any merit in running dual battery packs ?

[Dean Pappas]

Hello Urs,
The Jaccio regulator is a great item, but I am concerned about running with more than 3 volts of headroom: this increases the power dissipation.
It may simply require a heat sink be added to the regulator component. That is usually just a tin or brass fin soldered to the big tab on the IC.
Jim? Whadda you think?

Hi Jim,
 
Many thanks. I have the Jaccio already. I use it in conjunction with a 5 cell Nicad. Can I just connect it to a Li-Ion battery or are there prior readjustments to be made? TIA

Hi Urs,
I like the 18650 cells that are in the 2000 to 2400 mAh range now.  These are the cylindrical cells with metal cans like Central Hobbies sells.  I believe they are more rugged than the Li-Poly cells and one doesn't need to worry about taking them out of the plane to charge.  I use the Jaccio Perfect Switch Harness but I'm biased because I make them.
Regards, Jim
