Anyone remember a great thread that went through here about a year ago about rechargeable batteries.

There was an engineer from the aviation industry who gave us some really great information on different types of rechargeable batteries and the best way to charge them, battery memory etc…

I’ve done a search site and came up out blank.

Did anyone keep a copy of the thread.  I’ve got someone, I’d really would love to send a copy to.

Thanks
