Question
12 cells x 4.35 volt lipos on HV ESC ???? NEW BATTERY TECHNOLOGY

Can the higher voltage lipo packs be used in HV ESC's @ 12 cells ??????

12 x 4.35= 52.2 Volts ???????

12 x 4.20= 50.4 volts ?????

castle tech support says "don't exceed 50 volts" ??????

“Don’t exceed 50 volts” – exactly which of those words do you not understand?




On the serious side it probably depends on the voltage drop under load. If it quickly drops to 50 volts when a load is applied then you will probably be ok. I’m sure that Castle has some built in safety margin. A standard component voltage rating is 63v and that’s probably the rating on the internal components.

Most modelers will look at the ESC 12s rating and just charge up to 4.35v and go without a second thought. That’s something that Castle is going to have to deal with.


Let us know how it works out for you.

50V (or thereabouts) is the dividing line between low and high voltage. That has regulatory implications. There may be side issues with a power source like a battery where the voltage isn't a constant over the discharge, for what to take as the operating voltage-- it may not be the full charge voltage that drops pretty fast--not sure at all about that.

So perhaps it has nothing to do with component breakdowns (at least for these small differences), and more with what CC would claim the HV product is designed to handle.

Now I don't know this (what CC is thinking) for a fact, but it is just a guess on my part.

I'd prefer to not be the guinea pig

If the magic smoke is going to be released, I'd rather it be on someone else's nickel

I guess what I was inferring is that CC may never tell you it is ok, even IF the components can take it.

But I understand your point of view!
