Joe,

Why do you want 14 volts...Most radios have a 12 volt regulator that
drops 14 volts to 12 volts...I for years used 14 volts only to find out
is was not required. Have used 12 volts with no problems since...

single 14V battery.



Thanks in advance.
Er,... the terminal PD of a fully charged lead acid cell is 2.2V, so
6 of them in series results in a battery PD of 13.2V. As the cell
discharges the PD will gradually fall to some value under 2V (how fast
and how long this process takes depends on the rate of discharge and
the relative "health" of the cell. So you may end up with you battery
actually providing less than 12V for a good part of the time it is in
use.

I suspect that manufacturers put 14V on their kit to get across the
point that is well able to withstand the PD of a fully charge gell cell
battery.

Thanks for the reply.
The reasons I think I need 14VDC a
1.) That is what I received with the glider when I purchased it 2
years ago. ( 12 +2)
2.) The radio spec sheet calls for 14 VDC. It even states if you put
this in a 28VDC aircraft, purchase the 28 to 14 VDC converter. The
radio is a IImorrow Apollo 704. I am afraid to try 12VDC without
consulting directly with the manufacturer. Reason being that if the
voltage is below what it is designed for, some electrical/electronic
parts will increase the current draw (amps). Excessive current loads
can very damaging to electrical/electronic devices. I know it will
burn up motors etc.. but not completely sure about electronics. (I
am certianly not an electronic Engineer)

Let us know where you find a 14v charger.

Frank,

I recieved one with the glider. It doesn't state the Mfg. but it does
have a Part number, RR14650A. It is a smart charger just for 14 V
gell cell packs. I have seen it at one of the websites that sales
soaring supplies.

If I figure out which one, I'll email you.

Frank,
I bought one from tim mara last month.
He has them for both 12v and 14 v in his catalog.
Hope this helps.
Cheers! Pete Reinhart

I might add the reason for my request was that we are in the process of
realigining part of our club fleet. We use built up 14V, fused battery
packs that are interchangeable with all of our club gliders. We currently
have three 14V chargers, but have been avoiding including these battery
packs with our gliders as we'd also have to part with a charger (believed to
be difficult to replace). We also feel most buyers will likely end up
replacing our battery packs with 12V batteries and chargers at some point,
rather than maybe replacing bad 2V cells or even the fuse. So we'd be
unnecessarily giving up a maybe hard to get item in the 14v charger.
Appears not to be the case, although our chargers are a bit simpler
appearing than what's on offer.
