Hi, I want to find a solution to be able to cut the power directly without disconnect my 4S. So is this switch useable ?

It looks like that will probably work. If you try it, you should vet it by monitoring the heat buildup after some short operations before trying to drive around for a long time on it. They’ve also got a 100/200A model that should do better with heating. ---

Nice! Do you plan to use it with the BR switch? Can you order a termination socket with it that allowes you to connect them together? ---

Ok, i would like to use this one if it can bee used for this purpose. @rjehangir, what do you think? [https://bluerobotics.com/wp-content/uploads/2016/10/switch-4.png](https://bluerobotics.com/wp-content/uploads/2016/10/switch-4.png) ---

It’s not a good idea, this switch can be use with 5A max, and the BR consume 45A. ---

If you want to use our penetrator switch to control the switch that @bdevis, that will probably work. I have not studied their documentation, but it looks like there is a place to connect an external switch. You cannot use our penetrator switch on its own to switch the battery power to the ROV. ---

Hi @DavideROV I did not use the switches, just tested them. Was adviced not to so i put it ack again as original. Would recomend you to use a solid state rele for this purpose.
