Clearly these batteries will not fail from cycling under standard (77F, constant cycling, testing over a short period of time, ...) testing conditions, for just about all users.The cell data sheet that came with my EVE 304AH cells, show a "cycle life" of equal to or greater than 3500 cycles at 25°C (77°F). So if you look at that from a real world perspective and 365 days a year.....that would work out to 9.58 years. How many folks charge and discharge (One cycle) every single day of the year? Even if you are full timers and actually do discharge/charge every day.....the battery is not really being stressed if you are plugged into shore power (converter keeps the battery topped off). For well over the majority of us, who do not full time and use the camper on an occasional basis......even half of the year, that would theoretically double that 9.58 number to 19 years. If the data is accurate AND there is no premature failure, it's very likely that the battery(s) will outlast the trailer.
Deep cycle LA batteries are unlikely to fail under ideal cycling conditions for typical number of cycles that RVers use them. Testing cycle life could be 1/10th (?) of LFP. Also not having a BMS hurts LA in the real world from abusive conditions. LA do have a lot of premature failures in the real world.
