???? Coordinates X-HX0598A capacity measurement module Lazada ???? https://s.lazada.co.th/l.1sXR Shopee ???? https://shope.ee/1VRDQVeDJA Hello, welcome everyone to the ZimZim DIY channel. Today I bought a module to use as a lithium battery capacity test module. It measures the battery capacity without guessing. Measure it live, measure it for you to see. This module is for use with only 18650 lithium-ion batteries. Therefore, today I will demonstrate various uses for my friends. First of all, if we look at it, we will see a TFT display screen in the middle of the screen. And there are 2 10W 8 ohm parallel resistors, which will work in conjunction with the Dischage mode because the capacity measurement must burn the battery power here. So he screened it here that its temperature while working may be around 60 - 80 *C, which means it is hot. This part is the switch to turn on / off the machine and has 3 control menu buttons below. The left and right buttons are the battery slots for 18650 batteries. Normally, they will use only the right side of the battery to test. It says Test 1 here. I will remove the battery from my sensor light module to measure the remaining capacity for you to see. In fact, it is not broken. I have been using it for a year and it is still working fine. After removing the battery, we plug it into the battery slot like this. It is ready to work. Or another way, if it is not convenient to test a single battery, you can receive input from outside and test it at Port Test 2. But you may have to remove this battery first. Oh, then what is the other side of the battery slot for? On the other side, he said to use it as a power supply or supply power to the device only. It can't be charged and it can't be discharged. Let me try turning on the device for you to see. If the board does not have a power supply, the device will not be able to be turned on. But if I plug in the battery and turn on the device, the device will work. The question is, what if we only have one battery and do not insert it? The answer is yes, you can use a Type-C phone charger adapter to plug it in as a power supply. Observe the screen. Now, it will show the battery voltage value, which is 3.39V and the battery resistance value is 78 m Ohm. Next, let's look at the buttons. The first button is the mode selection button. At first, it will be auto. Press it until it lights up once, then press it again, it will change to CHG mode. Press it again, it will change to DSG mode, and the final mode will cycle back to auto mode as usual. For the first mode, we will look at CHG mode first. To make it work We need to rely on the second button. The second button is easy to think of. It is the Start and Stop button. At first, the status will be Stop. If we press it once, it will change to CHG status, indicating that it is starting to charge. I will let it charge until it is full or the status will stop charging until it becomes Stop. The numbers that are running and showing on the screen now are 1. The battery voltage at that time 2. The charging current 3. The total wattage and the time used. The voltage here will increase continuously, increasing to a voltage of about 4.2V. As for the current flowing here, if it flows below 100mA ... when will it stop working? It is considered that the battery is full and the status will show the word Stop. I will leave it and wait to see how long it takes. And don't forget that our battery still has some power. It's not completely depleted. Now, after 10 minutes, the voltage has increased to 4 V. After 30 minutes, the current is still almost 1 amp. After 40 minutes, the current has started to decrease. The upper voltage is in constant voltage mode at no more than 4.2 V. After 70 minutes, the current, as far as I can see, is below 100 mA. This is the Satatus changes to Stop, which takes a total of 70 minutes and 10 seconds. This is how the charge mode works. At first, it charges Chg first. If it is full, it stops. Let's go see the Discharge mode. The Discharge mode is the highlight mode because it can also measure the battery capacity. I will use the same battery that was fully charged earlier. This mode can use a battery as a power source. Because it's just discharge, we can unplug the charger and throw it away. The first button to switch the mode to DSG mode and then press the second button as usual to start the status. It will change DSG and then let it manage everything by itself. The screen you see is the result of all discharge modes. For example, the current is now 3.98V. If left for a while, the voltage in this mode will continuously decrease. The current will also be released at about 1A and will continue to decrease. On the right, the number above is the battery capacity. It starts to calculate and process the results. The next line will be the watt value. The resistor above will heat up because energy is burned. If you don't want R to get too hot, we have anot
