I purchase three of these beast to power my two hifonics on a 200 amp alternator pushing a re audio xxx 18 and they give me so much current. Its amazing, i can play my system without turning on my engine and still pump it up to 3/4 volume and only loose .3 volts thats how good these batteries are. They are on par with the kenetiks if you ask me there is no difference between the two i compared them with my friends kenetiks and they hold up the same. I would buy them again and again before i buy the kenetiks because you get the same power at a far less cheaper price so go buy them up guys they do work. Joseph from bridgetwon barbados.
