WF-8955 where is the other fast charge?

So its raining and I am trying to learn the new trailer and nothing I try seems to be able to pry anything more than 13.6 voltages out of this supposed 3 stage charger. Where's the14.4?! Even with drying as low as iamwilling to on the battery Max is 13.6. Seeing other posts it seems like I am not the only one. Is there any solution to this ( don't need to know about competitors products, thanks)

    You need sufficient load or battery draw to have voltage AT THE CONVERTER sag below 13.2 volts.
    Not an easy task actually.

    Far better to get a PD9260 or 55a IOTA with IQ controller.

    You can attempt to remedy the situation by increasing the cable size from the wfco to the battery bank. Try #2. You can move the converter closer to the battery bank using thicker wire. Neither of these suggestions work all the time, or even most of the time.

    You MIGHT be able to pop the box and twiddle some internal knobs, but don't do so unless you are fairly expert. You may let out the magic blue smoke. In which case you may want to change brands.
