    T180 lvc

    I have just built a genesis with a 4074 2000kv motor on 4s with a seaking/turnigy 180a esc. The first run it seemed to be in LVC straight away so I changed it from 3.2v per cell to 3.0v I ran a different set of packs but it went into LVC after only a couple of mins and they were 5000mah 40c. Anyone else having LVC trouble on these esc's? I don't really want to run it without any LVC protection.

    Don't use auto detection, set it to the cells that you're using (4s). I have mine set to 3.2v/cell too and never had a problem.

      I have got it set to 4cells. The prog perameters I have is
      1. Forward only
      2. Number 4 which = 4 cells
      3. Number 3 which = 3.0v LVC
      4. Number 5 which = timing 15.00
      I will make sure my packs are freshly charged and give it a go again. I'm on an x642 prop and everything was nice and cold so I think I can prop up when I'm done testing.

        642 is alot of prop for that setup. Timing should be lowered too. I'm running 3.75* of timing (might go up one) with a 445 prop. That may or may not be your issue. Check your solders?

          It is surely not a lot of prop.

            I didn't think that prop was too much. I only ran for a few mins, 5 max and the motor was 25deg c and the esc was 28deg c. Correct me if I'm wrong. I was going to test on the x642 and move to the m445 if everything was ok.

              The Leopard 4074 2000kv is a y wind motor, 15 degrees is spot on for that motor.

                As Propper Chopper told me, set it to no protection and time your run times. Worked like a charm on me "dead" T-180. I also disabled the BEC as that was the first thing to hive me problems. Also made it act like LVC was kicking in. So now I set it to desired cell count, have external BEC, and no battery protection. Like I mentioned above, works flawless now.

                Hope you get it figured out.

                  It's not a leopard it's a turnigy XK-4074 2000kv but should be pretty much the same motor. I was impressed with the performance tbh. Still needs tweeking tho!
