Many larger class “A” coaches are opting to AGM batteries, particularly if they are all-electric rigs. This is primarily due to their cleaner operation and they are less ventilation dependant. We are, however, going to see even greater advances in the batteries from those we use today. They will offer more power, last longer and be far lighter.
One new offering that has shown up is the Mastervolt lithium battery. Currently it is only available in a 24 volt model, but a 12 volt is in development. Weighing only 115 lbs. its output is equal to four 8D’s. Keep in mind, the average 8D is over 140 lbs. That would mean the Mastervolt would supply the same power output at 115 lbs. that four 8D’s at a total weight of 560 lbs. could. In addition, the makers of Mastervolt claim the lifespan of their battery will exceed that of the 8D by three times.
Now don’t get ready to run out and buy one until you know the price. At about $7,500 each, they probably won’t be flying off the shelves anytime soon. Hopefully, after the introduction of a 12 volt model, smaller versions will become available as there are few RV’s that would ever need four 8D batteries. The future promise may be good as the prices will inevitably come down.
Not to be caught sleeping, Odyessy is redesigning a new AGM product. Using thin, pure lead plates, their new smaller package promises to deliver dramatically higher output with three times the lifespan.
Battery output and weight is important news for both the RV and the marine industry. This is because both rely on electrical power not only to start and run, but for powering the comforts of home when away from normal household energy.
