Got a K2 a couple seasons ago. Best battery I've ever used. Flew with it for 5 hours over two days without recharging. Ran the radio, two varios, a GPS and a Kobo eReader. Still showed 12.9 volts on the meter afterwards.

I have been flying with the LiFeO batteries for 3 years. They are still delivering the amp hours advertised.
