There is of course a finite limit to the trigger circuits fan-out capability but I have no idea what it is. I have had this concern myself when adding a second battery. A simple way to avoid increasing the current drain on the trigger circuit is to not use the trigger circuit for the added relay. Just connect a wire from the high current output of the stock relay to the trigger circuit input on the second relay. This small added load to the stock relay would be very minor and this method helps isolate the stock wiring from the high current auxiliary battery wiring.
