Just a little input from me here, I've owned my MVP 2 (b?) for almost 3 months now.
I never really let the battery go below 3.7, but I've noticed that my fire button LED will not change color
no matter what the voltage left on the battery is. It could be 3.4,
it could be 3.6, or it could be 4.1 it always stays green.
Not really a big deal for me but was just curious why this would happen!
The manual says that green is 3.75 and above, yellow is 3.61-3.75 and red is below 3.61
if you never let it go below 3.7v, it should stay green
I musta missed something... ?
think about, the whole process happens - 3.6v to 4.2v (.6v)
