								  | Charging algorithm This is the
									 "European" charge algorithm that does not float charge the battery at the last
									 stage, but still keeps it maintained. (see the graph below)
 | Constant current/constant
									 voltage | 
 
								 
								  | Stage 1 slow start, precharge
									 function for deeply discharged packs | 
 
								 
								  | Stage 2 bulk charge stage. 2.8 amps
									 is applied to the battery until the voltage rises to 16.8 volts | 
 
								 
								  | Stage 4 constant voltage state until
									 the charge current falls to 400mA | 
 
								 
								  | Stage 5. The charger turns off. |
