803035 3.7V 800mAh Lipo Battery Power Bank with KC CB Certification. This small size mini Lithium Polymer Battery offers reliable power in a compact form factor.

Q: Can I use Lithium batteries mixing with other battery types?

A: If different types of batteries are used together, or new batteries are used with old ones, the difference in characteristics of voltage, capacity, etc. may cause over-discharge of the battery which is exhausted first, leading to swelling, bursting or fire.

Q: What will happen if the batteries with different capacity are packed together?

A: If the batteries with different capacity or new and old batteries are used together, leakage, zero voltage and so on might happen. If the batteries are rechargeable and are being charged, some batteries are overcharged and other batteries is not in full charged state. During the discharge, some batteries cannot discharge fully and other batteries might over discharge. This way, the battery will be damaged.

Q: What are the possible reasons for zero voltage or low voltage of the battery pack?

A: Short circuit or open circuit of the connector or wrong connection, de-soldering or cold solder joint between the batteries and lead, wrong connection between the batteries.

Q: What are the possible reasons if the rechargeable battery or rechargeable battery pack cannot be charged?

A: The battery is zero voltage or there is battery with zero voltage in the battery pack. There is wrong connection inside the battery pack. There is abnormally of electronic components and/or PCB inside the battery pack. There is failure in charger. Outer element causes the charging efficiency to be too low, such as extremely low or high temperature.

• Higher energy density: Lithium polymer batteries have a higher energy density than lithium ion batteries, meaning they can hold more charge in a smaller package.
• Faster charging: Lithium polymer battery packs can be charged faster than lithium ion batteries. They also have a longer shelf life and do not require as much maintenance.
• More stable charging: Lithium polymer batteries are more stable during charging than lithium ion batteries. They do not experience the same level of voltage fluctuations or charge peaks.
• Lighter weight: Lithium polymer batteries are generally lighter weight than lithium ion batteries, making them more suitable for power-intensive devices.
