I have been reading about lifepo4 battery. There were some threads mentioning it to use for allo digione signature. Also on net, there is some good information about it. Though it is not very much. The impression i m getting, it is better than most linear power supplies. Is anybody using it.. so wanted to know their experience. I already have allo Shanti linear power supply and am thinking to buy one more for my reclocker. So i am confused. Also the 18650 lifepo4 battery and its charger are not easily available.
