+# What's the maximum current a pyro channel can handle?
+
+Older Altus Metrum products used Vishay Si7232DN FETs as switches.  They are 
+rated for 25A continuous, 40A pulsed.  Newer products use Taiwan Semiconductor
+TSM200N03D FETs which are rated for 20A continuous, 80A pulsed.  In pyro use, 
+we're closer to the pulsed rating than continuous.  However...
+
+Please note that Ohms law applies.  Whatever your battery voltage is and
+whatever your e-match or other device's resistance are will limit the
+actual deliverable current.  With a single-cell LiPo battery, the fully
+charged voltage is 4.2 volts, and a feature of LiPo batteries is that
+they have very low source resistance, so we can mostly ignore it.  A
+typical e-match has 1.0-1.7 ohms depending on the wire length.  The FET
+on resistance is less than 20 milliOhms, so we can basically ignore
+that, too.  Only the resistance through wiring and the match matters.
+So, by Ohms law, E = IR, I = E/R or 4.2/1, meaning the most current you
+can deliver to the pyro element is 4.2 A.
+
+A typical commercial e-match fires in about 13 microseconds under these
+conditions, which is why we think 50 milliseconds is .. a very long time!
+
+You'd think moving to a 9V alkaline would allow you to deliver 9A, but
+it doesn't really work that way.  Unlike LiPo batteries, Alkaline cells
+have a very high source resistance and their current producing ability
+is nowhere near linear. 
+
+If you're using a programmable pyro channel on Altus Metrum products that 
+include that capability (TeleMega, EasyMega, EasyTimer) to do something like 
+turn on other electronics, there is an additional consideration.  The screw 
+terminal strips we use can handle large peak currents, but are only rated 
+for a maximum of 6A continuous current per screw.  This means the best plan 
+if you need to switch something power hungry is to include a high-current 
+FET switch in your electronics, and use our FET to switch just enough current 
+to control it.
