Does anyone know the mA usage on the following, or how to find it...

12 Revy?
Warp Feed?
E-Mag?

Well I assume you're talking about mA as in milliamperes (electric current).. To find the current draw of each device, go to radio shack and pick up a nice multimeter (bout $20 bucks, but well worth the investment).. Then attach it in between the positive lead of your power source (battery) and the corresponding lead of whatever you're measuring. Be sure the multimeter is measuring current, and that the test probes on the multimeter are in the correct ports to measure current (as opposed to measuring voltage or resistance).

One thing though, the current draw will vary according to the conditions of the equipment. With our without a load on the motor (having paint in the hopper, or paint in the warp..), temperature of the device (also I believe I remember Tom saying that when the E-mag solenoid gets heated from continual usage, it can even draw an amp [1000mA] of current!), and even how many cousins you have(well not really) but if you're making some current based device you shouldn't make your component tolerances too tight.

That's the basic way to do it.. what do you need the info for?

Sorry, yes I was talking about miliamp draw, & thanks for the info. I was hoping the numbers were out there somewhere but this works too.....

I curious about the mA draw on the E-Mag, if it's capable of 1000mA draw, why is the battery rated at 650mAH? I'm probably missing something here, I don't know much on the subject.

mah is the term given to the "life" of the charge at a specified Load or draw off the pack. For example, if you race R/C cars, your packs are rated in mah at 25a draw from a typical 12turn motor at full open. When i build packs of that nature, my mah is a bit lower because i rate my opacks at a 30a draw.

My new pack for my emag is using a 1600mah pack at 18v. My secret, but they are a bit expensive, and last estimated 50,000 shots with warp and revvie.

Psychomag, i'm interested in your battery pack, post pics if you can.

I'm trying to figure mAH for batteries ran in a series. Just for example, 9v batteries are rated at 500 mA, if you wire the two in a series, I know the voltage doubles, but, does the miliamps stay the same at 500mA or does it double to 1000mA?

Ma's stay at the amount of one battery when the batteries are wired in series.
