Senton Need help, my senton puts on the breaks after about 15 mins of running

[Don mercier]

I ran a 2s in it for about 15mins and then it sounded like the breaks went on. When i got too it the fan was still on and steering still working. So i shut it off and waited 10sec and turned it on, it took off and did the same thing, is that thermo protect mode?

low voltage cut off... the battery is flat..

LVC.

The 2s bat lasted 15mins, but my 3s only lasted 10,

What's your mAh and C ratings ?

What's your mAh and C ratings ?

My 2s is 5000/50c... And my 3s is5000/35c

My 2s is 5000/50c... And my 3s is5000/35c

I was told not to go less than 30c with a 3s blx

I'd get yourself a battery meter as that will tell you what condition the batteries are as well be able to check individual cells for faults.

Those should be fine. Hard to believe your run times are that short. You running in grass ? That really kills my run time.

Hi Don,
More than 221 degrees? (cf Arrma manual)
From our latest experiences on our "new" Mega BLX 3s mod, when my son do the 2s (7400 Mah) followed by 3s (5000 Mah) combination the motor becomes extremely hot... From this date, we did not have any red light blink, but will need motor fan for this summer track sessions.

My 2s is a gen ace, and the 3s is a venum

Would it be better to get a higher c battery

What they are saying is you've hit LVC(low voltage cut off) or Thermal protection on the ESC
Charge your battery and let the truck cool then try again.. youll see it'll run normal untill the same again, LVC or THP

What are the packs voltage when it cuts out? What is the temp of the motor and/or esc when it cuts out? That's how you tell if it's thermal protection or LVC. Get a lipo alarm if you don't have one they are cheap just to see what the voltage of the pack and/or cells when it cuts out. Get a IR temp gun (if you don't already have one) and check the temp of the motor and esc when it cut's out.

The motor was warm too the touch and esc but didnt seem all that hot its only 40° out. I did get my bat wet could that be the cause?

Hi,
In this particular case, I don't know.
But, we don't have any battery below 50c.
