LG Chem 18650 HE2



in stock


The 2013 LG HE2 18650 battery is still a popular choice among modders because of a high discharge rating of 20 amps and economical price. It is a tried and tested battery that can support the wear and tear from vaporizers and e-cigarettes well and is found in vape shops across the world.

This is the same cell that Efest uses for their re-wrapped 35A purple battery. Note: This battery is only rated at 20A, and can probably only sustain 35A in 1 second pulses (like the 25R), but doing so will decrease the cell's cycle life.
