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 battery isn't just about powering the radio, it's about mobility. It facilitates the kind of adventurous, ad-hoc, pedestrian mobile operation that many KX2 users engage in. (Speaking strictly for me :) As a battery, the KXBC2 has proven safe and reliable by thousands of users. It's about 2.5 AH at 11 V, considerably higher in energy density than the battery packs in its closest competitors. I typically get 2 or 3 hours of hunt 'n' pounce operation at 10 watts. Eventually the radio will drop power to 5 W and carry on for another 2 to 3 hours. 73, Wayne N6KR > On Nov 6, 2020, at 4:26 PM, Rich NE1EE <[email protected]> wrote: > > Hi Bob, > Well, to get the ball rolling, I'd say no to the KXBC2.
