If they worked, someone would be using them. Nuff said. There is no way they are twice as energy dense or give twice the cycles. Al On 5/8/2018 3:55 AM, Lawrence Rhodes via EV wrote: I have an eGo scooter and don't want to fuss with converting to lithium.  Are these batteries really twice

Lead-carbon has been around for 30 years in various forms. There is a good reason that lead-carbon has not been adopted by OEMs, RC modelers, cordless tool manufacturer, etc. They have high self-discharge issues, typical lead-acid sulfation issues, (even though some claim otherwise) and they

>From what I've read, these batteries have some characteristics of capacitors - most notably a rapid decline in voltage on discharge. I can't find specifics on how steep the slope is, but if it's too rapid a drop, you might have to add some kind of buck or boost converter to maintain a more
