Not suitable for dismantling.

It is impossible to remove the maintenance board, as it is not safe for the use of the battery itself 

Individual batteries require high current discharge, which differs from individual lithium batteries in terms of application and design Individual 18650 (the kind on laptops) are not usable. If you remove the maintenance board and force it to discharge with high current, the battery capacity will rapidly decay after ten cycles of charging and discharging, until it becomes unusable 

18650 lithium battery, with battery maintenance 2113 board and without protection are as follows:

1. The height of the battery without a board is 410265mm, while the one with a board is 69-71mm. 

2. Discharge 1653 electricity to 2.0V. If the battery does not discharge when it reaches 2.4V, it indicates the presence of a maintenance board. 

3. If there is no response from the battery after 10 consecutive seconds, it indicates the presence of a maintenance board. If the battery becomes hot, it means the maintenance board is not in use. 

Attention: The third point of the exam is not about personnel. Do not conduct experiments like this, as it may cause a powerful explosion, resulting in irreversible personal injury, especially when encountering damaged batteries. 

It may be dismantled, but with dismantling

Type 1 energy batteries are all unprotected because the discharge rate of the model's energy batteries is too high and maintenance is unbearable

However, it is not recommended to use 18650 batteries as model energy batteries because 18650 is a steel shell battery with a large weight, and once it is over discharged, the explosion result will be significant. Some use lithium polymer batteries, which are block shaped plastic sealed batteries, and choose high-speed lithium batteries
