I'm working on a 2 stage RS (2190's + 2850's) on 3s, with a 2850(honey badger) as the pusher. I will be using a rocker switch to switch between full rof (14dps), and dropped rof (8-9dps). By my calculations, I need to to drop the voltage by 2-2.5v. The only info I could find was to use 1N5400 3A diodes that drop the voltage 0.7V each (so that I would need to use 3 in series).
Now my question is; are 3A diodes going to be safe to use with my particular setup? (I estimate my motors at full stall to be in the neighborhood of 75A). If not, what would be a better diode to serve my application? Perhaps there is something else I should be using.
Any help, suggestions or clarification would be much appreciated as my knowledge of circuitry is quite basic.
