[Elecraft] K2-KBT2 battery

[JAMES ROGERS]

Johnny, LIPOs have a tendency to burst into flame if not treated with great care. I always carried my RC lipos in a metal container after having one burst into flame. Scary! 

I know some are using Lipos and they are a option, so please do not send me hate mail if you have gone that route. :-))

Rated at 2.9 AH, the gel-cel battery is extremely safe, and can be recharged inside the K2 continuously from the same DC supply used to power the rig at home. Power outage? No problem--you'll never miss a beat! (KBT2 not available for K2/100.)
