Hi Guys,

So I've been harvesting cells for a few months now. I've got about 120 good cells (most have 2000+ aH) and my goal is to make a ebike. I got some question that hopefully you guys can help me out with. I'm trying to make a battery that can power my ebike so it can take me to work and back, and thats roughly 30 miles. I'm a big guy. I weigh 230 pounds (104.3 kg) and im 6 feet 3 inches (190.5 cm) tall.

How many wH should i aim for?

I'm goign to buy a conversion kit that has a 48V1000W brushless gearless hub motor. I believe i can make a 4.94 kWh battery (103aH * 48v) with 52 cell (103aH/2000mAh **roughly). Is my thinking wrong on this? is this enough?

Guidence appriciated.

Thanks.

EDIT:

Turns out i did my math wrong... I am making a 13s4p battery. So its 4 * 2000mAh = 8Ah. Then it would be 48.1v * 8Ah = 388.8wh. Is this right?
