I have just ordered a HakRC 16x16mm stack to build a 60mm footprint micro quad. I see conflicting info on whether this flight stack can handle 2S or not. Some pages list 1-2S, others list just 1S and there are reviews saying “blew up when trying to put 2S on it”
I would like to know what i can look at to determine if it can handle 2S? The ESC is rated at 10A, which would be a bit of a waste on 1S. Is it the MOSFETs that limit the max voltage? Or is it the onboard BEC that supplies the EFM8BB1 chips?
FYI this is the tower i got.
And here is a separate listing for the ESC part of it stating it is 1-2S.
I am thinking that if this little beast doesnt fly so well i would like to use this setup in a 2S build with 1103 motors, just wondering whether its possible maybe through the use of an external BEC for the FC
