Charging a lithium polymer battery?
If i have a lithium polymer battery with the protection circuitry could i just charge it with a 3.7v current without a special charger

Those are good answers. Possibly, but the protection circuity likely looses some of the voltage, so 3.7v input likely is not be enough to fully charge your lithium polymer battery. Fast charge is one of the advantages of lithium batteries. Better chargers monitor the temperature of the batter and reduce the charging current. by about ten times, if the battery is getting hot, or the terminal voltage exceeds about 5 volts = possibly 4.2 volts is the industry standard max terminal voltage, even at one ma charging rate.

NO You must use a proper charger that knows about charging IiPo batteries, haven't you seen the many stories on the news and Internet about fires in device while being charged?

Get it wrong, and you'll have a difficult-to-extinguish lithium fire on your hands.
Experts only when it comes to designing lithium battery chargers.

TO CHARGE ONE PIECE LITHIUM CELL REQUIRES A POWER SOURCE NOT MORE AND NO LESS THAN 4.2V. ANY HOME MAKE POWER SUPPLY HAS VOLTAGE REGULATOR TO SET OUTPUT AT 4.2V IS FINE TO CHARGE IT.
