The deceleration only happens if i full throttle gun it already going fast… kinda feels like the battery isn’t providing enough juice for that burst. Once i let go of the throttle i can accelerate like normal
Its definitely the bms, diyeboard batts use bms for charge and discharge, too much currect back into the battery can cause cutouts (not related), surpassing the bms ratings for your bursts can also cause cutouts.
Let me tell you a little story. All those diye batteries with their lovely integrated bms’s are rated for the esc’s they are supplied with. Those esc’s only draw, note draw, the amps that they can cope with. You try to pull anything over 20amps per side and the bms will pop. Trust me on this. Just because its a 25r 5P battery makes no difference when the esc only draws 18A per motor. Chinese being the chinese will only supply a bms capable of those draws. They don’t care that you might then go and mate it up to a unity or focboxes capable of ripping amps from them in spades. The battery will rely on its shit cheap nasty bms to tell you to fuck off. I have killed 2p 3p and indeed 5p bms’s with after market vesc. Re wire the thing with a bestech charge only d140 and then you can up the draw to the batteries capacity.
