(Possible) New Controller
 

I have a question. On my Feigao 6s it says it draws 108 Amps. Is that constant or at full throttle? Would it be neccessary to run a controller of handling the full 108 amps continous or at a burst?
Any Comments aprreciated.
I have now decided to get a WATER-PROOF Speed Controller, I was looking at the Barricuda-125 or the Barricuda-80. I know these are boat controllers but would they work? If not does anyone know of a water-proof car/truck controller.
Also, Any suggestions comments welcome thank you.

The MGM Compro RC Car controllers come with a waterproof option, so you go for that. I wouldn't submerge it in water, but it'll do. That is probably 108 amps burst, so a MGM 80 should probably cover it, correct me if I am wrong guys. Personally I like to have some insurance, so I'd probably run a 120 amp controller:M:

My Mtroniks Pro controller handled it fine, that was reted to 80 amps constant or thereabouts. Its fully sealed & waterproof as well as being very cheap ($160) for a car controller.

I also have a Mtroniks Truck which runs completely cool with my 6s, but it does have a massive heatsink on the bottom so it should do!! (also waterproof, only $185).

Personally I would recommend against a boat/plane controller, or the MGM's if you want waterproof, as they're pretty exposed.

Your batteries would probably burn out before they could put out 80 amps continuous.

The amp rating on a motor doesn't really mean anything. It doesn't stand for continuous or burst, but is just a number that is assaigned to the motor.

IB3800s can easily provide 70amps continuous, as I have seen in an ongoing life cycle test in which a cell is charged at 6amps and continuously discharged at 70amps. So far it is at 16 cycles.

A 9920 would cover it too.

Metalman;

I've heard those IB3800's are able to deliver 250A peaks! (i don't want to know their voltage though) I was told by maxamps.
