They say they have a patent pending, that should have more details. I would like to read it, can anybody find the filing?

pretty sure it's this one: https://www.google.com/patents/WO2013142964A1

basically the technique involves pulsing the current during (dis)charging, and optimising the length and timing of the pulsing in real-time, because the optimal settings change through the life of the battery.

I'm kind of a battery nut. I've been building various pulse chargers and capacitive current limiting chargers for years. Without fail all of my most promising pulse charge/bleed schemes that yielded faster charges and greater runtimes have done so at the expense of cycle numbers. Usually by a factor of 10 or more. I hope they've outsmarted this, but I have my doubts.

>Wow

and

>I don't really understand

in same post, what are the odds? :) Its a scam. They are tryting to sell 50Whr battery that can be charged in

>nine hours for 100 percent charge on a 1A power supply

from usb (5V), thats maths 101

>Do they have circuits that somehow manage the battery

They are selling product that stores more power than it consumes while being charged. Its snake oil at best, more likely a scam.
