Upgrading converter
Hey folks! I am looking at the BD 1255 MBA 55 Amp 4-Stage Main Board Replacement. I have a WFCO 8955 PEC. I am looking to upgrade to a couple Golf Cart batteries this year and we do a lot of boon ...

"The defect is that WFCO requires the voltage to sag below 13.2 volts during initial charge to trigger boost voltage. This is a nearly impossible task no matter how it is wired. In most cases it simply does not work."
It would better explain this to say the WFCO needs to see less than 13.2 as the "spike" when first turned on rather than a "sag".
If your set-up is such that there will be a spike of 1 volt when WFCO is turned on, then you have to start with the batt at 12.1 to see 13.1 at start, so it will go into Boost.
Problem is with long thin wires (higher R) and not so much of a bank in AH (hence higher R) your spike is higher, so it might even be 1.5v so now the WFCO needs to start with battery resting at 11.6 to see 13.1 after the spike.
