In this video I show you how I am now powering my radios. If you are tired of lugging around heavy lead acid batteries, just like I was, then check out this video on the 12 volt 20 amp hour LiFePO4 battery by Bioenno Power! Bioenno Power makes batteries as small as 3ah (amp hours) all the way up to 300ah. Not only are their batteries great form amateur radio, but they are also used for remote control items. Aside from selling batteries Bioenno also sells solar controllers and solar panels as well. The customer service at Bioenno Power is beyond superior! I say this because of how they did a repair on my 120 watt solar panels.
