i use those EC-90 6v/12v batteries to run my D8 and my minime at the same time. ive seen that you can use the 12v side to power the JB3 but i need that for the minime's power...so im wondering is there any way to use the 6v side to power the JB3?

6V is bumping right up against the maximum allowable DC input for a JB3, 5V is much safer.

You should be able to run both the Mini Me and JB3 from the 12v side of the Eco Charge.

I'm pretty sure the JB3 shuts down around 5.6v so there's no safety issue...it just don't work!

ok, still one more question on powering the JB3 using the car adapter. Hoping someone can help me out here.

I'm using 2 r/c 9.6v batteries. One for the UA-5 and the other of course for the JB3.  The UA-5 power cable is fine, works great.

In regards to the car adapter plug for the JB3. I did some tests earlier today, just putting the wires on the actual lighter plug and it powers the JB3 just fine when the plug regulator is set to 4.5v. 

Here's my question: Do you actually take apart the lighter plug and solder the battery wires inside and then put it back together? Just wondering how to finish up this cable to make it durable in the field.

Thanks for all the help so far.

would there be any interest from jb3 users for a regulated 5v power source?  input can be 12v or 9.6v battery source.

i could make a power supply so the voltage will be regulated at 5v regardless of the input voltage.

If it's saving me from doing the work and the price is right, I'd be interested.

id be interested too marc, for a 9.6v>4.5 or 5 volts ;D

im so sick of having this huge 12v 12amp battery for festies, its overkill most of the time :P

now if i could only power the jb3 w/ light rc batts, get a few huge amp rating ones and go w/ it, heck, 2 big rc batts arent as heavy as 1 big 12v :P

you can use 9.6v with your car adaptor... the input voltage doesn't change the ouput voltage you set as long as the input voltage is more than what you are converting to.
