At Battle Born batteries we take product quality very seriously, we also value the opinion of our customers.  This year we started a partnership with a professional bass angler.  We could not think of a better opportunity to prove that our lithium ion trolling batteries are the best in the market, than having them torture tested by a professional angler.  Bill Weidler uses our LiFePO4 batteries quite often, in fact he will tell you himself how hard he runs our lithium deep cycle batteries.
