Safety Precautions:

Li-ion and Li-po batteries are highly volatile. If not charged or used properly, they can cause fires, personal injury, or property damage.

• Do not reverse the polarity when charging or discharging the battery.
• Avoid using low-quality chargers or charging panels to recharge the battery.
• Do not mix used old batteries with new ones, and try to avoid using different brands of batteries together.
• When purchasing a Lithium battery, always make sure that the battery specifications are compatible with the expansion board. Choose batteries from the official manufacturer, and ensure the stable and safe operation of the batteries by conducting aging tests.
• Lithium batteries have limited cycle life and degrade over time. When batteries reach their maximum service life or have been in use for more than two years (whichever occurs first), they should be replaced.
• Handle batteries with care and store them away from flammable and explosive materials. Keep them out of the reach of children to prevent safety accidents caused by careless storage.
• DO NOT INSERT non-rechargeable batteries (such as dry cells) into the battery holder. Attempting to charge a non-rechargeable battery can result in serious consequences, including explosions.
