LG HG2 18650 (3000MAH,20A)
While the original release of the LG HG2 was in 2014, production has become available in Summer 2015. A 20 amp, 3000 mAh milestone is, in some way a holy grail of stats. A battery that can both be high-drain, and high-capacity is just what everyone wants. The LG HG2 can be seen as a 500mAh capacity upgrade from its predecessors the HE2/HE4 which also have a 20A discharge limit.
LG Chem is on a rolling schedule of releases and research, all planned years in advance. An average of between 6% and 10% increase in battery performance is expected, compounding yearly. That means, taking into account the battery specs and LG Chem's release schedule, the LG HG2 will likely be a good contender for one of the best 18650 batteries for some months to come for high-drain applications.
