TP5000 3.6V / 4.2V 1A DC 4.5V-9V Lithium Battery Charger Module

This is a charger module from ebay, it is based on the TP5000 charge controller, depending on settings it can either charge with 4.2 volt or 3.6 volt.

PCB size:21.5*14.5*4.2mm
Input voltage: DC 4.5-9V(Recommended not to exceed 7V)
Output voltage: DC 4.2V/3.6V(default 4.2V)
Output current: 1A(Default max)
LED Indicator: Charging-Red/Green Flashing,Charged-Green
Features: Charging for Lithium battery(4.2V) and Lithium iron phosphate battery(3.6V)

The charge current can be anything from 0.1A to 2A, this table shows some of the possibilities. Without a heatsink it is best to keep the current at 1A or lower.

R 1Ohm = I charge 100mA
R 0.2Ohm = I charge 500mA
R 0.1Ohm = I charge 1000mA
R 0.067Ohm = I charge 1500mA
R 0.05Ohm = I charge 2000mA

Support battery type
4.2v = Li-ion, Li-po, Li-CoO2, Li-Mn
3.6V = LiFePO4

Measurements
Power consumption when idle is 0.1 watt
Discharge with 3uA when not connected to power.
Discharge with 8uA when connected to power (5 volt supply).
Will restart if battery voltage drops to 4 volt (4.2V setting).
Will restart if battery voltage drops to 3.45 volt (3.6V setting).
From 0 to 1 volt it will charge with 0.4A (1A setting).
From 1 to 2.9 volt it will charge with 0.1A (4.2V/1A setting).
From 1 to 2.4 volt it will charge with 0.1A (3.6V/1A setting).
