Need some advice...

I was going to put the solid state relay from conker 1 straight into conker 2 but the relay says that it is only rated to 30V on the high amp side. I am running 37V (10S) now so will this relay survive or do I need to go and get a new one?

If I do need a new one what can people recommend?

EDIT: Just had a thought could I run each S900 off a 85A botbits ESC?
