Few questions.......... Question though. It takes an 18650 battery, which I thought was 3.7v
However the unit is VV up to 6.0V.
How is that possible with the battery being 3.7V? Am I missing something? ........
I'm no expert, and have no idea how it's done. However, I do know that many electrical devices use capacitors of one kind or another (there are many) to temporarily drastically increase voltage. From 110 to 50000 volts in the old CRT televisions. Your outside AC compressor does the same thing. Even some fan motors require more voltage to get the fan blade turning initially, then much less to keep it going. That's why many fan switches have the highest setting when you first turn them on, and then go to medium, low. if they started out on low, they'd need more help, which would necessitate higher manufacturing costs.
From wiki on capacitors: ....... "even a seemingly innocuous device such as a disposable camera flash unit powered by a 1.5 volt AA battery contains a capacitor which may be charged to over 300 volts".......
I've seen this same question asked several times. You'd think someone on the forum would know how APV's do this.
