I've been trying to figure out a good one to buy my wife. I have an MTE-15 with the P7 that just kicks butt. It runs off 1 18650 battery. So I assume it's built for the .8 to 4.2 volts
But there are a lot of XPG drop in's that need double the voltage or they only put out "half" or so lumens. For example that Thrunite XPG is listed at nearly 500 lumen but the voltage range is 3.3 to 9V. So does the thing run OK on 1 3.7V cell or does it need 2 or ??? There are a lot of other dropins that say 1 18650 OR 2 CR123A (or whatever those half sized ones are). I was told they will be much dimmer on the single big battery.
I'd like to get the Solarforce XPG 300 lumen dropin they have on sale for $19 but I don't want it to be less than the max with a single cell. Voltage range is "3 to 18V". Does it step up or just output less.
Any information appreciated.....
