I have installed two golf cart 6 volt batteries.
With that said; Is it safe to take them lower than 50% discharge. Reading my digital volt meter at what point is a good number at which I should start charging.

Dave, Golf cart batteries cycle better than do the more common 12 volt marine batteries, but taking them below 50% on a regular basis will still reduce their lifespan. At 12.2 volts, your batteries are roughly at 50% charge, so they should be recharged at that point, if not before.

Giving it some more thought; there is no difference between 1 - 12 volt verses 2 - 6 volts? ------------- Dave & Joyce Never Forget, In God We Trust; This Our National Motto. Member; Patriot Guard Riders, Michigan Chapter Retired; So Every Day is Saturday.... Except Sunday |

The difference is two 6V batteries will generally give you much more capacity than a single 12V. Even two 12V batteries of the type usually employed (GP24, 27) are less capacity. And it's a fact that individual 2V cells like to be used in series, not parallel. It helps in equalizing the loads.

Either way it is a 12 volt system and the batteries function the same, just with more lead mass with the golf cart batts, which gives you more available energy. The rule of thumb is stay above 50% DOD most of the time, an occasional dip below that is ok but never go below 35% DOD. This is followed with most off-grid solar home systems. ------------- Doug ~ '10 171 (2009-2015) ~ 2008 Salem ~ http://www.rpod-owners.com/forum_posts.asp?TID=1723 - Pod instruction manual

Thanks for the reply.
DOD? Meaning? _________ of Discharge ------------- Dave & Joyce Never Forget, In God We Trust; This Our National Motto. Member; Patriot Guard Riders, Michigan Chapter Retired; So Every Day is Saturday.... Except Sunday |

DOD, short for the Depth of Discharge, is used to describe how much the battery is discharged ------------- JandL 2013 Honda Ridgeline 2012 177 2 Paynes in a Pod |

Inversely, SOC is state of charge. 20% DOD = 80% SOC. Sorry I didn't decode DOD earlier. ------------- Doug ~ '10 171 (2009-2015) ~ 2008 Salem ~ http://www.rpod-owners.com/forum_posts.asp?TID=1723 - Pod instruction manual
