Setting the esc?

[785boats]

I think you'll find that the ESC does have a LVC. For NiMh or NiCd.
It's set at 67% of start up voltage. This is fine for a fully charged packs. It cuts out at about 0.9V/cell under load. However if the packs are 1/4 or 1/3 or 1/2 used when plugged in, then the packs will probably be over discharged before the 67% value of the lower startup voltage is reached. But the boat would be going notably slower at that stage & should have been brought in.
If the cutout is activated let the boat sit for a while & then idle the boat back on 1/4 throttle. Full throttle will just hit the LVC again, just like in a plane wltcol60.
Hope this helps a bit.
Paul.

Thanks, I have been going out with fully charged NiMh packs and come in when I notice a drop in performance. I think my esc is okay I might have a bad cell or two in my battery packs.
I did have a weld burn through due to arcing! Thanks again, Paul, for the valuable information.

how do you disable the brake then, i think its on on one of my sv's it beeps different

[wltcol60]

I don't know. On the AquaCraft esc it may not be so easy. On my aircraft esc's, different stick inputs can be used to program the esc. I only have one brand of esc in my aircraft so I don't know if the stick inputs are the same for the SV27 esc.

i was asking 785boats, cause he was the first i ever heard of this from. its most likely hold full throttle upon plugging the batteries to enter setup mode- but what from there

[wltcol60]

I posed this question to [email protected] so maybe I will get an answer. I hesitate to use my AC esc setting program on an unknown esc of unknown manufacture. My Aquacraft radio and electrical components are all marked "MADE IN CHINA", so I am rather dubious?

boatsupport@hobbico informs me that there is no brake programed or low voltage programed. If your SV27 beeps 4 times and runs normally, it shouls be okay! Thanks to everyone for yor input and help.

one of mine beeps once then 3 times and others beep once then 4 times

[6S HYDRO]

wait i know how to find out, that esc really is an elctrifly silver series 45a encased for waterproffing- i will lookup specs and program info on that.

I don't who makes AquaCraft components. I know AC esc's can be programed for Lipo's, Nicads and NiMh battery packs with throttle inputs.

really, than how

Good find on the specs 6S HYDRO.
Yes, I was going to say that if your motor Beeps twice when you plug in the batteries & twice when you pull the trigger instead of once then the brake is armed.
Note... do not run any ESC in a boat if the brake is armed as high voltages can be generated by the motor during braking which when added to the voltage of the battery can blow the ESC
I think those specs & instructions should be a sticky at the head of the SV27 thread.It would surely help a lot of people.
All the best.
Paul.

yeah thanks 785, mine does not beep twice at first but beeps different afterwards- wierd. cool name man im also a paul

[wltcol60]

Thanks Paul for the info.
