Note: LG 18650 cells are not authorized or intended to be used as stand-alone, removable, rechargeable power sources for e-cigarette or vaping devices, or to be handled directly by consumers in any manner. Clients who inquire about LG loose cells must intend to manufacture battery packs with proper outer casing, PCM/BMS and protection functions and be able to provide documents to prove this.

The LG HE4 is heralded to be the latest and greatest iteration of the HE series by LG Chem at the time listing this product. The HE2 sits alongside the Samsung 25R as a standard in 18650 batteries in 2015. They are well balanced to provide adequate capacity, and high discharge ratings, as well as being economical on price. 

*At the current time, the HE2 cell is still a popular choice (2018) and was not replaced by the HE4 like predicted. 

The HE4 offers slightly better performance at higher temperatures and also heats up less when undergoing high-current discharges.

In Asia, 18650 batteries are binned by quality into A, B, and lower bins. C-bin batteries are often recycled from battery packs. Lower bin batteries will underperform and may be dangerous.
