In the past several years I’ve owned several different kinds of plastic Chinese cased battery packs, including a 13.5Ah 52v NCRb ‘Shark pack’ (reviewed here in 2016), and two 13.5Ah 52v GA ‘Shark Packs’ (reviewed here). I think I’ve replaced a total of 3 BMS’s in all these packs and I’ve replaced the plastic Shark…
Some ebike bloggers spend their time writing about bikes they have never ridden. This is not that kind of blog, instead, I spend my time using batteries, motors, and inverters to do things that I really should not be doing. In the process, I try not to electrocute myself or cause any permanent injury (I…
Last year I took a 3000W Cyclone mid drive ebike motor and mounted it on a wheelbarrow to make a high power machine that could easily move 500 lbs around the yard for about $450. I decided that it was pretty heavy and complicated and mused as to whether I could build a lighter duty…
3 years ago my good friend Laurence showed me a male XT60 connector that had shorted out by hitting something metal in his triangle bag. I had a good laugh at his expense and thought to myself ‘nothing like that is ever going to happen to me because I’m so careful’. 3 years later pulling…
For the last several years my wife and I have gone from a single tiny patch of Asparagus to having Organic and Permaculture garden and orchard that is well over 2 acres of cultivated land. We have hand grafted hundreds of fruit trees and moved many tons of soil, leaf matter and woodchips mostly by…
Everyone has been asking me “Karl, where have you been, we miss you”. My wife and I have untaken some huge projects which has involved moving massive amounts of dirt, woodchips, and seaweed on a nearly daily basis to fertilize our 500 fruit trees. We are also building a 700 sq foot greenhouse that will…
Eric from Lunacycle has a great scam going. He sends me new products for testing on his dime, I beat on them for a few months then eventually fall in love with whatever he sends me and end up buying it. I was skeptical about how I would feel about the new Wolfpack he had…
Ever since I started getting into ebikes I’ve wanted to build a high power torque sensing ebike. The main problem is that the more power you want to put through your motor, the more sensitive the torque sensing system needs to be. Although the ebike markets of the world are flooded with 250-350 Watt Torque sensing…
The other day I went out to the ebike shed to try to find something to ride. Much to my dismay, every single bike I owed was broken or out of commission. I had let my maintenance issues fall a little too far behind and there was literally 15 broken ebikes that I couldn’t use. I find…
Remember the good old days of Lead Acid when you could just throw your car batteries on a $12 float charger and then forget about them for years? How I long for those days. Welcome to the new era of Lithium batteries where long-term storage without degrading battery performance is not a simple nor elegant…
