/diy/ - Do It Yourself

i was out walking the other day and i found a broken hoverboard, the ones with 2 wheels. the aluminum frame was broken so thatd why i assume the threw it out. anyways, since then ive salvaged the 2 motors/wheels and thr battery pack, and i was thinking about bolting a sprocket to the end of the wheel and chaining it to my bike to effectively make an ebike. i have a few questions.
1. whats the best way to drive the motors? ive looked up videos of people driving them with just the 3 thicker wires, but do i need to use the 5 pin connector to use it safely? is it just 3 phase power? what sort of driver should i get?
2. how should i charge the battery? its a 10s, 36v li-ion battery pack made of 18650 cells. it already has a board on it, so could i pump 36v into it anf have it charge itself, or will i need a more specialized charger, like an imax one?
i appriciate any responses and there will be plenty more pictures posted
