You will enjoy the two Battle Born batteries. I installed them in our new Northstar camper which has just enough room for them. The nice part about the battery location in the Northstar is it's right below the dinette seat, so the batteries are always at inside camper temperatures.
I initially installed a Progressive Dynamics 45 amp lithium converter, but after some more research, and watching a YouTube with the CEO of Battle Born, decided that the way I use the camper doesn't work well with the Battle Borns and the PD converter that stays at 14.6v constantly. Yesterday I installed a different converter that better fits our usage. It's a WFCO 8950L2 50 amp converter. As we leave our camper plugged in sometimes for weeks or months to keep the refrigerator cold, the stereo set up the way I like it (Pet peeve on this camper), and to keep the batteries from running low due to parasitic loads, I didn't want the converter at a constant 14.6v.
The WFCO converter charges at 14.6V for up to 4 hours, then drops down to 13.6v indefinitely. Perfect fit for the Battle Borns and the way we use the camper.
One thing I noticed yesterday after I installed the new converter, when I fired it up, the batteries were down a bit, and the converter ramped up to 14.6v and 50 amps. After a half hour or so, the batteries were approaching full, and the converter started ramping down from 50 amps. It took 10 minutes to ramp down from 50 amps to 2 amps (full batteries, just running the lights & stuff I had on in the camper). I love it! My two Lifelines that I had before would charge to 90 some percent then take 8 hours(?) to get to full charge.
