    Good soldering, no trace of flux. Excellent module.R2 resistor with zero resistance attracts 12th contact (rtrick) chip tp5000 to "ground" (gnd), which limits the pre-charging current of 10% of the maximum chosen at the li-ion battery voltage below 2,5 v. If instead of zero resistance to stock resistor 50 kohm, the preliminary charge current will be 20% of the maximum selected. Accordingly, 114 kΩ will limit the current of 30%, 320 kΩ will give 50% charge current limits. When the voltage reaches 2.5 v, the charge current will increase to the maximum selected.If r2 resistor solder and leave contact 12 hanging "in the air", the pre-charging current will not be limited, it will be 100% maximum.The maximum charging current is regulated by r3 resistor and can take the following values: 1 ohm (100ma), 0.2 ohm (500ma), 0.1 ohm (1000ma), 0.067 ohm (1500ma), 0.05 ohm (2000ma).

The UCx84xA family of control devices is a pin-for-pin compatible improved version of the UCx84x family. Providing the necessary features to control current-mode or switched-mode power supplies, this family of devices has many improved features: startup current is less than 0.5 mA, oscillator discharge is trimmed to 8.3 mA, and during UVLO, the output stage can sink at least 10 mA at less than 1.2 V for VCC over 5 V.
