Thank you for your answer. After some research on YouTube I found this precharge resistor.
They told me they couldn't found the exact model. I will told them to stick to the other one.
Hello, I'm buying 4 solar batteries of 51.2v 300a each in China. So each batteries will be 15kw. I told the manufacturer to add a precharge resistor to the BMS. They sent the information of the precharge resistor and they are waitingfor my confirmation.
I'm not an expert is this suitable for me?
