2 amp lithium ion battery charger for 5 cell packs

A 7 cell lithium ion pack has a nominal voltage of 25.2V to 25.9V and a maximum charge voltage of 29.4 volts. This is a 1600 mA multi-stage li-ion and li-po recharger with universal AC input. It includes a slow start feature and a 4-segment state-of-charge gauge.

These are state-of-the-art fully isolated battery chargers that can be used on-demand, or left permanently on the battery for maintenance.. It uses energy-saving techniques and and and advanced charge 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 lithium-ion and lithium-polymer packs.

Function 24V (25.2V) 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 90-264 VAC, 50/60 Hz
Battery type 24V nominal 25.2V, 29.4V 7-cell series lithium ion or lithium polymer battery pack
Input Frequency 50-60 Hz
Battery voltage 24 - 25.9 volts nominal
Battery size 1.6 AH to 30+ AH packs
Charging current 1.6 Amps or 1600mA 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, precharge 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.
