  1. The vents for xs batteries are just underneath the label on the top of the battery. If they are venting they will start to push upwards and you will see a crack in the label on the battery. I highly doubt you have had this happen. Ive had my xs batts at over 15.4 when it was colder than 30 degrees outside. It stayed in that voltage for about 45 minutes of my drive and then went to 14.4 where it needed to be. Ive seen several people run at 15v flat with a 12v battery without any problems but it can shorten the life of your battery by doing so. I was thinking of getting an adjustable voltage module from mechman but as my truck never charges less than 14.45v i am just going to leave it as is.

    good to know, I don't think I have seen any splits on the label. They seem to be holding the charge fine still.

  2. So, what are some signs of XS Power batteries venting their oxygen? I read charging over 14.9 can cause this. I am asking because while I was having some trial and error time with my Mechman 270 trying to get the AVBM set right I did occasionally over the course of a couple months, charge 15.0-15.1 while driving at highway speeds. I finally have it set to 14.9 on cold start up and after stop and go driving it settles down to 14.5-14.6 idle.

    I'm just really scared of ruining a 300 dollar battery. I didn't see any other thread on this particular subject so I figure it may help someone else in the future by knowing what to look for.

    Thank you all for any help.

  3. I purchased a Sundown SAZ-4500D from him and it was a pleasant transaction all the way through. We had numerous conversations through text, none of my questions were ignored leaving me to feel safe spending over 900.00 with him.

    He lives in California and I live in Florida, so needless to say I was nervous sending that much money to someone so far away, but in the end I am Satisfied as everything is delivered as promised, exactly when promised.

    No need to fear when dealing with him!

  4. Love my Mechman 270 amp alt! I got it a while ago and did the Big 3 but never posted any pics! how could I!?

    but im learning after reading here that I'm supposed to run a ground from the grounding stud on the alt to the batteries ground (disregard the mismatched electrical tape, that is hidden by covers). I was not aware of that and I ran it to the engine block instead. I'm not having any problems so should I just leave it there and add another ground from the alt neg to bat neg?

  5. I just plugged mine in for the first time today and the charging light turned orange (means its charging), then literally 1 minute later the light was green. Is that normal? there's no way my batteries are in that good of shape after the use they get. I just want to make sure the chargers not bad or my batteries are not bad.

    so I left it on the charger for a few hours and when I turned the car to ACC (just battery power) to see what they were resting at(stinger volt meter), it was at 13.1 then a fews seconds later 13.0 then 12.9. do I have a bad cell?
