QUICK UPDATE ON BATTERY CAPACITY:
In preparation for the long running test, I measured first the fresh capacity of the Orbtronics that I got this week to confirm their capacity. I do that to both label them to choose/bin the best but also as a safety measure ... You don't want to discover that one battery is counter fit or damaged ... And also you can return them if they are way off the stated capacity ... But please don't be too picky - there are many assumptions on any number printed on a label ... I just do it to be sure they are in the ball park.
The good news is that the stated 3500mAh capacity is now confirmed - they had an average of 99.6% of that number. My sample was four batteries, best 99.9% and worst 99.5%.
Before somebody screams that is not 100%, let me state I used a 0.5A discharge cycle ... I am sure they are 100% if I use 0.3A rate which is where I need my endurance in the ~220 lumen mode for all night runs. Also another factor that is even more important is that my charger might be using more conservative voltage limits for the end-discharge and the max-charge ... Cutting a bit short and thus reporting less mAh capacity. In my opinion this are 100% OK.
In summary - Obtronics labeling is 100% truthful ... Which is great. Still batteries are not just defined by the mAh statement as your milage WILL vary if the modes you use are on the higher amperage range / high drain for other reasons. My guess, based on the MEASURED capacity is that my goal of running the main mode of 220+ lumen all night it might be within reach as AT reports runtime for 3400mAh batteries, so I should get few extra minutes to make the combination of the Wizzard XHP50/Warm with Orbtronics 3500 the dream for any mountain ultra-marathoner.
Still the proof should be in the run time. My plan is neither to run it all night, nor run it one hour at 2000 lumens ... As I don't want to push the limits of the light thermal endurance ... Even if reported as legal and self-sensing ...
I just plan to run the 500 lumen mode to see how the runtime number compares with the stated number and extrapolate the over or under rating to the reported 200 lumen number. I am not a reviewer ... I am just a user!
Thanks for the thanks for the mini-report - it was my way of returning the favor of prior reports of the limits of the protection on some batteries - that is the great thing about this forum: we help each other to get the perfect light one step at a time. We also have to be reasonable with any manufacturer and not get catch an ultra-picky number game ... That is how you help them to build better products or update their manuals. Each Manufacturer have pluses and minuses ... Nothing wrong about that if you get into their products fully informed.
