I like to leave the main leads of each pack seperate for parallel charging so I simply solder extensions on the aft pack. Then I plug in a balance extension cable and connect the packs with 4" wide clear heat shrink.

I think what he is asking is how to connect them. Basically what you have is two 6S lipos in serries This is what I made up to run my 3S lipos in serries for my Protos. All of my 6s lipos use EC5 connectors and my 3s use deans so you can why the male ends are deans and the female and is EC5 to the ESC.

All of you making up stick pack please pay attention to the total wire length associated with the pack PLUS the wires off your ESC. The longer that total wire length, the harder it is on the caps and the more you may need to consider adding additional caps.

Dr. Ben...should the packs be facing then??? The wires coming out the center of the frame vs. the front?

Here's very poor photo of the way I typical do it. Total wire run length is approx 16" not including the leads from the ESC. Total number of interconnects is 3. Connectors are 5.5mm bullets.

Ripple is the issue. As I underatand it, excessive wire length distorts the pulses emitted by the esc which makes it less efficient. You want lower ripple. Longer wires increases ripple.

Dr Ben, am I close?

Ripple is the enemy. We make all efforts to minimize it with short wire runs on the ESC input side and with battery packs of adequate quality.

It would depend on the helicopter and ESC location. That might work on some setups but you'd have to leave the packs seperate. IMO, it's nice to have all wires on one end for pack loading/unloading.

With a given length of wire, do 65c lipos have less ripple than 30c lipos?

Justin,

For two sets of packs that are otherwise identical except for C rating, I would predict that the higher C packs would have lower ripple under instances of heavy load. The harder the packs are pushed, the more a bone fide higher C rating matters in minimizing ripple.

Here's how mine are wired up for my 700E.

For flight, front lipo positive goes to esc positive, rear lipo negative goes to esc negative, front lipo negative goes directly to rear lipo positive. When in transit I plug the two lipos together to better manage the wires and to minimize the risk of short.

I wire mine up like so.. One solid stick with the series connector
at the end. And extend the bal leads from the rear pack.

I usually only extend one wire from the rear pack. Then I put a connection in the middle of the front pack for the - of the rear pack and the + of the front pack to connect. Then I am left with the + from the rear pack and - from front pack for my 12s leads

Another thing I try not to do is put the cut in heat shrink right where the packs connect, the head shrink seems to split starting right at that hole.
