External battery for KX2, field day and SOTA

I'm hoping to get my KX2 for Field Day, and am looking to get an external
battery to use for FD as well as SOTA. I'm looking at the Talentcell and
Bienno 12v 12Ah ones. Anything specific to the KX2 I need to know about
external batteries? I know the internal one is more or less proprietary.

Re: External battery for KX2, field day and SOTA

Amazon is selling a 12v 6amp battery for $30 w/free shipping, fits in
the palm of your hand. Ordered one last Friday to use w/KX3...

The internal battery isn't proprietary. Elecraft has some made for them
with the power connector they use. I bought some spares from Tenergy a
while back and soldered on my own connectors. I'm not sure why, at the time
Elecraft had a shipping policy about more than two batteries I believe.

I have several Bioenno batteries I use on my KX2 and other radios. They
work great! I expect you could run the entire Field Day with the 12Ah one.

I, too, use Bioenno batteries. They work well, and I have tested the ones
I own under load, and the advertised capacity ratings are pretty accurate.
My one gripe is that the balancing circuitry is built into the pack. This
causes them to slowly self-discharge. The original A123 batteries use a
balancing system built into their specialized chargers, and they hold their
charge much longer. However, A123 filed Ch11, and they are now back in
production by a new owner. I don't know how good the new ones are, but
they are available once again through Buddipole. My now very old original
A123 packs still test out at 85% of their original capacity. They were
expensive, but they were a good investment. I've had them, I think, about
10 years--I used to use the S4P1 to power my beloved KX1, which at 14.2V
put out bookoo power!

Re: External battery for KX2, field day and SOTA

Morning Doug,

Like many others who responded to you, I use Bioenno LFP batteries to power my radios in the field. I currently have three packs, a 3Ah, a 15Ah, and a new 60Ah. The latter was purchased for Field Day and will power my K3, station computer, and whatnot in the field. (Yes, I’m going to camp for FD.)

I just received a new-to-me KX2 and have operated it with the internal battery pack a few times. For a short operation, like playing at the park, I think that power source is adequate. For a more substantial operation, additional power is appropriate.

As far as I can tell, the packs are radio-quiet and the 15Ah pack, which I’ve had for a year, is doing fine.

I considered a Talentcell for portable ops, too. But elected to buy a known-to-me quantity and instead bought a Bioenno 3Ah pack.

Have fun and 73 de AG7TX...
