The big size 46800 and 46950 Li-ion batteries seem to have found their niche in some new powerful lights and lanterns. Some flashlight lovers think bigger batteries are definitely a plus. They have advantages in capacity, no multi-cell voltage issues. And charging one battery is much easier and safer than 3S or even 3P cells.
While, as for charging efficiency, it may take most the day to get a big 46800 or 46950 fully charged via the charging port on the light. But you can charge three or four 21700 with 2A at once more quickly. Besides, to compare the energy density among those Li-ion batteries, the 21700 battery seems still the optimal choice.
Do you think the trend towards big batteries is the future? And some users told they are also interested in external charger for these big batteries. Will it only cater to a smaller, niche market. How about your view on this? ;-)
