agiletick Posted February 23, 2011 Report Share Posted February 23, 2011 what is the highest voltage you can run a 12 volt system at safely once i got my alt installed had to make custom brackets cause it wouldn't fit~ but the voltage is at 15.1 and i cant get to the vcm without removing the alt is this to high will i have to remove the alt and lower it Quote Link to comment Share on other sites More sharing options...

crunkjuice1 Posted February 24, 2011 Report Share Posted February 24, 2011 I have the adjustable voltage boost module and have agm batteries, I had called mechman and he said that was a bit high for my batteries and I should lower it.At the bottom of paper work it says, Maximum battery voltage levels for most manufactuers: 12 volt battery: 14.9 volts 14 volt battery: 16.5 volts 16 volt battery: 19.0 volts On paperwork for xspower batteries they say not to charge them at 15 volts longer than 5 minutes. Sorry if I am answering in wrong area but I am wondering the same thing on my alternator. Do you make adjustments at start up while engine is cold or wait until engine warms up to set voltage at 1000rpm? Once again sorry for my 2 cents.

skittlesRgood Posted February 24, 2011 Report Share Posted February 24, 2011 voltage will drop as the alt gets warm so if its set to 15.1v itll drop down to or below 14.9 Quote If I answered you in a well mannered, informative way, you asked a good question or had a good attitude.

crunkjuice1 Posted February 24, 2011 Report Share Posted February 24, 2011 I had left it at 15v and at idle it would drop to 14.9v but then I start driving and back into 15v it will go. Seems like I'm driving more than at stops so I see 15v longer. Quote Link to comment Share on other sites More sharing options...
agiletick Posted February 24, 2011 Author Report Share Posted February 24, 2011 mine stays around 15.1 if i let it run for awile it will drop to 14.9 was wondering if adding more batteries will lower this cause atm i only have 2 hooked up i have 2 more to add will more of a draw lower the voltage or will the alt still be putting out the same hate to lower it now then have to raise it back when i get other batteries installed Quote Link to comment Share on other sites More sharing options...
dugee81 Posted February 24, 2011 Report Share Posted February 24, 2011 I ran my kinetiks @ 15 volts and they bulged out, the one under the hood cracked and started expelling what smelled to be sulphur gases through the ventilation system. Made it very unjoyable to drive, along with it probably hurting my electrical. But then again, I ran kinetik. Xs is different, but I would just play it safe if I were you.. You won't notice any difference between 14.5 and 15, especially if your voltage drops down to 14.5 or more @ full tilt. Just my opinion.

BulletInjection Posted February 24, 2011 Report Share Posted February 24, 2011 14.9v If you are over 15v just turn your system up a little to drop the voltage "But officer my voltage was too high!"

crunkjuice1 Posted February 25, 2011 Report Share Posted February 25, 2011 OP I don't know exactly if your batteries are AGM but if they are I wouldassume the rules that xspower have on charging their batteries would apply to AGM batteries in general. The paperwork with xspower says not to charge there batteries at 15v longer than 5 minutes. I set my boost module to 14.9 at startup but even 20min highway drive it goes to 15v. I love how well the alt worksjust have to fine tune voltage boost module. I would try 14.5v for a week. Quote Link to comment Share on other sites More sharing options...
