They would probably charge in like 2 minutes lol.
I sincerely hope you're not being serious. You are aware that lithium-* batteries require strict current and voltage levels?
You can't just throw more voltage/current at them to make the recharge faster - the protection circuit board won't allow that.
Circumventing the protection unit is a surefire way for a magnificent fireshow.

Sure you can, I charge lipo at more than a few C all the time.  Protection board, lol.  Like any large format lithium battery has an integrated BMS. 

Sounds like your thinking about laptop batteries.

Most non-consumer lithium ion/lithium polymer cells do not have a built in protection circuit, and they WILL take a charge at MANY C - This degrades the cell though.  In some cases, pretty seriously..

If you haven't witnessed the actual failure of a Lithium cell, consider yourself lucky.  They often fail in a spectacular way.
