I just found a local dude with a zeus. I can’t confirm what cells they are but I thought they were Samsung 48G. The thing was lacking in torque at the beginning (could just be throttle curve set) but the tkps felt really nice and stable. The dude who brought it hit 37mph on it according to my freesk8 robo and was keeping up with me for the most part. I was pleasantly surprised.
He bought a stormcore 60d without measuring if it would fit though so that’s going to be fun…
