Can the 18650 battery protection board be removed?

The maintenance board cannot be removed, which is not safe for the battery itself. In addition, the mold force is generally discharged by a large current, and the use and design of this kind of electrical materials are different from ordinary lithium-ion batteries. 18650 (the laptop type) is not usable. If you remove the maintenance board and force it to discharge at a high current, after a few dozen times of charging and discharging, the capacity of the battery will decline sharply until it is unusable. 18650 lithium ion battery, with battery maintenance 2113 board and without warranty are as follows: 52611, the height of the battery without board is 410265mm, and the board with added board is 69-71mm. 2. Put 1653 power to 2.0v, if the battery reaches 2.4v, it will not discharge, indicating that there is a maintenance board. 3. Touch the positive and negative levels. If there is no response from the battery after 10 seconds, it means there is a maintenance board. If the battery is hot, there is no maintenance board. Note: The third test is not a professional, you must not do this test, because it may cause a powerful blast, resulting in irreparable personal damage, especially when encountering those defective batteries. It can be removed, but it is not recommended to remove the type 1 power lithium battery without warranty. Because the power lithium battery discharge rate of the model is too high, maintenance can not stand, but it is not recommended to use 18650 batteries as model power lithium batteries, because 18650 is made of steel. Shell batteries are too heavy, and the consequences of blasting after over-discharge are serious. Generally, lithium polymer batteries are used, which are square-shaped plastic batteries. It is best to use high-rate lithium-ion batteries.
