If I get a Fenix PD32 light, how would it perform on the AW 18650P cells, that are 2200 mAh? The site I saw sells them for $12.99 each. They also have the Pila IBC 2 cell charger for $46.99 Is there an 18650 battery that would be better for the light, assuming the 2200 mAh cell fits? I am wondering if the protected 2200 mAh cell would generally perform better than 2 regular CR123A batteries. Also, is there a smart charger that is good but less expensive than the Pila IBC? I am assuming you want a charger that does not over-charge the 18650 cells (intelligent). Thanks.
