Description and warnings
This is not meant for charging a battery from a USB Port from a computer. A USB
Port will only source 500mA max. If you want to use this to charge from a USB port
you would have to replace the resistor which is explained below. Even then, we
have not done tests to know if this will make using a USB computer port an option
with this board.
An ampere meter can only be connected to 5v input end of the module. When charging
it is better that the charging current is 37% of the battery capacity. So if you charge to the
battery of 1000mAH, current of 400 is enough. Make sure you use a proper gauge wire
for the current being used. Too thin and it will burn, too thick and the circuit may not act
correctly. Make sure the connection at the contract points are good. If the input voltage is
too high, like 5.2v, the current will be less than 1000mA, it is a normal protection function.
NO Reverse polarity, connecting the battery the wrong way will fry the chip.
The current can be altered (lowered) by changing the resistor connected to pin 2 of the IC
(at the bottom middle of the board in relation to the direction of the text). In the configuration
the module ships with the current is 1A. Changing out the surface mount resistor with a higher
resistance will lower the current. The chart below will give you estimates of some resistor to
current values:
| Ohms | mA |
| 30K | 50 |
| 20K | 70 |
| 10K | 130 |
| 5K | 250 |
| 4K | 300 |
| 3K | 400 |
| 2K | 580 |
| 1.66K | 690 |
| 1.5K | 780 |
| 1.33K | 900 |
| 1.2K | 1000 |
