For Contactors 1,2,3 I am thinking TE EVC 80 contactors or the solar contactors. Need to check prices and find digikey/mouser links. Apparently these contactors are only available in Europe and only on special order from TE. We should be able to use the contactors that we have in the bay that were used for previous cars. They are on the shelf above the electrical bench right now. We have 4 of them, but only 1 has the contactor sense coil. So we still need the extra contactors.
Switch
We should be able to manually turn the battery on or off. Should be rated for at least 20A, probably more for a safety factor. Should also be satisfying to turn on - big switches are nice.
...
Should we have the option of switching in a larger current sense resistor to measure the current more accurately - then we might not have to change current set points when switching code as the reading scales according to the resistor chosen.
We have a couple extra current sense resistors around the bay, so we should use one of these.
