Read my post above.  The guy is an idiot telling people to do very dangerous things with Li-ion batteries.  You don't want to do this his way.  You are not missing anything of value in those vids.

Hi folks, well I can't speak about lithium cells, though I can offer some advice about lead acid batteries.
What I have found is that my 7 amp hour SLA's had been steadily dropping there fully charged resting voltage to about 12.4-12.5.
So I thought that probably the six cells within the batteries had become out of balance, so I discharged one till it could not light a 12 volt tail light bulb, then put a shorting wire across it for awhile, then ran a couple leds to make sure the cells had more equal discharge levels.
Then I used my bedini radiant charger and charged it up, it now sits at about 12.75 volts and with more charge discharges I can probably get this battery like new or better. Though this may not work with damaged cells or overly sulphated cells in relation to another. Hope this helps anyone.

Good info on LA batteries tyson.  Is your bedini radiant charger one you built or one purchased from Bedini/Aaron ?
