My BMS is showing a different voltage than my victron smart shunt. What could be the cause?

I see that most LiFepo4 cells have a charge rating of 0.5C which means for a 100ah cell, you can charge it at a max of 100ah * 0.5C = 50 amps. Since after a certain amount of cycles, the battery cells will degrade to only 80% of its original capacity, does the max allowable charging amps(50a in...

I have a 12V 100ah LifePo4 battery connected in 4s. On Amazon, I see a 14.6V 40A charger and a 20A version. I'm tempted to get the 40A charger, but am not sure if charging that fast will degrade the battery more and cause any heat issues. I'm using 2 AWG wires with a 120A fuse so I'm not too...

I'm using a BMS with a battery in a 12v 4s configuration and the BMS has a bluetooth function that lets me toggle battery discharge on or off from my phone. I was wondering if it is still a good idea to have a physical disconnect/kill switch or would it be pointless?

I'm building a portable LiFePo4 power bank for the firs time and was wondering if anyone could give an opinion/advise and possibly point out flaws if there are any. I plan to charge it through the PowerPole connection.

I'm charging up a 3.2V LiFePo4 cell with an adjustable converter. I have the voltage set to 3.65V and when I initially started charging, the output current was at 11Wh, but as it charges over time, the power output of the converter steadily becomes lower. Right now it's charging the cell at...

I just got my shipment of 4 "new" prismatic LiFePo4 cells rated at 3.2V each. However, one of them is only at 0.9V when I measured them. Is that cell permanently damaged or can I try to top balance it with the other cells and it'll be ok?

I notice that the 12V BMS from Overkill Solar has the option to include 3 soldered wires on each side of the BMS or an option to have 2 M6 threaded terminals on each side where the "C-" and "B-" wire holes are left empty. So if I pick the M6 threaded terminal option, will I need to solder a...
