Batteries needed for Thunda

Postby jondubinsac » Fri Jan 11, 2019 7:04 am

G'day mates (practicing my Aussie talk),

My name is Jonathan DuBose, live in Sacramento, California, USA and I am coming over to Thunda Down Unda.

It suddenly dawned on me that I might have a battery problem. I will need, at a minimum, qty 1 400mah and Qty 1 900mah LIPO battery to power my Telemetrum and TeleGPS devices.

I am pretty sure I will not be able to ship them and I don't see any on the Australian Rocketry site although I do see BRB batteries. I do see Altus Metrum products on the site and know that they are used in Australia.

If someone can help me out here it would be greatly appreciated.


A little more about myself. First off, I am the proud grandfather of George Rubinstein from Melbourne, Australia's first Tripoli Mentoring Program flyer who will be attending Thunda with me.

I am a member of several clubs in California, a member of AEROPAC which hosts 3 launches at Black Rock each year and am also club newsletter editor.

Welcome Jonathan,
My experience shipping LiPos when traveling is to take them as carry-on. They are not allowed as checked baggage.

Personally if I were traveling with some of those LiPos (not particularly large) I would put them in one of those protective bags you can get for use when charging. That will isolate them from any flammable material if they do manage to go off, and the bag can usually be safely handled, probably even with a cell lighting up inside!

The main arbiter of taking them onboard is the rules from the airline. Check the requirements for all airlines you are flying on during the trip.

See you in April :)

G’Day,

What connectors do you need? We can prob just organise some batteries for you. AusRocketry carry’s varying types depending on devices being sold at the time, but if it is standard batteries for Altus Metrum, I’ll just get some in for you.

Cheers,

Blake

Blake, that would be excellent if you could get some. They are the standard Altus Metrum connectors.

So make it qty 2 400mah and 2 900mah. Sound okay? Let me know how to reimburse you.

Jonathan

P.S. We discussed whether a tower would be available for one of my projects. The diameter is almost exactly the diameter of a standard 3" airframe, 3.15", 80mm. 10ft or more would be ideal.

Replying to OverTheTop,

I checked Qantas and they say "Forbidden Dangerous Goods include "Lithium ion batteries exceeding 160Wh (not including mobility aid batteries)".

According to the calculator on[url]https://www.rapidtables.com/ca[url][/url]lc/electric/mah-to-wh-calculator.html[/url]
a 900mah 3.7 volt battery is 3.33 wh so carrying quite a few of these should be no problem.

I must be remembering the paranoia surrounding LIPOs when they first appeared.

Sounds like you are well within the required limits. Just remember to not put them in checked baggage.

G'day Jonathan,
I look forward to meeting you at Thunda. George loves the rocket you gave him and it flew perfectly on its first flight.

Cheers,
Pete
