1. A caution on Hobby King. They are indeed very cheap and supply
stuff in a moderate time, but basically you should write off any order
with them that goes wrong. I have had about 6 orders with them. One
where an item went out of stock between my ordering it and them
preparing the order. They wont tell you, your order will sit "pending
completion" ie till the out of stock item comes into their warehouse
(which may be never). Also had a second one where they sent me someone
else's order (I assume they got mine which was the better deal for
them!). Have been "negotiating" with Hobby King for a resolution since
November (yes 5 months now). They have processes which must
be follow but no-one at their end seems to understand clearly what
they are.
2. Battery tester for capacity requires some form of voltage
measurement over time with battery discharge. To make the test
reasonably quick (ie an hour or a few) requires a moderately high
current rate which you could do with spotlights or similar. You can
then (knowing the current and voltage) work out the battery capacity.
I don't believe any kit manufacturers would do this. I have done this
recently with AA batteries playing around with a PIC type
microprocessor. I also worked out a method for friends of mine in the
90s who were into RC car racing in a big way, when NiCads were the
only batteries around and capacity was critical to them. The problem
always is to waste the heat energy at the rate you want.

Ross is keeping away from batteries being sold from China. I have no
experience of this, but modeller friends, use “Hobby King”
–based in Hong Kong - extensively, with good results.
I have not checked, but no doubt Altronics can supply you with an
adequate kit to build a useable SLA battery tester too! However if you
are regularly doing 10 or more hours in a single flight, without
battery depletion problems, then I suggest that you do not need a
battery tester.

First up the fishing rod:
..it is 2014
After a long debate - they did put the internet on computers. ;-)
There is a handy search engine that works in a web browser - it is
called Google.
can be found at: http://www.google.com.au [1]
type in "FNB-64" into the search.
and on the first page you will find something like this [2].
..and here is a fish. [3]
You could get really adventurous and do a search on Ebay [4]
and get a result such as this [5].
And now let's make this thread a bit more interesting:
I would like to find out about the Ebay experience of the people on
this mailing list with purchases such as batteries for hand held
radios?
And: what are people using to charge their SLA glider batteries (what
is the BEST charger?)
Do I really need one of them? [6]
What is the best test to find out what capacity the glider battery
actually has - not just what is written on them.
What is a good SLA battery tester?
I went through the archive of this list and found LiFePO4 being
mentioned.
Who uses LiFePO4? Interesting article here. [7] What is your
experience, how long have you used them now? Are they worth it?

I am hoping someone can help me find a battery supplier for my VHF
Handheld radio, the battery has finally given up.
It is a VERTEX STANDARD PRO V, VXA-150, and the battery product
number is FNB-64.
Thank you for any assistance.
