Please Note: Unprotected 18650 cells are not to be used in e-cigarettes devices or vape pens, Li-Ion Cells require safety precautions and mechanisms to make their use safe.

We are not aware of eCigarettes or vape pens that have such safety mechanisms. Misuse of Li-Ion Cells in eCigarettes and vape pens may cause a serious risk to personal property and safety.

What is the difference between LiPo and Li-ion batteries?

The most significant difference between lithium-ion and lithium-polymer batteries is the chemical electrolyte between their positive and negative electrodes.

Lithium-ion batteries: They have high energy density and cost less than lithium polymer. … However, their cost is high (30% on average) as compared to lithium-ion.

How do LiPo batteries work?

The LVC detects the voltage of the battery and divides that voltage by the cell count of the battery. So it would see a fully charged 2S LiPo as 8.4V, or 4.2V per cell. … The LVC works to cut off the motor of the vehicle (or in some cases, pulse the motor) to alert you to a nearly-depleted battery pack.

What is the advantage of LiPo batteries?

LiPo batteries may also power the next generation of electric vehicles. The main advantages of LiPo battery cells are that they have about four times the energy of density of nickel-cadmium or nickel-metal hydride batteries. LiPo batteries are very lightweight and pliable and can be made in almost any size or shape.


  • High energy density – potential for yet higher capacities.
  • Does not need prolonged priming when new. One regular charge is all that’s needed.
  • Relatively low self-discharge – self-discharge is less than half that of nickel-based batteries.
  • Low Maintenance – no periodic discharge is needed; there is no memory.
  • Speciality cells can provide a very high current to applications such as power tools.
