6-cell lithium ion battery pack charger, 1.8A at 25.2 volts, removable AC cord, and fuel gauge

lithium ion battery pack chargers from PowerStream

Llithium ion battery pack charger 1.8A for 6cell packs

A 6 cell lithium ion pack has a nominal voltage of 21.6V to 22.2V and a maximum charge voltage of 25.2 volts. This is a 1800 mA multi-stage Li-ion and Li-po recharger with universal AC input. It is fully isolated, and includes a slow start feature and a 4-segment state-of-charge gauge.

These are state-of-the-art battery chargers. They use energy-saving techniques advanced charging precision. The slow-start function helps battery cycle life, especially with deeply discharged batteries. The charger is fully isolated from the mains, has universal AC input, and a removable AC cord. Will accurately charge lithium-ion and lithium-polymer packs.

Technical Information

Rated input voltage	100~240 VAC 50/60Hz
Battery type	21.6V nominal 21.6V, 22.2V 6-cell lithium ion or lithium polymer battery pack
Input Frequency	50-60 Hz
Battery voltage	21.6 - 22.2 volts nominal
Battery size	2 AH to 30+ AH packs
Charging current	1.8Amps or 1800mA peak charge
Charger type	Constant Current/ Constant Voltage precision charger
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, pre-charge function for deeply discharged packs
	Stage 2 bulk charge stage. 2 amps is applied to the battery until the voltage rises to 25.2 volts
	Stage 4 constant voltage state until the charge current falls to 400mA
	Stage 5. The charger turns off.

MTBF	30,000 hours by MIL-STD calculation
LED Indications	Power on, but no battery connected	Power LED red
	Slow start	The lowest green light is the only one on.
	Charging	Charging lights lit to show the state of charge
	Charged	All four green LEDs are on
	Reverse polarity, or shorted output	All lamps flash
	No battery connected	Red light is on, but no green LEDs
	Red light pulsing slowly	The battery voltage is higher than the charge voltage, so the charger is in sleep mode
