I’m selling my new self made 10S4P Battery Pack. I used 40 Samsung INR18650-25R 2500mAh cells from a german suppliere. The Battery Pack has only one cycle of charge so it is pretty new. The cell cost me 137,50€. You can have the BMS too. It is already installed and working like a Charme. I have the invoice of the cells so if you are interested.
You can send me a whatsapp message and get a fair offer: 004367761259745
