Fat Batt

Works as advertised - be aware, it is bigger than 1st Gen(?) 21700's. I have to force it into my nitecore I bought back in my 16850 days...it's slightly fatter and longer. Ordered an Xtar 4 slot(on site) charger with a second 21700.

I love these batteries and they work flawlessly in my Nunchaku 2, but they are too large for an Innokin Plexar.
GOOD POWER
