I have this load tester with 5 units of 5ohm 1500w resistors.
I connect and disconnect manually to change current draw and want to connect all 5 to 5 relays and have 5 switches to increase the current with.
I'm using it with batteries up to 100V (24S).
So I have about 15A in average and 20A max at 100V for each resistor of 5ohm.
There are plenty of cheap relay boards on eBay like this one:

That go up to 30A but they are all rated 250V while if you look at the relay itself it says 250VAC/30VDC
Do you think I will fry it at 100V from a battery?
