EBIKE BATTERY EXPERIMENT - In the last episode we designed and built an ebike battery pack by using data from electric cars to transport me 89 kms on a single charge. In this episode we'll build a battery box to mount in the bike frame and install a battery power control circuit for the hub motor.

I needed to find an easy way to be able to sync video and audio when using a Zoom H4n Pro recorder during the editing process. So I built a solution.

I thought I would try using battery data from electric cars to size and design my ebike battery, plus demonstrate the technique I used to assemble it.
