thebaronn Posted October 24, 2010 Share Posted October 24, 2010 Hello!I have aquestion about the CMB16D LOR boards.It requires a 12V input to run the board.If I have a ELL hooked up to the board, what is the smallest "battery" pack I could use?It only needs to last 3-4 hours.For the last few years I have been using two 6V lantern batteries. (still using the same ones for the last 3 halloweens)I'm wondering if I could get away with something smaller, any reccomendations?I only need to power the board and the ELL.thank you!

scubado Posted October 24, 2010 Share Posted October 24, 2010 Sounds like you could get away with using an 8 cell AA batery pack. there only about $2 at Radio Shack. Link to comment Share on other sites More sharing options...
Guest guest Posted October 24, 2010 Share Posted October 24, 2010 You need 12V to run the DC board electronics, but supply for any devices you control can be 5-60V. Looks like the ELL runs on 9V, 150-200 ma max, so assuming an on-board regulator for the ELL.I'm assuming the devices you are controlling with the DC board are running on less than 12V and thats why you need the separate 12V for ELL and controller?

scubado Posted October 25, 2010 Share Posted October 25, 2010 You could still use the 8 cell AA battery pack. you can solder in a wire in the series of batteries to tap at the 6v or 9v spot to power what you need. Link to comment Share on other sites More sharing options...

-klb- Posted October 25, 2010 Share Posted October 25, 2010 Correct. The only issue is that battery supplying 6V will get discharged first, because it is supplying current to both the LED lights, and the card, while the second one in the pair is supplying voltage to just the card. But, for a one time use deal like this, it is probably not that big an issue. You could also use a lantern battery as your supply for the LED lights, and the first 6V of the card logic supply, then add 4 more AA, or C cells in series to get the last 6 volts up to 12V.
