I often operate my KX2 from the internal battery. As a "backup" source I frequently just take a second KXBT2 along. When you plug it into the external power jack the KX2 will draw it's power from the pack with the higher voltage. Tim N9PUZ On 11/6/2020 6:56 PM, Wayne Burdick wrote: I would d

The 12V Bioenno batteries have an internal battery management circuit. They require 14.6 - 15 Volts input to charge properly. The BMC will prevent overcharging and Bioenno Support says it is safe to leave the charging voltage permanently applied. Tim N9PUZ On 11/6/2020 5:06 PM, Bob Conder via

No - the KXBC2 is not suitable for the Bioenno BLF-1203W, you should use the charger sold by Bioenno for this purpose. Bioenno products are LiFePo, a different kind of LiOn Chemistry than the Elecraft ones. The Bioenno charger will work for all the higher AH batteries they sell that have the DC Ba

I would definitely *not* use the KXBC2 charger with anything but a KXBT2, or an exact equivalent pack, for safety reasons. The voltages and currents are targeted specifically at 3 Li-Ion cells (11 V). Just to give you another [probably biased, beware] opinion on the KXBT2, though: The internal

Hi Bob, Well, to get the ball rolling, I'd say no to the KXBC2. I use several different sizes of the Bioenno LiFe batteries (see earlier threads this summer for a detailed discussion), and I vote to use the proper charger. It's only a few bucks more...on the road, I use an inexpensive converter

KX2 External battery question: 1) Will the KXBC2 charger work with a Bioenno BLF-1203W LiFePO4 battery?orĀ 2) What are very lightweight external batteries that will work with KX2, and not add significantweight while hiking or backpacking and doing SOTA?Tnx in advance,Bob K4RLC __
