im45pl Posted September 24, 2015 Report Share Posted September 24, 2015 HI I don't think I have posted this question - had a quick look and couldn't see it... Anyway due to the awesome design of my VW I am highly doubting I can fit more than 1 alt in there and after talking to a few guys the biggest output I can get is 250amp... now my biggest issue is how to keep 12 x group 31 AGM batts happy? More for shows etc. as this car is not a daily and I highly doubt I will be running full tilt on the street, the amps in question are 4 x dc 5ks with about 4k on mids and highs. I was thinking of getting 12v power supplies as these can be had for around 50 bucks for a 50 amp unit, but my unsderstanding is they just dump voltage into the batts and this could be bad ( please correct me if I am wrong ).Unless it is possible to just turn them off when not playing/demoing. I was looking at xs lithium batts but the aussie dollar is just too weak at the moment and I already have the the 12 batts any ideas? cheers TEAM DC AUSTRALIA My_Build_Log Link to comment Share on other sites More sharing options...
Clownrock95 Posted September 25, 2015 Report Share Posted September 25, 2015 Some dual alt setups replace a existing component like the a/c compressor (y'all Aussies don't mind the heat right?lol) from what I hear so maybe look in that direction short of that a xs power intellecharger and a generator lol Link to comment Share on other sites More sharing options...
crispy_chick3n Posted September 25, 2015 Report Share Posted September 25, 2015 could look into having an alt custom wound, would probably cost a pretty penny tho This page is crispy_chick3n approved. © crispy_chick3n inc Link to comment Share on other sites More sharing options...
MrSkippyJ Posted September 25, 2015 Report Share Posted September 25, 2015 You don't want to let your alt do the charging, that is hell on alts. Really the only good way is to get an actual 12v charger like one of the ones XS provides.

I wouldn't rely on just alts TEAM DC AUSTRALIA My_Build_Log Link to comment Share on other sites More sharing options...

MrSkippyJ Posted September 28, 2015 Report Share Posted September 28, 2015 Keeping batteries maintained, but if you constantly have a bank of dead batteries that the alt is the sole source of charging watch how long the alt lasts.

So what happens if you turn on your accessories, like headlights, ignition, AC, heat, amplifiers that draw +100A? Where do those amps come from? Thinking is the root of all problems...

MrSkippyJ Posted September 28, 2015 Report Share Posted September 28, 2015 it still won't be a constant draw. The accessories might be but it won't be that much. The amps aren't likely drawing full current the whole time either. Amplifier draw is very dynamic which is much different than the static load that a bank of dead batteries would put on an alternator.

Miguels Posted September 28, 2015 Report Share Posted September 28, 2015 Skippy is right Skippy, you also have to see it this way. Nobody has the alt power to sustain the amount of amperage needed. Even with dynamic music. Dead batteries do kill an alternator quick but same happens if you play full tilt all day and don't have the alternator power to sustain 13.8v. You will always see people dip into the low 12's and keep it th at way. That puts strain on the alternator and kills batteries as it does and eventually kill the alternator. That's why charging batteries constantly is a must. my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
