HV questions - RC-Monster Forums

First thing to watch out for is that voltage rating. Is the ESC rated in volts only, or LiPo packs? A fully charged LiPo cell can be 4.2v, which would put you at 33.6v. Some ESCs tolerate higher voltage with no problem, but some go POP if you go a tenth of a volt over.

With that voltage, 84A is lots of headroom, so you've got no worries there.

Yeah, figured that the esc could handle it, guess that we will see. I could do 7s, I have a 3s and 4s 4000 pack. The esc is only rated at 40 amps, but at 8s would be over 1100 watts input power.

It would be better to use a Kontronik 55-10-32 instead of the 40-10-24. In Germany, many people use it without problems at peaks of 2,8kw on 10s Lipo in their Helicopters. I have also ordered one yesterday, look at the threads of othello, it works great.

The voltage on 8s Lipo should be no problem, some guys here in Germany use their Jazz 70 on 4s Lipo instead of 13v maxximum voltage and it works perfectly. The only problem could be that the motor draws to many amps when you are accelerating.
Hope this helps, sorry for my bad english
