I saw the Switch that BR is selling in its store. I like that it fits in the already made holes for the end caps and is sealed. I know it’s used for disconnecting power to low voltage devices…but I would like to use it as a main battery disconnect. Has someone rigged this up already? Normally yo…

[image] SHS: Installed two BR2 switches in paralell and hopefull it Will handle the current peaks. I’m not sure that I’d recommend doing this but I wish you luck all the same.

That’s not a good idea those switches are only rated for 5 amps. ROV2 draws much more than that, up to 90 amp peaks in full thruster gain

I am aware of this is a limiter due to max current peaks, but what is the biggest downside if it fails? I have been testing it and it seems to work nice, but i will not use it in 100% gain.

[image] SHS: but what is the biggest downside if it fails? It could potentially short out, over heat the battery and start a fire. That’s a pretty huge battery and steps need to be taken to prevent shorting it’s leads.

I have put it back to original again. At least i hade a lot of fun doing it. Will try to combine the swich with a relay instead.

Svein, that’s a good idea. You dont want to risk damaging that nice expensive battery. To be honest I have been working on this for a while now but have been busy with other ROV related projects. I will get back to this soon as I too would like to have a way to disconnect the battery externally. He…

I’ve assembled the parts to do this, just haven’t had the time to put it together. Hope to post something soon-ish.

[DSC_1880] [DSC_1881] I adapted a 200A relay to fit behind the electronic tray. Used the existing red power cord after the Pixhawk power supply and disconnected two of the small wires from the power supply. Downside is that I lost the info about power consumption.

I did a similar test the other day. I started with a 100Amp Solid State Relay but unfortunately the relay was “leaking” power through on the secondary side even when it was not energized. The Solid state had a consumption of 0.1 Amp during operation. I then did a test with an 120Amp standard car rel…
