For mobile power we have a certain understanding, there are many friends will be curious mobile power is composed of those parts, the following we have to look at:
Mobile power is mainly composed of three parts.
1, shell This can be based on batteries, PCBA protection board to choose the mold, DIY, you can use the mold can be. This eliminates the need for matching jobs.
     2, batteries, batteries in the choice we can choose 18650 or polymer, 18650 batteries are fixed size. So only in the mold can choose the corresponding mold, if a little industry resources, we can directly take the mold on the market to install. Polymer batteries are free form, but after the factory from the battery factory, but also a fixed length and width, unless you design your own private mode, and then let the batteries in accordance with your regulations to produce batteries.
3, PCBA protection board, his role is to play a boost, buck, constant current constant pressure such a role, so we in the selection of time, pay attention to see the quality of PCBA board. As well as his electronic parameter values. How to argue is a good board, we can use a professional instrument to test.
Mobile power is basically the three main raw materials, and then assembled, is a complete mobile power, of course, we have to do some tests, such as the platform voltage, discharge voltage and current, which is the test thing, do not tell.
