i have a fifth wheel into which I have just "dropped in" 4 battleborn 12 volt, 100aH batteries. All batteries have been individually tested for taking and holding a charge (victron ip65) outside of the trailer and all test perfectly. indeed, I have 8 batteries although only using 4 in the bank in question, and trying all 8 at one time or another (two groups of 4) the batteries reveal no problems with individual charging and holding charges.
I am old and unwell, so I am stationary now, and on shore power 100% of the time, although fighting power outages and needing this all to work for critical reasons.
to do the trouble shooting on the problem as outlined below, all solar is switched off...meaning the array and the midnite 150 that controls it, so no solar part of my system is involved at the moment.
the trailer has a magnum 2812 inverter/charger, which also tests perfectly. in the process of trying to run this problem down, I have also tried a different 2812 which is also running perfectly and it has not changed what I am here to figure out. I am sure that the magnums and penals (have tested two and both work fine.
the firmware on both the 2812s and the magnum panel are current.
also, all charge cycles are taking place at the right voltages....for example, absorb at 14.4....and float at 13.6.
all wiring came from a highly recommended supplier, batterycables usa, to include that they connected all the lugs, etc.....and I am CERTAIN that wire sizes and lengths are not at any issue (these are wired as battleborn directs on their site and there is no question about the method of wiring in parallel for 12 volts.
the problem:
as soon as the charge cycle flips out of absorb to either float or "silent" (depending on how we set the magum panel...we have tried testing both ways)......................the voltage drops from a full reading (for these batteries that is.13.6 or even higher)...so quickly such that it hits 13.1 or 13.2 volts within a half hour...and flips right back into another full charge cycle.
nothing we know to do has changed this......and being on shore power full time, I cannot imagine what 12 volt draws there might be as things are, that would cause such a precipitous drop...and in any event, I have lived in this trailer for over 7 years and am unaware of any issues that would cause this to happen.
I am, indeed, 75 and not well...and trust that I could have done a better job this time in explaining my issue....but hope it is clear enough for someone to help me.
I live full time in this RV and even as I am on shore power, I am also in a place where power goes off frequently enough to be a factor.
I thank all, in advance, for any help.
