Lesson learnt on fusing 12v side and sizing dc converter to FULL pack voltage 84v approx. So new contactor and d...

Re: Electric Drift Trike RWD

Is there any specific reason why you'd like to use a dual motor setup? If not, maybe you can have a look at what the awesome/insane Youtuber Colin Furze just did: https://www.youtube.com/watch?v=otlR05QZRrU Dual setup mostly because I have stub axles on the trike so just less fabbing involved.

Just wondering what the shaft diameter is on the 1000w motor?

Re: E-Drift trike motor. (Help me decide)

Hey rlynd3, have you seen the fiik drifter? Very nice low design with two 1000w bldc motors belt driven to each rear wheel. It gets your bum right on the road and no go kart style axle required. Only thing is having to double up on controllers I spose. I'm weighing up that style of build with a sing...

Re: Building first lipo pack - Drift Trike

I think a bms is still a good idea to low for automatic LVC shut down so that the rider doesn't have to be constantly vigilant on battery voltage while riding. Then I think you will have to engineer and build it. Those cheap BMS boards are designed for Li-Ion or LiFePO4, NOT LiPoly and their LVC's ...
