Advantage of using lithium electricity:

• 1. Small volume, light weight, large capacity, environmental protection, no memory effect.
• 2. It is the power supply for portable electronic devices, but the most delicate, lithium-ion batteries in use, please note the following points.
• Use of common-sense lithium electricity:
• 1. You should use a 4.2V Li-ion battery charging standard charger.
• 2. the prohibition of large discharge currents.
• 3. It is forbidden to discharge, single voltage battery should not be less than 2.5V.
• 4. It is strictly forbidden to disassemble, short circuit batteries, probably caused by a short circuit in the fire.

The battery pack is widely used in headlamp, miner’s lamp, flashlight, searchlight, speakers (loudspeakers), wireless surveillance equipment, medical, instrumentation, traffic signs, portable small devices such as 3.7V power supply any utensils.

Note:

• Do not allow reverse charging, the battery should have exactly polarity connection, not vice versa.
• Do not allow short circuit, otherwise it will cause permanent damage.
• Batteries cannot be used under extreme conditions, such as: limit temperature, deep cycle, extreme overcharge and deep discharge.
• Store the battery in a cool, dry place. When a large number of batteries are stored or shipped, the battery must discharge first.
• Do not solder directly to the battery.
• If the battery has noise, high temperature, leakage and other abnormal circumstances, please stop immediately.
• Do not put on fire or try to disassemble, the battery may burn or produce harmful substances.
• Do not allow the old battery or half the battery with the new battery mixed use, otherwise it will produce over-discharge.
• Do not cut the case and remove the battery from the case.
