I only had the chance to ride with my new Mega 60 battery a few times, and mostly on short trips, but I can already share my initial experience. I received the battery on time, and after unpacking it, I found a quality built, solid product. I inserted it into my Sur Ron (fits perfectly), connected the power cable, but I could not connect the communication cable, as there is no connection for that on the battery. And because of not connecting the communication cable, 2 yellow warning LEDs on the Sur Ron's dashboard started to continuously blink and I also received a 217 error code (CAN communication error). I am trying to get the information on how to get rid of these error messages. Nevertheless the motor works fine with the new battery, so I also installed the supplied extension on the battery cover (it looks like a 3D print), but it took me much more than 30 seconds, as I had to modify an Allen key (I had to cut it shorter) to be able to tighten the 2 screws on the extension. Otherwise it fits perfectly and as it is made out of 2 parts, the battery can be taken out from the Surron even with this extension installed (it is important when you want to carry the Surron on the back of the car). As for the range, my first trip was 39,2 km, with 1778m total ascent. Out of this ~20km was on dirt roads, where I was on almost full throttle, the rest was on single trails with steep climbs. I arrived home with still 23% battery power remaining. So overall I am happy with the battery's range, which is double compared to the factory battery.
