This item is on a pre-order basis and we make them in batches of 10. We will let you know when it will be available once we get your order. Feel free to contact us.

Engineering notes:

We are running 72 V batteries because they have multiple benefits. One being you need less draw to achieve the same power and therefore the amp hours will provide more range. If you’re drawing less amps then the cells are less stressed and therefore can provide more capacity. The higher the draw on a cell the lower the capacity is.

When a cell is lower voltage around 50% it’s amp discharge is lower as well which makes the last half of the pack more powerful if you are drawing less.

Watt-hour is capacity

Watt is power

W= Volts * Amps

Wh = Volts Nominal * Amp-hour

52V (14s) is 50.6v nominal
72V (17s) is 61.2v nominal

52V (14s) ah is about 21% less than 72V (17s)

52V (14s) 20ah = 72V (17s) 16ah
