Be very careful to charge Lipo batteries only with a charger specifically
designed for that type of battery, unless you don't value your K1 or your
home!!!

Subject: [Elecraft] Internal Battery Alternavives for KX1 ??
Hello Jay,
There is a LiPo 3.7v AA size available. Therefore, 3.7 x 3 = 11.1v in
parallel using the supplied battery holder but re-work the wiring between
the two holders could be a solution. This kind of battery will go up to
4.2v when it is fully charged so that the max voltage generated = 4.2v x 3
= 12.6v and still within the tolerance.
If your KX1 is with KX3080, then it would be a bit tricky in getting the
max power from the radio.

主題︰ [Elecraft] Internal Battery Alternavives for KX1 ??
I'm considering ways to increase transmitter power, by making changes to
the
internal batteries in the KX1.
I've seen a mod which added batteries. and a lot of other boards and
dangles.
In another mod, the owner just fabricated a larger KX1 chassis bottom and
changed battery holders to obtain 14V.
How about using six AA-size, 2.3 to 2.4 V batteries (if such things exist)
and the existing battery holders in the KX1?
Thoughts?
