One thing I think the BlueROV2 really needs is a way to turn off the ROV power without having to open the battery housing and disconnecting the battery. It would be much easier, better and safer to be able to hook up the batteries on the bench and simply flip a switch on the ROV prior to launching.
There was a thread a long while back where some options were discussed, but no real solutions were found: http://discuss.bluerobotics.com/t/rov-power-switch-design/120/7
Blue Robotics offers waterproof switches but their current rating is much less than what we need to power off the battery. But it could be used in conjunction with a relay (or MOSFET?) for power control.
Has anyone come up with a working solution? I'm thinking the ideal location for both the switch and control circuit would be the battery housing. Thoughts? Ideas?
