using a CC BEC for onboard charging system

[12voltfun]

well its still just an idea but here we go. i am working on a chargeing system for my gas powered rig useing a d.c. motor running off the crank on the engine to make volts and using a CC BEC to regulate the volts down to 6 volts to charge my rx battery . like a 1 to 1 rig .
any one have any input

Sounds like it should work to me. Your just turning the DC motor into a alternator really. Guess you will just have to do some testing to see what voltage the motor will be putting out first to see if the BEC can handle it. And you will have to check to see if the motor can handle what the crank is sending to it as well!

It does seem like a lot to do to just have a on board charging system though. A good lipo will solve any short term battery power loss. But maybe your doing it for just the cool factor? What are you trying to put tis on and why?

It will work, but you won't have amperage regulation. A discharged pack could allow for too many amps to pass through. A CCCV regulator is a better idea. I have some that will terminate the charge, if you wanted to use them to charge lipo packs.

thanks guys, i didnt think about over charge, a switching regulator would be a must .
I plan to put on my gas rig im building Project Vitamin "G"
and ya its for the cool factor!!
