In my own experiments, the R/C reciever outputs a 3V signal seemingly regardless of the supply voltage. Your controller will probably be putting out a 5V signal. It should be fine.

You can connect the battery to both devices by using a Y connector. I'm not sure if you can buy one, so you'll probably have to make one.

See if the BOE bot's PWM output is connected to the supply. Check if there's continuity between the supply lines on the PWM cable and the battery terminal. (check for continuity between the red wire and + battery terminal, then check for continuity between the black wire and - terminal) If there is continuity to BOTH, you can just connect the BOE bot to the speed controller without any problems.

If there is NOT continuity, you'll have to separate the BOE bot outputs from the supply. On the speed controller end, the supply lines on the PWM cable are connected to the supply. So, you'll have to make sure that you DO NOT connect the red wire on the BOE bot side. Well, it doesn't really matter which side is disconnected, just make sure that the power line doesn't connect the two devices. Having ground connected shouldn't be bad, and may actually be better.
