It doesn't do it when under load only when the wheel is in the air maybe its phase weakening I don't know really but it does 34mph with wheel in the air and its only on 12s those battery's are for my razor so when this gets its 16s 20ah its gonna be a handful 45+ I think the torque a dual motor will add is gonna be mental.l can't wait .
The controller is rated at 48v-1500w to 72v-2250w but it goes upto 2.8kw at 48v when at 120% speed its good value for money.
I recommend the shunt gauge I got to you it can control a sperate relay and you can set the max charge values and discharge it could have saved your controller from a nasty spike.
What PSU do you use I can not see hiw the spike made it to the controller in the first place, I use reclaimed server PSUs they have to be able to deal with spikes and keep delicate components safe they are built to very high standards never had an issue other than overload and safety cutout when running heavy duty car amps but I have a hp 12v 187amp version for that now £20 each and run a 1500w amp like a led no troubles at all.
