Sorry about all the questions :-p
So the batteries have to be in parallel. Lets say I have a battery box with 4x Keeppower 3,7V 3500mAh
So what I get is 3,7V and 14000mAh. I'm not sure if I understand it right. Does the driver of the flashlight limit the 14000mAh down to what the led's need? - or is the 14000mAh just the amount of "stored power" - meaning that the flashlight will run for 2,85 hour? (14000mAh/4900mA)
Also I'm trying to find a watertight battery holder / battery box for 4-6 batteries in parallel. Any suggestions?
I've found a lot of holders for batteries in series, but none in parallel, and most of them are sold with a headlamp:
Spark SX5 (same battery holder as Spark SDB100 reviewed here)
Solarstorm battery case:
Pannova B-C04
