The voltage checked by VAT1100 isn't precise. I have one multimeter and three watt meters which I believe they are within the margin of error. VAT1100, however, is 54.3V while mine are indicating 54.6V~54.7V. In current, VAT1100 is a little bit high. Frankly speaking, I think there is a possibility that all of mine are wrong but yours is correct but from a commonsense standpoint, there's a good chance VAT1100 is not precise in voltage and current. Lastly, the hole of VIN is too small. It has barely enough space for AWG 14 wire. We usually use AWG 12 wire for 750W motor and 48V li-ion battery. To my regret, the VIN hole of VAT1100 doesn't have enough space for it. Any ideas for me in this situation are welcomed.
