I'm going to second the Bioenno solution. I use the BLF-1215W and it kept
my KX3 running through Field Day last year along with some other shorter
term field events. I often run the KX3 at 3 watts when portable with
intermittent forays into 5+ watts when deemed necessary.
I have not had any issue

Right.
would you not agree that one benefit of Lipo 14.6 batteries is their voltage
being above the 13.8 spec?
Yes, but LiFePO4 are a better choice for most ham applications. The

Tom,
Consider cost vs. need and your intended power level.
If you are backpacking in, then weight is a consideration, so LiPo and
LiFePO4 batteries are to be preferred. IMHO
Hi Dave,
Most batteries from this company and all from Bioenno Power include the
electronics to balance charge between the cells. For Battery Space,
study the poop sheet for the battery you're looking at to confirm that
it's there. LiFePO4 batteries need specially designed chargers, and both

Do you know if this battery includes Battery Mgmt System?

Well, yes, that would be the fundamental difference between rechargeable and
non-rechargeable batteries. It wasn’t clear whether the original post was about
car camping or backpacking, so I offered the lightest solution.

Tom,
I use my KX3 for portable SOTA activation extensively. I do not worry
with internal batteries and instead, use a LiFePO4 battery exclusively.
When I did my research a couple years ago, I came to the conclusion that
for my style of operating, LiFePO4 technology is superior to regular
Li-PO b
I can vouch for the Bioenno Power LiPo batteries. Bought a 20 ah battery for
eComm and urban field work. It only weighs 6 lbs. A 10 h only weighs 3 lbs.

Yes, BUT -- you can recharge the LiFePO4 batteries 2,000 times. Those
non-rechargeable batteries can be used only once.

Maybe. The batteries in the boxes are kinda heavy.
For a shorter trip, non-rechargeable lithium AA batteries are great. They are
very light, about half the weight of NiMH batteries. At 1.5 V, 3000 mAh, and
0.5 ounces per battery, they have great energy density. A bit pricey, but you
could buy a

Almost any power supply capable of 9 to 15 volts at 2-4 amps.
Any family of batteries in that range will work. I use AGM lead
acid batteries for field day. I have a lithium family battery
for backpacking.
To calculate how much capacity (amp-hours) you need, measure the

I'm new at QRP and I'm about to head to a camp ground in a few weeks and go
portable. Besides using internal batteries, what longer lasting external
batteries are recommended? I hear of Lipo batteries and a slew of others.
