lifepo4 battery, and it showed 15mΩ. But I used an impedance tester to measure it before, and it was 0.21mΩ. Amazing!🤣 And the seller told me that it is correct to use an Impedance tester to test. But she didn't tell me the reason.🤣😅

I recently saw some sodium battery videos on Youtube. I recommended these videos to my friend, and then he said he wanted to DIY a 12V sodium battery pack because he had seen too many videos of lifepo4 catching fire on the Internet!:ROFLMAO: Regarding sodium battery packs and lifepo4 battery...

If you buy complete battery 300ah from Tewaycell, I suggest buy the model shipped from China, this model will be equipped with active equalization. As far as I know, the European warehouse 12V 300AH model does not have an active balancing module from Tewaycell. I previously bought 2023 NEW EVE...

You can ask the seller for the specifications of the model you purchased, which should have the storage temperature. But now that the weather is getting warmer, you can place it in a cool, dry place. But this is not a long-term solution. After all, placing a bulging battery at home is like...

The battery itself can self-discharge, can it be placed in a low temperature area within the battery storage temperature range?

Please let me ask some more stupid questions😅 I just caculated it, If 3S 5P, the total solar panels' power is 4,950W, doesn't this matter? By the way, when connecting solar panels in parallel, do I need to consider the inverter parameter "Max PV input current: 50A"?
