The relay is LOW level input isn't it ??So far so good Although not mandatory, I would personally add digitalWrite(Relay, LOW);after pinMode(Relay, OUTPUT);
the motors will be hooked in line with the relay .
What EXACTLY is your relay turning ON?A previous post ..seems to suggest the motor POWER wires.
OK...So how much current?We are going somewhere with these questions....
I think that your going to need 2 relays.A 5V and a second... worked by the 5v relay ...rated @24v & 60 -100 Amp
OK.... you need a solenoid rated @ 100 amps.You will not find a 5v relay capable of 100 amps...so you'll need to use a 5v relay to work a second solenoid with 2 contacts ( both rated for 100 amps ) one for each motor.YES?Hence my statement ..

Fine ...just replace the two 12v motor relays in my drawing with the one 24v solenoid and use it to connect/disconnect the battery feed to the ESC.
No!! please do the math, a (rather) easy taskHint: the +-100A sensor sensitivity is 20mV/amp
@ Kas, can you check my formulas? milliAmp = 73.982 * analogRead(Apin) - 124755.859;
