Never used anything other than led acid batteries in an RV (standard and deep cycle), so cannot help with that. Never even heard of Battle Born batteries, must only be in the US. Our current RV (2008 Ford E450 based model) charges up several batteries with solar panels, and that runs all the 12vot stuff nicely, very nice to have for dry camping (no hookups).
We've had three RVs over the last 35 years or so, a van, and two class Cs motor-homes, one was home built (not by us), and the other was retail. Needless to say, if something can go wrong, it will on the first trip, and ever other trip too.
On our 2008 the water lines burst on the first outing and so we had no running water for that trip.
I think that was the worst thing, other than tire blow outs on the freeway. Luckily for us, it was always the rear dual sets.
