LG batteries are made in China by the Shenzhen Bestly Technology Company, which is indeed based in Shenzhen, the city north of Hong Kong which is home to a huge number of vaping equipment makers. Established in 2014, LG is best known for its lithium-ion 18650 rechargeable batteries. These are used to power mechanical mods and variable wattage box mods which can achieve high power outputs, up to 200 watts in some cases. One good example of the high-tech batteries they offer is the HE4, an 18650 originally developed for power tools, so it’s a battery with plenty of power. The cell has a rating capacity of 2500mAh, which means that even the heaviest vaper will get plenty of use between charges.
