  1. Hey guys, just had my first professional install done on my Lexus ls430...the owner of the shop happened to have a similar model Lexus, so that was really cool. What I had installed as listed ---20 foot of Wirez signature 0 AWG copper wire ---Wirez Mini ANL 0 AWG fuse holder (w/ 150 Amp fuse) ---Wirez Fused Distro Power Block - 2 Amp Anyhow, I have a few questions... 1. What is the biggest Amp I can throw on here without adding a secondary battery? 2. If I added a secondary battery in the back and ran the 0 AWG directly from alternator to secondary battery (in this case it's gonna be either a JY power 45 or 79 AH 12 volt lithium ion battery.....would the 0 AWG be enough to charge this battery effectively so that I could power a large amp (eg. 3000 watts RMS or greater? I am just wondering how many batteries I can effectively charge without putting too much strain on the alternator...and of course I am considering getting a HO alternator... 3. If I throw on a 240 Amp Alternator, how can I limit the amount of current that is drawn through the 0 AWG into the secondary battery? eg. do I need a battery management system of some sort?
