LiFePO4 battery charger 3-cell 3.3A

This is a charger for 3-series LiFP battery pack, nominally 9.6V (3x3.2V), which charge at 11 volts (3 x 3.65V). The bulk charge current is 3300 mA. It is a multi-stage li-iron LiFePO4 recharger with universal AC input. Includes a slow start feature and a 4-segment gas gauge.

These are state-of-the-art 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-iron packs.

General Information
Model PST-G60-12F3
Function 9.6V (11V) Volt battery charger for Li-iron and Li-Polymer 3-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 9.6V nominal 3-cell LFP battery
Input Frequency 50-60 Hz
Battery voltage 9.6 volts nominal
Battery size 3 AH to 30+ AH packs
Charging current 3.3Amps or 3300mA 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. 3.3 amps is applied to the battery until the voltage rises to 12.6 volts
Stage 4 constant voltage state until the charge current falls to 400mA
Stage 5. The charger turns off.
