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-4.2V. 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 installation. Using a flat 18650 battery incorrectly can cause the motherboard to burn out and even cause explosions. It is important to have a certain understanding of DIY battery box products when purchasing this item. If you are not familiar with it, please purchase with caution and consult customer service before purchasing.
