Hello, I bought a used E-Joe Jade 750 with no battery. Since I do alot of RC hobby stuff I thought I'd make my own. I used 16 Headway 38120 LiFePo4 8000 mAh cells. I've got a Daly BMS on it and just charge it with a 60V power supply. It works but I don't think I'm getting much mileage (distance)...
