Recently upgraded Traxxas M41 boat to leopard 4082 X2 2200Kv with Seaking ESC 180A running 6S. It runs fine, nothing gets hot but at full throttle power cuts off. I can continue running but again at full throttle, power cuts off. ESC is programmed for 6S, low voltage at 3.4 and timing is 0 degrees. Prop is copper 42mm x 63mm. Batteries are 5000MAh 50C in series. Boat runs fine with stock ESC & motor.
Why is Power cutting out at full throttle

It’s not running “fine” if the boat quits whenever you peg it. Most likely the ESC is going into low voltage cutoff mode because your battery cannot supply enough voltage under load. Your motor really has an excessive Kv for 6S running, but if you insist on running it I suggest you reduce the KV to 3.0 volts. If that does not work, then either turn off the LVC and time your runs carefully - some controllers have faulty LVC circuits. Or, get a better battery with a higher C rating and capacity...not all battery makers are truthful in their ratings. Exactly what packs do you run?
Another comment, your motor is a “Y” wind, so you should be running 10*-15* of timing advance, not 0.

what Martin said.....I have some seakings and have the same issues as many others are. the voltage settings are not accurate and prematurely cutout
I programed the low voltage to the lowest setting....no more problems but you dont really have low voltage protection you think you have.
had a seaking 180 esc pop last week and I think I heard a cap pop but decided to not even try to fix it ....I will buy a new brand that actually works properComment

Thank you I'll lower the LVC and investigate the ESC in the other threads.Comment

In the past some that had problems with the 180a esc lvc cutting in to early lowered the voltage setting but it made no difference to the lvc cutting in. They even turned the lvc off all together & still had the same problem, remember if you turn the lvc off you need to work out run times & time them so as not to go to low on battery capacity.Comment

I would have thought that they would have fixed the problem by now. My son and I each bought the 180 speed control two years ago and they both have the same problem you describe. I really don't feel like spending the money for a new one So I have learned to live with it. Boat runs good at 90 to 95% throttle and I can even nail it, but only for 2-4 seconds and then back a little bit. Believe me when I say we have tried everything to fix this issue and nothing worked. My setup, 31" pursuit , leopard 40x82 1600 KV running either 5-s or 6-s battery 60 C. Not a over taxing setup by any stretch .Comment

They may fix the LVC issue on the next ‘run’ of ESC’s. But I’d be willing to bet the first run of those ESC’s was a substantial number. Especially since the predecessor was such an awesome seller. I haven’t tried the new 180’s yet as I’m still running the old onesComment

Most T-180 users find shutting the LVC off works best. If you have not tried this previously I would suggest it before buying a new ESC.Tyler Garrard

A 2200 kv motor is a safe 4s motor at best. Running 6s is drawing high amps and probably causing your esc to shut down at full throttle. That is not a sport set up and you should get a lower kv motor like has already been mentioned. I ran two 2200 kv 4070 motors in a 32" fighter cat many years ago at a saw event and got over 100 mph which was a record at the time. If your just trying to go fast for 3 or 4 seconds well you got a set up that will do it.Comment
