The main problem with long leads is excessive voltage drop due to higher resistance if the wire gauge is too light. Just use 22AWG and also avoid any tin plated connectors and you should be fine. Braided wire can be helpful, but isn’t really necessary most of the time. </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt;

The Jaccio works really well. I also make regulators that are adjustable and fill a niche if you have a need for redundant batteries and want some additional flexibility in the setup. Either solution can work. And you are correct that a 480 mAh pack isn’t a lot of capacity, however with a good LiPo, there ability to deliver current on demand is more than adequate. Capacity for some number of flights is the bigger question. </SPAN></FONT></div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial"></SPAN></FONT> </div> <div class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE:
