A:Lithium polymer battery is also known as lipo battery. 7.4V lithium polymer battery is the same as 7.4V lipo battery.
A: You need to choose the charger in CC/CV charging phase and end the charging at 0.01C current. The battery charger should have 8.4V max charge voltage. The smart charger should also be provided with the connector matched with the 7.4V lipo battery, otherwise the charger can’t connect with the charger.
A: 7.4V means the nominal voltage of the 7.4V lithium polymer battery.Because the nominal voltage of the lithium polymer battery is 3.7V.While 7.4V lithium polymer battery consists of 2 lithium polymer cells in series connection.
A.The lasting time of the 7.4V rechargeable lithium polymer battery depends on the battery capacity and power consumption. If the battery capacity is high and the power consumption is low, then the battery can last very long per charge.
A: The battery swells when the battery is short-circuited, which generates a lot of air that can’t vent out. Stop using the battery immediately and recycle it at the waste centre.
A: For long-term storage, you need to charge the 7.4V Li-Polymer battery at 50%-60% SOC at room temperature, 20°C-25°C. Higher temperatures will cause battery ageing and shorten the cycle life.
A: For a medical-grade 7.4V Li-Polymer battery, basic certifications such as UL, IEC62133, CB, UN38.3 are required. Some other countries will require ISO 13485 quality management for medical devices.
A: Both the 3.7V lithium polymer battery and the 7.4V lithium polymer battery use the same battery chemistry. The only difference is their cells number. 3.7V lithium polymer battery consists of only one lithium polymer battery cell, while the 7.4V lithium polymer battery consists of two lithium polymer battery cells.
A: No. You can’t replace it with a different chemistry. Because different chemistry battery has different voltages and charge modes.
A: The 7.4V lithium ion polymer battery typically has a 500-1000 times cycle life under 0.2C/0.5C charge and discharge rate.For 1C charge and discharge rate,it will shorten the battery cycle life.
