Doesn't work that way.
You can't just FORCE a battery to charge "quicker" by using a higher amperage charger.
There is a electro-chemical process when charging and discharging and batteries will only take so much charge in without damage or other possible hazards like overheating or exploding.
HERE is some information to get you started on charging. There are lots of material out there that you might find helpful if you search for charging fla batteries..
Many of those 2/10/100A chargers attempt to force charging up to a certain point by boosting the output voltage and in the case of the 100A setting that is for STARTING surge, not for charging.
If you have been using portable chargers in an attempt to recharge your batteries "fast" that is why you are "disappointed" with them, no commercial made charger will do what you seek..
While one could "build" their own charger to force a higher acceptance rate, there is a fine line that is easy to cross that has the potential to blow your battery up and or kill you in the process. I would not recommend a DIY approach..
Batteries take time to charge, the more you take out of them the longer it will take to recharge, it is a fact of life.
Well, lets just say faster than the WFCO converter. I purchased a Schumacher SC1281 and it seems to work ok, am trying to decide if I want to keep it or go in another direction. I don't want to modify the WFCO in case I sell the trailer.
