The "low end" pack in a 10S setup is the one with the neg (black)
main power lead going to the ESC input. This is the pack that you
would consider as "channel 1" on the Cellpro or TP chargers.<br>
<br>
The goal is to power the radio from the motor pack to that voltage
regulator needs to be higher than the regulator used on the back up
pack which can be a 200-350mah 2S pack. Jim O. came to me with this
setup a while back and as he said has been flying it for some time
with success. I am working on a schematic or picture to go on the
web site to show the proper hook up of the system.<br>

I would like to emphasize that the pigtail from Chris Moon could
physically be plugged into either of the 5s balance connectors
which Jim identifies as the "bottom" connector. If your esc is not
fully optically isolated on the ground leg and you plug into the
"upper" battery, there will be smoke. If there is a BEC in your
ESC, there will NOT be isolation. In that case, I suggest that you
tag or use nail polish to identify the correct balance connector
on each pack as you will be plugging into this balance connector
whenever you change batteries. It is also a good idea to use a
switch for each power lag and check each leg for power separately
as part of your pre-flight process. It is easy to forget plugging
in the balance connector when you start using this system plus it
is important to confirm that both legs are working before each and
every flight. Otherwise you can lose your redundancy before the
flight even begins.<br>
The Castle HV series without BEC allows you to use either balance
connector without any issues.<br>

working great. I have my two cell LiPo charged to 7.5 volts and
it is connected to a 6.0 volt regulator into the receiver. The
cable connected to the balance connector on the "bottom" 5S is
connected to a 6.3 volt regulator so it supplies all the current
to the system and the 2S pack never needs charging. I'm using
an 800 mAh pack but it could be even smaller.

<blockquote type="cite">Guys,<br>
Chris Moon just e-mailed me about some leads that
were done at the factory. These leads run off your
balance leads to a voltage regulator and allow your main
battery pack to be utilized as a redundant receiver
battery. It is NOT meant to be a primary but it will
save 20+ grams if you're running 2 rx batteries. You
still have to run the 2nd regulator for true redundancy
but you eliminate the 2nd battery. These leads are
factory made and eliminate the need to make them
yourself with the concern about plugging in to the wrong
cell. I know in my article, I was pretty much against
doing this as a backup but, with Chris having this made
at the factory, he has all but eliminated making a
mistake by tying to the wrong cell. I have the link
that I'll e-mail you off-list or you can just go to his
website. I don't want to break the NSRCA list rules by
advertising for him even though he advertises with the
NSRCA. The leads are only $3.99 each and are found
under the Connectors/Adapters listing.<br>
