Projectitis
100 mW
Hi all,
Sorry if this has been asked before - I have searched and not come up with anything yet, so feel free to point me at other threads if this is a duplicate.
I want to add a switch between the battery/BMS and the rest of the circuit (e.g. controller, 12v aux system) to kill all power when not in use. I have a 1000W motor and 48v battery, so theoretically around 20A maximum draw, so I'm thinking something that handles 30A at 48V.
Do I need something like a relay, or will a switch rated (for example) 20A at 110V work ok for 30A at ~50V? I'd much rather have a nice, relatively small rocker, than having one of those industrial ON/OFF panel switches too, that you see on table saws and other workshop equipment
For example -
will something like this be suitable?
I don't really want something like this!
Any ideas on suitable switches?
Thanks,
Peter
