Attention:
Batteries have a lifespan, and the installed battery should ensure its appearance is intact and free from damage. The voltage should be between 3.2V-4.2. The internal resistance of the battery will increase over time, and excessive internal resistance will affect the normal boosting of the motherboard and the current limiting of high-power output loads. Remember not to use old/damaged batteries or batteries with poor virtual capacity.
This product is a semi-finished product that is prone to damage, so it is prohibited to drop it. The positive and negative electrodes of the battery should be kept in check before being placed. Using a flat 18650 battery can cause the motherboard to burn out and even cause explosions if placed incorrectly. It is important to have a certain understanding of the DIY battery box product when purchasing this product. If you are not familiar with it, please purchase it with caution and consult customer service before purchasing!!!!!!!!
