Turnigy Marine ESC max operating volts

[petej]

I have several Turnigy Marine ESCs (120,A, 180A) and while the specs. state max voltage is 6S (22V), I have not used them with more than 5S (18.5V) in the Impulse with a Leopard 4074 1800kv motor and and Zonda Cat with 2075kv motors. Can these ESC truly operate/run on 22V or are they likely to fail at 22V?

You need to disconnect the build-in BEC and run a separate receiver pack. My personal experience with a 120A on 6s lasted less than two minutes because I was a complete newbie at the time and didn't know anything about proper set up.

I've blown up two 180A ESC's on 6s in the same boat.. Took the motors out too. Or the motors took out the ESC's Never did figure it out. The motors were Leopard 4082 1400kv & 1250kv in a 36" mono.
Admittedly I was using the internal bec. But I use the internal BEC in the Himodel GX200A 8s version that replaced the Turnigy 180.
I only use the T180 on 4s now.

I have run the t180 on 6s many on this site have. I never use the internal bec though. Running 6s t180 1600kv 4082 motors and all is great.

Thanks for your input.
Using the OSE calculators, prop, motor, etc., I calculate peak watts and configure everything to ensure neither the ESC or the motor would be exposed to their peaks watt or peak amps.

Running the 180 on 6s and internal BEC, never had a problem.

Ran t180 on 6s with a neu 1527 running a whiplash with no problems at all. Many races with the boat no problems.
