RE: E-FLITE BLADE CP PRO
I thought I would share this with everyone here, because it isn't as fun sharing it with people who don't know what the heck it is anyways.
I converted a computer PSU to provide the 12v for current battery chargers. It works for both my ICE charger, and the stock e-flite charger.
In the first pic you can see that I added a glass fuse and mounts to make it replaceable without soldering. Alot of power supplies have these already built in. You can also see the wiring to each of the banana jacks. I used all of the wires to transfer the current, although this is probably overkill. Better to be too sure than not sure enough =P.
You can also see in this picture 4 wirewound resistors. You have to put a load on the 5v rail to get the 12v rail up to actually 12v (otherwise it's like 11.5 to 11.8). I used four 1 ohm resistors to give it a load of 1.25 amps, and also to dissipate the heat better. I also zip tied them to the metal and put heat compound to help transfer the heat better.
The next picture shows the operating voltage while charging the e-flite battery with my homebrew battery cable. Next I will have to get a lipo balancer. I am thinking about the equinox by great planes. Any other suggestions?
The last pic shows the power supplies rated voltage and current, although I think that is much more than these banana jacks can accommodate. It does provide nice taps for 3.3v, 5v, and 12v. I have left it running for 2 days straight to see if it would overheat, and it runs just barely warm to the touch (about 90F), even with about 160watts of load on it. You turn it off with the rocker switch, and you know if it is running if the fan is on.
