Another vote here for the HobbyWing Quicrun ESCs, I also use their Seaking for higher ampages.

Annoyingly though you can't use the programming card on the 30amp ones and I had use the beep method!

Re: "(C rating). How many times the capacity the battery can stand being pulled at any moment."
Just a note to clarify what this actually means😉
C rating is not a function of the capacity itself, usually expressed as X000mAh for marketing reasons, looks better than XAh🙄 But of the capacity in mAh expressed as Amps.
E.g. a 5000mAh (=5Ah) capacity battery rated at 50C can allegedly deliver max 50x5=250A. BUT for how long? Maybe 1.2 minutes if you're very lucky. (5/250)x60.
But at least it has a short term reserve current capability. If that helps? I don't know.
If the motor stalls a correctly rated fuse, or a high end ESC with temp/current protection should obviate such high currents being needed.
Cheers All, Doug😎
PS I also like Hobbywing QUICRUN ESCs (1060 for brushed, 16BL30 for brushless).
Their programming card makes brushless set up a doddle. No messing about with beepy de beeps😁
Young at heart 😉 Slightly older in other places.😊 Cheers Doug

Try to get the rating (current) for the motor under load and match this to a suitable LiPo (C rating). How many times the capacity the battery can stand being pulled at any moment).

ESC cut-off is related to LiPo protection (minimum voltage) and not brushless. Some can be configured via software/programmer/DIP/jumpers to different cell types.

To make sure things function as expected talk to a local supplier, bite the bullet and jump for Motor, ESC and LiPo(s) in 1 hit.

Good luck 😊

This applies for hobbywing where you have to switch to the preferred battery type and where you have to program the ESC

Also be aware some brushless speed controllers have a low voltage cutoff threshold. Could potentially leave you "adrift" should your brushless motor pull your NiMH down too quickly.
Some programmable controllers also have battery "type" selectability.

I’m not 100% sure on this one but my understanding was that Lipos can better withstand the higher discharge loads that a brushless motor will place on the pack. Like I say, I am not totally sure and others will certainly know better but you may find that your voltage under load drops more with a nimh and that the pack discharges a bit faster than with a lipo. Personally I have only used Lipos with my brushless setups.

My personal opinion is that lipos do need more attention in comparison with lead or NiMH batteries
NIMH keeps the middle in weight between lipos and lead. I changed from lead to NIMH 2 years ago and I m very pleasedwith the result.

You can use 'normal' batteries Phil. NiMH batteries are fine. Lipo's deliver the same power from a smaller and lighter pack.
Have fun 😉

Hi guys I am using a brushless motor for the first time, I have bushed motors with ni-mh batteries do I need to buy lipo batteries or can I use my normal batteries, I know it is probably a dumb question but I don't know the answer 😂😂
