I tried to run a 3300/kv Bl and the Esc kept shutting down at full throttle, I'm thinking it might be the esc rev limiter thinking it's free running due to the high kv.

pulling to many amps thermaling.
the more KV the more amps. That esc is only rated for 45 amps, thats is what i have in my micro -
are you running that motor on 14.8 volts? If so thats 48,840 RPM
If that is what you are doing i would be happy there was a rev limiter and saved your esc.
If that is the motor you want to run try running the 2 batts in parallel and you will get half the rpm and alot happier system. But you need to stay under 45 amp drawComment

No I'm running it on 14 3600's integy intellects, which says after fully charged 20.562 volts...I assume those are unload volts.Samuel Johnson - “An injustice anywhere is an injustice everywhere.” William Cooper "listen to everything, read everything, and believe nothing unless you can prove it in your own research!"Comment

wow, you are almost exceeding the voltage of the esc for one and your rpms will probably explode the motor as well. You are running 55,000 rpm unloaded or 67,000 rpm if you held the 20.5v. At this point your going to blow up all of your equipment!
Question for you, how much rc experience do you have?Comment

I, use to run rc's years ago say about ten years, just getting back into as of this year, the brushless era enticed me once again. I ran that 3300 Kv in my Ep1 outboard SuperVee27 on a 4s lipo...It launches out of the water spinning a a range of props from a 632 to a 442 I had to make some trim tabs out of soft alum, so they could be more adjustable otherwise the thing would just tuck and roll all day.Samuel Johnson - “An injustice anywhere is an injustice everywhere.” William Cooper "listen to everything, read everything, and believe nothing unless you can prove it in your own research!"Comment

cool, welcome back
Keep a few things in mind kv multiplied by voltage equals unloaded rpm, running that many cells is not a bad thing, but how you wire them will change everything
wire them in series will double the voltage more stress on the cells
wire them in parallel and you will double the runtime less stress on the cells
try running them in parallel and see how it works both packs red wire connected to the esc red wire and both packs black wire to the black wire of the esc. It will give you 24,000 rpm and run for a long time that way. Props will also play into the equation but that will be increase the heat of the equipment so you will have to keep an eye on that stuff too.
Have funComment

Yea, your right, the motor and batteries were hot, but the Esc was super coolSamuel Johnson - “An injustice anywhere is an injustice everywhere.” William Cooper "listen to everything, read everything, and believe nothing unless you can prove it in your own research!"Comment

I recall reading before that it is not a good idea to parallel NiMh cells.Comment

Because of the weight. It's pointless.Comment

Iam new to all of this electrice talk and I just baught the BJ 26 and Iam haveing the same problem of not getting full throttle. I can only run the boat half throttle and Iam useing two venoem 3000 nimh pluged into the speed controller. What do I need to do?Comment
-
I believe there is a no load safety on the esc, if it see's no load it shuts offComment
-
Yea but it will go half throttle in the water.Comment

Maybe the low voltage cutoff has been set for lipo. The esc may not be seeing the right voltage and shuting down????. IDK just a shot in the dark.Comment
