Seaking T180 cuts out at full throttle?????

[boatbandit2]

Hi All
This is my setup 4082 2000kv leopard and a 180 esc with a extra 5 cap pack running silver series revolectrix 3s in series (6s)and I can run up to 3/4 throttle then when I hit full it cuts out and in about four times then I can get full throttle. if I hit full throttle from half throttle it does the same. I have tried to run auto calculate on the esc and 3.0 lvc and I have tried setting the esc to 6s.

Try removing the voltage cut entirely. Sometimes the voltage protection is a little too aggresive and causes the esc to cut out. Just time your runs.

Sound advice!
it is odd, because the 180 ESC is known to have LVC issues, and with packs that are prone to have voltage sag I would say your case is the same. But you are using Revolectrix----a brand that is lauded as being good at holding its voltage well among other attributes . How old are your packs?

Could just be the esc. I have a T120 that started going to lvc after a couple of laps, I suspect on inspection that it may have got a little bit of water in it as some of the sealant I put in the end of the heatshrink has pulled away. Has it had any water in it? Also what hull, prop etc. and are you using the esc's bec or running a separate batt for the receiver?

I am yet to find a T180 that works with LVC on.... so far removing it is the only solution. I don't think the LVC kicks in because of a voltage drop, but rather a flaw in the ESC/or firmware itself. You can always have a beeper/alarm installed to your pack/s if you are worried, or listen to the RPM pitch on the motors. When they start to loose performance, you can bring the boat in :-)

That will be a good explanation, I whole heartily agree, because none of my 180 has actually had this issue ( with LVC on that is ) and I was sometimes ( in the pass) using some pretty old and cheap cells like Skylipo.

Hi all
I have only done three runs with my revo packs, I have some trunigy nano tech packs and it does the same. I just go home from doing a run with the lvc off and my cell count on 6s and still having problems?
I am running it in a cf river cat with a x442 or a m445 balanced and sharpened . I am running a separate bec. It will only run 115 khp ,I am lost as I have had it running a lot quicker the 11khp and that is with it cutting in and out I will get my son to film it when I have him on the weekend or someone else if I can.

I haven't disconnected the red lead going into the receiver?

Thanks for the advice I run my boat today with lvc off and no difference.

I have not used a separate BEC , seems to me that is your problem. It would make more sense if you disconnect the red pin on the ESC. ( Get a short extension and do it on the extension).
My point is not to tell you what to do but to remind you of the extension trick that I learned.

Thanks a friendly reminder is good, I shall give it a go tomorrow.

I always run mine with the red wire disconnected. Also is your lipo cell count set to 6s? Sometimes ESC's can have problems if set to auto detect, but I forgot if the 180 has that feature. But if all those settings are applied and still nothing, try to recalibrate the throttle one ESC at the time (if twin)

[T.S.Davis]

I have 6 Seakings now and have not had issue with the LVC. Makes me wonder if there was a batch of weirdness or something.

I'll check my settings when I get a chance. I don't think they are off.

[Peter A]

I have two T-180's and have not had the LVC issue, granted that they only run 4s setups. LVC is usually set to 3.0v.
OP have you checked the timing setting, and are the caps still ok?

[revoltrunner]

the solder joints between your battery wires and esc don't look very good.
