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.

General Information
Model PST-G100-24L6
Function 21.6V (25.2V) Volt battery charger for Li-Ion and Li-Polymer 6-cell batteries
Type Battery charger for lithium packs. Can be left on the battery without causing damage, also useful for battery maintainer applications.
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.

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
