Whats with the Watts? Most RVs use 12 volts - don't know of many that use 8, 6, or
2, volt systems. Some of the old time home inverter systems used an incredible 60 2-volt cells in series. I serviced such a setup a few hundred miles from here that had a 1980's 10,000 watt inverter and more than forty solar panels strung all over the roof and outbuildings.
With regard to spying on internal battery secrets of the AGM
It is a formula involving total weight, ampere hours and CCA. Given same construction (same manufacturer), if the weight of a single 6-cell equals a pair of 3-cells, and CCA (15-second ampere load test) are the same, then plate thickness has to be the same with both batteries.
I do not know how many folks here have played with recombinant VRB batteries. But it takes a lot of effort to get the tiniest amount of venting to occur. Venting is temperature sensitive and reactive with voltage values.
See the emergency lighting in public and private buildings? All of them rely on recombinant flooded VRB. Lead acid batteries. And a flooded battery WILL VENT BEFORE AN AGM WILL VENT.
Any unattended and un-monitored battery under charge is a risk. Severely overcharged, a bank of batteries beneath a motorhome living space (in a compartment) has a potential if severely overcharged to emit enough hydrogen and oxygen to become extremely dangerous if a source of ignition is presented. A lot of if's but if the wheel of luck roulette stops at 100,000,000 to one odds, the top half of the motorhome will violently separate from the bottom half.
Hypothesis cannot rule common sense deductions. I am trying to POUND IN THE POINT that a recombinant battery is not an IED. They can be safely ensconced within an RV, if reasonable precautions are taken to ensure reasonable security. No junk converter chargers, no unsupervised manual charging. Protection against unlimited short circuits (which will blow any battery recombinant caps, a hyper super duty ventilation system right through the roof of the rig).
Yeah I blew up lots of batteries on purpose. KA-POW! Flooded. AGM, NiCad (no NiMH). Calcium calcium, you name it. Messy. I had to worry about Pb flying off the concrete containment pad. Lead exposure of employees and the public. So I had to stop. But I did learn that abused batteries that electrolysized a majority of the H2O from a cell risked an INTERNAL battery explosion that tore the case apart and spewed boiling hot 2.300+ specific gravity electrolyte a considerable distance. Ever see a battery's internals? There is infinitely more "room" inside an electrolyte vented battery than inside a tightly packed absorbed glass mat battery.
If this does not render this issue in perspective I freakin' give up.
