Latest battery arrangement for KX1

[PHILIP GRAITCER]

I love my KX1, but powering it with 6 AA Lithium cells puts out just 1.5-2.0 watts. I’d like a little more umph, since most of the time I use the KX1 in the field, so I also have a less than optimal antenna.

I’d like to power it with 12V, but prefer not to use an external battery. Just gives me too much to deal with.

Has anyone rigged up a way to power their KX1 with internal LiPO batteries? If so, what make and model. If the batteries are internal, my feeling is the best way to charge them - to avoid fire hazards - is by removing the bottom half of the case.

I realize the battery world is changing rapidly….

Anyone have recent experience with this?

I put a couple Zippy brand LiFePO4 packs in series in a replacement case
back for this purpose. I'm no big fan of Zippy brand, based on my past
experience, but these were OK and  work fine for me, though only 700 mAh
capacity. Already had a balance charger for them.

My little 750 maH Li-poly would fit inside my KX1 if I remove the AA
battery holders.  I say "would" because I haven't done it and won't ever
put an Li-Poly-anything *inside* a radio.  I had one that I got at the
local RC Model shop catch fire while I was in the Spartan Sprint,
discharging it.  I was able to pull the power plug by the pigtail and
fling it over the deck rail onto our gravel driveway.

YMMV

I ordered a new top cover for my KX1 and installed two LiPo batteries into
it. Though the exact model of battery is no longer available I'm sure there
are others that will fit:
