DIY Battery pack

Image
I picked up a battery meter to test some batteries I purchased as well as some that I'm planning to repurpose. My initial reason for purchasing was to determine if the capacity of the batteries that I'm purchasing and shipping on a slow boat from China (3 months!!!) to know if the capacity of the batteries match the labeled capacity. This is important in order to understand what the battery pack will be rated in terms of amp hours. Update: Looks like that battery shipment disappeared and I will have to dispute the charges on that purchase. My 2nd shipping problem from AliExpress will more than likely make me avoid using them forever. The issue I have is not the frequency of failures (already high at 25%) but the length of time I need to wait before the shipment failure is confirmed (up to 3 months) My type c battery meter with 3d printed cover The other thing my attention deficit addled mind decided would be a great idea is to reclaim old laptop batteries to make flashlight upg

My experience converting an e-Bike

Image
I purchased a decent inexpensive "Nashbar Flat Bar Road Bike" ~$230 from Bike Nashbar back in April 2017 and rode it twice over the next 2 or 3 years. Life got in the way, I became even more sedentary.  With just a few months to go before I retire, I decided it was time to get back on the bike and spend my days being active walking and biking. Thinking that an eBike could help me up the hills, I figured I could probably get some more seat time for more exercise.  I found this reasonably priced kit on Walmart.com to convert my regular hybrid bike to an ebike for as little money as possible.  A new project with new stuff to learn will be a good time.   After looking at tons of options on Amazon and Walmart and trying to figure out if I should purchase a 48v or 36v motor, I decided to go small for my first project because lower voltage would mean fewer batteries, lighter weight and lower overall cost. I didn't want a front wheel drive bike though it might be slightly easier
