[NSRCA-discussion] Lithium Ion batteries

[DaveL322 at comcast.net]

With my electric plane where I am in the plane every flight to plug / unplug the motor lipos, I use the following configuration:

#1 TP2s1p480 plugs directly into voltage regulator #1 which plugs into battery port on RX.
#2 TP2s1p480 plugs directly into voltage regulator #2 which plugs into an usused channel on the RX.

No switches.  RX power is on/off when I plug the 480 lipos into the voltage regulators.

3 oz total weight.  I use between 40 and 60 mah, depending on length of flight.  I remove the 480 lipos for charging, and charge them individually.  The 480s are taped together, and held into the plane with a single velcro loop.  Very simple, light, and easy.

Regards,

Dave Lockhart

Ed,

How you charge when you use the two batteries with one or two switches configurations?

Robert:
You will get a lighter installation from LiPo's vs LiIon's.  I've heard that the LiIons stand up better to abuse if problems develop made during charging, but I believe that you are still supposed to observe the same precautions with either one.  Given that, I did switch to TP LiPo's when I built my Prestige's and they have worked out extremely well.  If you go with LiPo's, you can then afford (weight-wise) to do a simple, but very effective dual redundant battery setup.  I use a pair od 730 mAh packs and can go all day on that.  Check out the Tech-Tip at http://www.tech-aero.net to see how it's done.  It's even easier than pictured in those diagrams now that there is a dual failsafe switch and regulatior available in one package that operates off of just one switch.

Let me know if you have any questions, but a pair of LiPo's and a PLR5-DR is the lightest and most reliable way possible to use LiPo's.

Dan, I am not planning on running electric, so I would like to know, do I go Litihium Ion, or Li-Poly.  My guess is Li-Ion because of the make up of the cell.  Not a big fan of Dura-flames, So I am intrerested in something different.   I have heard some good things about your batteries, and I would like to hear more.

Thanks,

Robert

If you want more info about the fromeco battery and regulator, drop me a line.  I am a rep for them and will answer any questions that you may have.  I can also get you a great price on a set up.

 Run them with a 6v regulator. They will let you fly all day on 1 charge. Mike

Hey Guys, I am thiking about running lithium-ions batteries this year.  Besides duralite, is there anything else worth using.

Thanks in advance.
