LifePo4 Charge Performance
Thinking seriously about replacing our two GC2's with a pair of 100ah LifePo4's. Hearing a lot of chatter about how lithiums accept a charge much quicker than lead cells. Very familiar with how ou...

Hi...I'm attempting to choose the importance of the issues I am having with my new 12V 4 cell 80ah LIFEPO4 battery that I bought of Aliexpress and how to best continue while Im still ready to question the buy. It accompanied a 80a BMS with bluetooth capacity and Ive been utilizing a bluetooth application on my telephone to screen execution. I have completed 4 cycles on it up until this point and at present the best I have seen out of it is about 55ah. While charging, the voltage distinction between cells is inside 0.004V. As the voltage at cell 1 draws near to 3.4V, that phone begins to charge a lot quicker than the others and the overvoltage trips as cell 1 surpasses 3.6V while the other 3 cells are still scarcely enlisting 3.4V. During release, the voltage distinction is strong to inside 0.003V and as cell 4 methodologies 3.2V, it depletes a lot quicker than the rest and undervoltage trip is initiated as cell 4 arrives at 2.67 voltages while the other 3 cells are still around 3.1V.
You should start your own thread. Maybe brand of cells, did you top balance plenty of other questions.
You would get more useful help at diysolarforum.com it's orientated towards lfp build and more of the issues your quetioning about. Scoll down to Lifepo4 section. Here you might get speculation from folks that read about lfp but no hands experience.
