Battery and Chargers

BBS needs to calculate the return home low battery based on payload, distance and elevation like XAG platforms. XAG's method makes the operation far safer as the drone will never run out of battery on the return path. It will automatically start RTH at any state of charge based on many factors, rather than begin RTH at a set percentage.

Does anyone have a way they have found to more easily swap the batteries out of the drone? I have found since the fill cap is located at the rear of the drone it is best to land with it facing away from the operator for easy fill access. The issue is pulling the batteries out especially the more forward battery. It requires a firm “jerk” to get them out and you are reaching across the drone to do it. This really hard on the shoulders as you are doing an upright row type of move bending over the drone. Any others have this issue or have a better way to swap?

The cable come with charger need to be 240V
