[QUOTE="Jonnyswboy, post: 8752017, member: 677275"] How long does it take until the alternator is loaded? I will probably evaluate the performance of just the two banks and then consider adding more. Do you think that I would even be able to clamp 7-8kW with just 80AH at the expense of the longevity? Is doubling to 160AH the difference between holding 15.2-14.7 or dipping to 13.3-12.5v? I just want to know how long I can draw 700-800A from my system before the battery is dead and I am just using alternator. (Not that I want to cycle the battery several times a day). I've seen people running similar setups and they report positive results. One guy I talked to had one 80AH on a BC17k at 0.5ohm on one 390A alt. Thanks. My previous build was 1500RMS so this kind of power draw and lithium are new to me. [/QUOTE]
