BTEC18650LI4PO-2000

18650 LiFePO4 3.2V 2000mAh FLAT TOP

These 18650 LiFePO4 cells have a nominal voltage of 3.2V and a max charge voltage of 3.65V. They are ideal for applications such as small torches, flashlights, modems, cordless telephones, solar lights, temperature gauge and much more. 

Although they share the same physical size as standard 18650 Li-ion cells, they must not be used as replacements for 3.7V Li-ion cells due to their different charging and discharging characteristics.

Specifications:

  • Type: 18600
  • Chemistry: LiFePO4
  • Size approx. Diameter 18.2 x Length 65.2mm
  • Positive Cap: Flat top
  • Nominal voltage: 3.2V
  • Max charge voltage: 3.65V
  • End-of-discharge Voltage: 2V
  • Typical Capacity: 2000 mAh
  • Max Continuous Discharge Current: 5C
  • Max Charge Current: 2C
  • Weight: Approx. 42.4g
  • Protected: UNPROTECTED 

 

Note:These 18650 3.2V LiFePO4 cells are not interchangeable with 18650 3.7V Li-ion cells. They must only be charged with a compatible 3.2V LiFePO4 charger. Using a 3.7V Li-ion charger may damage the cells and pose serious safety risks.

For transportation regulations, batteries are supplied in a low state of charge. Please fully charge them before first use to reach maximum capacity.

 

Usage & Charging

!!!!! IMPORTANT!!!!! These are immensely powerful cells, and extreme care should be taken using them. Only use with branded name, quality chargers and equipment! Unfortunately, we cannot replace batteries that are damaged by non-compliant chargers or equipment. There are so many chargers on the market, we cannot possibly keep track of which ones will work with these batteries. You will have to contact the charger manufacturer to ensure it can charge these batteries without damaging them. Please ensure you only use these (or any other Lithium Ion) batteries with proper Lithium-Ion chargers and equipment. Lithium-Ion batteries can easily be damaged by charging them with too high current or exceeding the maximum rated current discharge. 

Use at your own risk. We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!

  • Do not overcharge! Ensure the charger voltage does not exceed the batteries stated full charge voltage.
  • Do not over-discharge! Ensure the equipment you use do not draw more current than the batteries “Maximum Continuous Discharge Current”.
  • Do not leave batteries discharged for a long period! Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
  • Do not short circuit your batteries! NEVER short circuit a 18650 (or more other) batteries! Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your equipment, and even cause serious injury to you!
  • Do not let your batteries touch each other or other metallic items! Keeping your batteries loose, such as in your pockets, is a serious way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe.

Do not dispose any battery in a fire! There are dangerous chemicals in batteries. If you try to burn your batteries, they will release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling centre.
