Witty Fox 3.7V 7000mAh Li-Ion Battery

This is 3.7 volt lithium ion battery of 7000 mAh, the Li-ion battery is one of the most modern battery technologies available. Lithium ions are the primary element in its electrochemistry. Lithium can easily pass through a micro-permeable separator because of its extremely small size (third in size only to hydrogen and helium). Lithium ion batteries are therefore capable of having a very high voltage as well as high charge storage per unit of mass and volume. This is compatible with TP4056 Lithium Battery Charging Board

This 3.7 volt 7000 mah lithium ion rechargeable batteries are widely used in GPS , DVD, Tablet PC, Development boards like arduino , BBC micro:bit , MP4 Player, Power Bank, Mobile Backup Power Supply, Electric toys , Bluetooth Speaker, IOT and Industrial applications.

This 3.7V 7000 mAh Li-ion battery is from the brand Witty fox which is invented by TIF Labs.

1. Which battery is better lithium-polymer or li-Ion?

  • Li-ion batteries have a very high-power density, which means they can simply pack more power cells than lithium-polymer batteries. Smartphone makers use this attribute to pack more power while still maintaining a sleek design profile. These batteries also lack a memory effect

2. Should you store the Li-ion battery with a full charge?

  • The Lithium-Ion batteries must be stored at 30-50% maximum charge for the best results. It is better to store them when they are fully charged when you're not going to recharge in a few months.

3. How can I improve my lithium-ion battery life?

  • Below are some of the ways to improve Li-Ion:
  • Use partial-discharge cycles.
  • Avoid charging to 100% capacity.
  • Select the correct charge termination method.
  • Limit the battery temperature.
  • Avoid high charge and discharge currents.
  • Avoid very deep discharges (below 2 V or 2.5 V)

4. Where can the Witty Fox 3.7V 7000mAh Li-Ion Battery be used?

  • The witty fox 3.7v 7000mah lithium-ion rechargeable batteries are widely used in GPS, DVD, tablet pc, mp4 players, power banks, mobile backup power supply, Bluetooth speakers, IoT, and industrial applications.
