Hi! Can anyone explain to me why my B6 V2 balance charger and 3 other battery check controler shows that there is only 3 sells in my battery. My ST 16 shows that there is 14,6 volt in the battery. When i bought my copter it says the same so i returned it and I have got a new battery from Yuneec. It is the same only 3 sells. I dont understand this. Thank you
