Thank you for that it is greatly appreciated.
I will get working on this right away.
Driving range is the issue in an electric vehicle so 12 times longer on the load would be a great result for me.
I will persist with this and work on the issues you mentioned and let you know the results.
Here is an excerpt from someone who has worked with these relays before in an automotive:
As this graph (taken from the data sheet) shows, at up to 40 degrees C ambient the relay can handle 25 amps continuously. At higher ambient temps (like found in an engine bay, for example!), the relay is de-rated.
If high currents need to be handled, bolt the relay to a large heatsink (using thermal grease between the heatsink and the metal back of the relay) and check that the relay does not exceed 40 degrees C in operation.
