Which brand of 18650 lithium battery charger is better?

Source: 2020 - 03 - 25 clicks: young man, which brand 18650 lithium battery charger is better? Samsung, panasonic and other imported products better, but more expensive. Domestic battery capacity and relatively poor life. 18650 is the ancestor of lithium ion batteries. Lithium ion battery is SONY of Japan to save money and design a standard lithium-ion battery. 18 said to 18 mm in diameter, 65 said length is 65 mm, 0 means cylindrical batteries. Ordinary 18650 cells divided into lithium ion battery, lithium iron phosphate batteries. Lithium ion battery voltage is 3. 6 v and 4. 2 v, lithium iron phosphate battery voltage of 3. 2 v, the capacity is 1200 mah - commonly 3000 mah, the general capacity of 2200 mah 3600mAh。 2, 18650 battery charger for lithium battery production is by far the most commonly used batteries, not only high energy density, and light weight, widely used in mobile phones, laptops and a flashlight, etc. , almost every household will have a lot of lithium-ion batteries, some even have a lot of 18650 lithium batteries. But, in addition to mobile phone and laptop batteries, lithium ion batteries and other 18650 lithium-ion batteries, especially need a special door charger to charge. Assume that home with much, as long as a few pieces of the battery, then buy a dedicated charger isn't worth a few, my name is yan chai the charging thread below, you can directly through phone charger for all kinds of lithium battery. The first step, find a suitable to the size of the disposable lighters to open, it is best to run out. The 4056 lithium battery module size shall prevail. This is used to make the shell, this is more beautiful, can maintain the internal circuit is the second step is to transform the shell of charging line, directly cut off the husk of disposable lighters, you can use the heating blade, very easy to do. Of course, you can use a saw, but be careful. The third step is to grinding and cutting the shell, and then according to the size and shape of the shell cover with a piece of transparent plastic, open the hole in the fourth step: make a plug. What I use is 5. 2 mm plug. I also can according to their own need to change a different plug or two alligator clip. But, please pay attention to the positive and negative electrode can't short circuit. Step 5: welding the charging module. I use a mini - Usb 4056 modules, but also has a miro - Usb, depends on how you use the usb cable, this is the most mobile phone use. Will note the charging plug welding, stick on the positive and negative step 6: after the shell side to open the air inlet, the blade was heated. After open the hole, you can use the file according to the USB port for thinning shape, it will be more beautiful, then load module. It need a little patience step 7: the self-made copper cover adhesive glue. This is done, the next step is to stop testing. Step 8: test. Connect mobile phone charger, then connect the lithium battery charge on the other side of the plug, assuming that green or blue light said it was charging, suppose the red light said charging is complete, you can pull the plug more than 18650 lithium-ion batteries, we introduce the content of the comprehensive evaluation of the two plates production process and method of knowledge, we can understand the customers to buy the product you are interested, we can practice analysis, separation and interested in hand made friends, you can refer to the above information, such as the content of the comprehensive and detailed research to suspend. Of course, due to the specification requirements is very high, the best reference for professional advocacy analysis, in order to avoid unnecessary loss.
