All Jerry has done is repeat what is done when the cells are made. Why would that have any effect the second time when it didnt the first?
The people who get burned by lipos are those people who leave them fully charged, allow them to swell and then charge them at stupid amps or stick sharp objects into the cell allowing air to come in contact with the metal. Once the lithium comes into contact with air, it burns, especially if its already in an excited state due to having a lot of energy stored in the complex already...
While I would recommend using a charging pouch to put those people who hear the horror stories but dont have the knowledge to understand how it can go bad at ease, unless your cells are swollen badly, or showing signs of damage, I'd just charge them as you've chosen to before. The only way that cell is going to burn is if the lithium comes into contact with air.
