Morning All. Yesterday I was trying to fit a mid drive kits with 36V 16a Battery from Pandaebikes which I bought just before X'Mas. After the battery was fully charged I checked the voltage. With red to+ and black to- which read -41.7. I had Email Pandaebike will it be safe to connect the reversed polarity to the motor unit. They ask for the photo of voltage reading showing polarity I am measuring. Photo sent, waiting for them to come back. With knowledge peoples in here. I wonder is it safe to connect a reversed polarity battery to the motor unit.
