First, looking for some clarification...
The 2x18500 setup has greater wattage output overall... right?
Are 18500 cells (generally) as severely over-rated as the smaller 16340?
Is anyone using a 2x18500 arrangement to power an MCE or P7? How do you like that setup compared to a single 18650?
I'm happy in 18650 land... but I am curious.
