These devices are all over eBay and I've even seen them in some videos. They seem utterly useless to me. Am I missing something or do these actually work?
It says the max charge current is 40A. Okay. Then it says the balancing current is 60mA. At 4.2v, that's what, 0.25W? Is it supposed to work by slowly bleeding off a tiny bit of juice over time, rather than "ok, your battery is at 4.2v, time to dump the 20A of charge current coming in".
Surely they have to do something as there are hundreds of them on eBay, and a lot of them are selling...
