General Safety
• Use the battery within the specified temperature range.
• Do not disassemble, modify, or damage the battery to prevent leakage, overheating, or fire.
• Keep the positive and negative battery terminals from touching each other or metal objects.
• Avoid welding or grinding near batteries to prevent fire from sparks or arcs.
• Do not drop metal tools onto the battery to prevent sparks or short circuits.
• Lithium-ion batteries pose fire risks, so be aware of these hazards:
a. Thermal runaway can release flammable and harmful gases such as CO and HF.
Vapors from burning batteries may irritate the eyes, skin, and throat.
b. The concentration of these gases could lead to deflagration and explosion.
c. The battery electrolyte is flammable, toxic, and volatile.
• If a battery leaks chemicals or emits odors, don't approach it - contact professionals for
safe disposal. They'll need proper protective gear.
• Do not touch a battery that's been submerged in water, to avoid electric shocks. Discard
soaked batteries through proper recycling channels.

• When the SoC drops to 1% without any power input, power off the unit promptly to
prevent overdischarge.
• Before storing, charge it to 60%-80% SoC and fully cycle every 6 months to maintain
battery health.
• For long-term storage over 6 months, charge it to 40%-60% SoC and fully cycle every 3
months.
• Safe storage temperature: -20°C to 40°C (-4°F to 104°F). For storage over a month, aim
for a range of -20°C to 25°C (-4°F to 77°F). Perform a cycle charge before reuse.
• Avoid extended storage periods as it can impact the battery's performance and lifespan.
• Use a dry and soft towel to clean the battery's exterior.
