Something else that has bothered me a bit.. The VL loader says it's a 12V
hopper, except that it uses two 9V batteries. So I thought, well, maybe they're using two batteries in parallel to give it the current or the battery life it needs. But that's still only 9V. But no.. these batteries are in series making 18V. Hmm, I think to myself.. Why would they burn off 6 volts just to make the thing run at 12V? Why not make the thing work off 9V or 18V.? Is this just a bunch of propaganda? I suppose I could open the thing up and measure the voltage to the motor and if that's 12V, then I guess it kinda makes sense but who advertises their product as 12V when it's actually 9V input 18V input? -Bruce "Bruce Chang" <bechang@swspambegonebell.net> wrote in message news:3t7Sc.1420$%p3.1309@newssvr22.news.prodigy.co m... > So I'm more or less a newbie at paintball.

Regulating the voltage down to 12 volts means that you lose power due to heat dissipation. On the assumption that the motor draws .5 amps, you're losing 3 watts of power when it's on. It wouldn't really save battery life because power is being wasted to heat. But I suppose since there's no standard 12V battery, this was the easiest way. |

A regulator that drops 6 volts just disappates it to heat whereas the power going into a transformer is the same coming out. The previous poster is under the impression that regulating the voltage down *saves* battery life. I'm not convinced that regulating voltage to 12V saves battery life. I would imagine it was just cheaper to do that with the availability and plethora of 12V motors and 9V batteries. |

Except to note that there is a doohickey that does it. ![]() For my part, I always just assumed that it was 12volts instead of 18 because 18 would just churn the motor too quickly to allow effective paint feeding, so they stepped it back down. -- Jeff Goslin - MCSD - www.goslin.info It's not a god complex when you're always right |

You weren't supposed to take that joke so literally ![]() And for the record- yes, it's quite possible that an electrical engineer(ing major) wrote this code. Because it actually performs a function ![]() |
