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 ...

With the WFCO it should be at 13.6ish now and it is. Good to go! :)
You will only see the WFCO go into boost if it sees that 13.2v trigger, which it might if your batts are really low when you start the recharge. Many people never see theirs do 14.4 the way their RVs are set up.
The PowerMax goes into boost at first every time it starts (I have those) and then drops to 13.6 after a set time. Depends on the model how long a time it stays at 14.x. Some were only for 15 minutes same as Iota's 15 minutes. The newer LK models do 30 minutes. That is too short in many cases.
However, you can choose to use the LK model in its adjustable voltage mode, where you dial in say 14.7v and it stays there till you dial in some other voltage. That is perfect! You leave it at 14.7 until the batts are truly full (near zero amps and SG right up) and then you dial in 13.6 and it stays there till you change it.
I am not sure you can get at the adjustment dials with the MBA LK lower portion installed like in their picture. Seems to me it has to go in facing the other way to put the adjustment dials up front where you can get at them. No trouble with the deck mount LK of course--set it down how you like.
The PD might do 14.4 at first depending on what it "sees" but you can use the Charge Wizard to make it kick up to the 14.4 and it stays there for four hours. That works too but you can't pick other voltages.
Since off grid you only do 50-90s at most or 50-80s on gen time you just leave the LK at 14.7 and shut off the gen when you like. The batts will not be full but be as high as you have time for. Then at home, you plug in and at 14.7 get them full and now dial in 13.6 until next time. Gottaluvit
Your no- load amps look very good. There are always some tiny loads like the LP alarm or radio memory.
Good idea to have a spare charger along anyway even if you are on shore power in case the converter dies. You can carry on getting 12v from battery and recharge as required with your portable charger plugged into shore power. It is not a converter so you can't just leave it on. So you don't have to go home. "Be Prepared"
Ok so IMO your best bet is leave the WFCO as is, and get one of these as your portable charger (assuming you have a 2000w gen, not a 1000)
