I agree 2A is the sweet spot.
Only downside, if you don’t want to use 2.5A, would be loosing the 2 clicks to max, no biggie.
Upside is when a xhp35.2 or other new led, that likes a bit more current comes out, one could just swap out the mcpcb and have the extra current with turbo, without having to mod the driver.
If you double click to turbo and then hold the button for just a second it will drop back to the ramp max.
Although for about $5 you can get the parts you need to re-flash the driver and you could then setup the driver with whatever max you wanted. If it was asked I bet Tom could even make a pre-made hex file with a lower turbo output.
You are absolutely right. If I need only one cell for another flashlight, I will always take a different one…
All should be used the same amount of time…
And before using them together again in one light, I will fully top them up all together in the same charger.
All should have the same level of wear especially in a 4S1P light!
And none must have been over discharged, otherwise the danger of a mismatch is high.
If they are no longer perfectly matched, you can still use them together in a 1S4P light (the BLF Q8 for example).
In a 4P configuration, if your have a cell that delivers less power, the others will take over.
Here you just have to ensure, that the others can deliver a higher current in such a case.
(Your have to know the specs of the cells)
But if all 4 cells are always used together in the same light, you most probably needn’t care for all those things…
I almost can’t believe that we’re getting this groundbreaking light for such a reasonable price, as a result of volunteer enthusiasts taking the initiative to create and drive the idea, and partner with a manufacturer to make it happen for so many other enthusiasts. I can’t think of any other hobby I’ve had where this type of community participation happens.
I offer my sincere thanks and appreciation to everyone involved.
