Charging a Lithium 18650 Cell using the TP4056

Using a very cheap single cell lithium battery charger module based on the TP4056. For less than £1 you can make a safe and effective lipo battery charger. The UltraFire cell used has a very low energy capacity (much lower than the stated 3000mAh) so charging should have been quick, but an interesting side-effect of its high internal resistance may have slowed down the charge time.
