Discharge ports on both the Addmotor and FLX blade bikes were identical. Discharge ports on Both Frey Batteries were slightly different in that they had additional communications connections besides the main power connectors. This is actually better for future battery monitoring, but would not interchange with my existing bikes. So for me these "newer" "improved" plugs were not desirable.
I took a close up photo on mine and sent it to Frey along with my promise to purchase two bikes from them but ONLY if they matched my discharge port. They told me theirs was newer style and improved. I agreed with them it was newer and had other features for future, but that I wanted ALL my bikes to have interchangeable batteries.
They met my requirement no problem. Remember, Frey does not build batteries...they buy them and their supplier can put any darn discharge port on there that you require! No difference in cost to Frey or to me....
Right now my family has 6 Ebikes including (inlaws and outlaws) and 9 batteries and ALL are inter changeable EXCEPT my home built Frey HT 1000 that I built with Phase Runner controller, mounted external to the motor and a 60 volt, 50 amp triangle battery.
