I just like it because it works great. Gives a constant 5.2v to the ign. I love the LED & the optikill. Most of all I like the reliability because im not a real techno guy. I personally will pay a few bucks for insurance on my planes. Ive had bad luck all my life trying to do stuff cheaper, that eventually causes me a lot more money in the long run.

But thats cool for the guys who have the know-how and can-do, to do stuff like make their own batt backs and voltage regulators.

Can you use more diodes to reduce the voltage more? Id want to drop it to less than .7. That would only really bring the actual voltage of a LiFe battery down to its advertised 6.6v.
