You need a more capable battery. If 40A causes such a voltage drop then it's more like a weak OEM battery for 750w or maybe 1kw.
yea but expensive!

Yet my problem or the thing i cannot understand is why this low voltage only happens after a long freewheeling (say 30s or more ). At all other times even at the highest speed, full throttle, and full max cur. Amp, I never saw the voltage drop below 57V. It is only happens after free wheeling/coasting of the 30 ec, regardless of whether the regen is on or off.
