Yes , i see what your saying it would have to be waterproof. The last thing we need is a water ingress problem on a Levo ?. I do think they should offer something along those lines though. But like you say I suppose it would need an existing port on the motor ( which it obviously hasnt )I think it's just coincidence. Shape will be similar to fit a bottle cage, like the many "bottle batteries" you can buy from China and other places.
And, unless they're going to be clever and have some coverable/self sealing power tool type power mounting built into the bottle cage, then it will need a flying cable.
I think it's identical to the Creo range extenders which were launched with the Creo.
