My two 21700 48G came in yesterday from FT after an unusual 5 weeks transit - but they made it nonetheless.
Quite some fat and heavy cells - essentially big 18650.
Now where is that mysterious X light? :smiling_imp:
A 21700 48G is only about 1mm longer than a protected 18650 cell. Many chargers accommodate this length no problem, including my Lii-500 and MiBoxer C4-12.
