I want a contactor so I can connect it to the stock fuel pump relay which shuts down in case of a crash.
Good idea - I like to see an inertia switch (which is often in series with the fuel pump relay) shut down power to the controller and any additional contactors in the battery circuit.
I strongly recommend that any additional contactors installed in the battery circuit either be the Tyco/Kilovac EV200 or the equivalent from GigaVac (which was started by former Kilovac engineers when Kilovac bought out by Tyco, btw). DO NOT USE contactors with low DC voltage ratings (ie - for golf carts, yachts, etc.) or, worse, ones intended for use with AC.
If the cost of the right contactor is a bit too much to swallow over there then a more budget-friendly approach is to put an appropriate DC-rated fuse in series with the positive line inside each battery box (I like Ferraz-Shamut [now Mersen] A50QS series fuses).
Good controller choice, btw...
