The board is a universal battery charger for 1-Cell Li-Ion/Li-Polymer (3.6-2.4V) and LiFePO4 (2.5-3.6V). It suits all types and sizes of Lithium batteries.
Various chemistries are acceptable: NCA, NMC, LCO, LMO, LTO and LFP
It has integrated current capability up to 800mA. The board is designed to supply a maximum of 700mA.
The device has three phases for charging a Li-Ion battery: precharge to recover a fully discharged battery, fast-charge constant current to supply the bulk of the charge, and voltage regulation to reach full capacity
Automatic Sleep Mode for low power consumption: 350-nA battery leakage current and 85-µA input leakage current when charge is disabled
It has an NTC thermistor to monitor battery temperature and controls the current accordingly or disables charging.
It has two LEDs to indicate the charging status or faults
It has a switch to select between LiFePo4 battery and others
The battery container suits the protected and unprotected 18650 batteries
