Llithium ion battery pack charger, 50 watts 1.7A for 7-cell packs

7 cell lithium ion packs have a nominal voltage of 25.2V to 25.9V and a maximum charge voltage of 29.4 volts. This is a 1700 mA multi-stage Li-ion and Li-po charger with universal AC input. It includes a removable AC plug, 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 C14 style AC cord. Will accurately charge lithium-ion and lithium-polymer packs.

General Information
Model PST-G100-24L7
Function 25.2V (29.4V) Volt battery charger for Li-Ion and Li-Polymer 7-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 25.2V nominal 25.2V-25.9V 7-cell lithium ion or lithium polymer battery pack
Input Frequency 50-60 Hz
Battery voltage 25.2 - 25.9 volts nominal
Battery size 2 AH to 30+ AH lithium ion battery packs
Charging current 1.7Amps or 1700mA 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 29.4 volts
Stage 4 constant voltage state until the charge current falls to 400mA
Stage 5. The charger turns off.
