I have in excess of 13 Kw of chargers and that's a lot of energy. Maintain voltage control of a power source addressing a Lifeline and the battery will take care of itself.
1. Baldor 8.2 Kw 3 phase ferroresonant charger configurable
2. Allied 2.4 Kw 12 or 24 volt single phase charger (230 lbs!) USN
3. Trace 4024 120 amp charger
4. Delco 50DN 385 amp 24 volt alternator
5. Niehoff 24 volt 400 amp military alternator (Quicksilver)
6. And an assortment of 300 or so amps in small power supplies, including the Borg, and the Hyperwatt and 5 other power supplies.
I have more charger capacity than what the 6 cyl Kubota can handle.
A person would have to lay out careful plans to enable thermal runaway on a Lifeline. I agree with Lifeline that TR is unlikely. Their conditioning exercise takes the battery into the 17+ volt range.
What I seek is minimal generator run time, not a plastic goblet trophy from Guinness.
Jamming more amperage into the (Lifeline) battery has diminishing time reduction returns after C1 has been reached. But the time savings at C1 versus what standard converter output offers is appreciable. I can take both the standard and the 2-story from 50% SOC to "the wall" in slightly over four hours. Start the generator at 0800 and shut it off for lunch. But I have 24 wet cells to deal with -- worst case.
If I am running the diesel and power is restored, the diesel undergoes a 7 minute cooldown for the turbo and then it is secured. The single cells get 120 amps from the Trace and the Borg and Hyperwatt take care of the Lifelines. The Hyperwatt is a 56 amp Megawatt (highly modified) and the BORG is 2 Hyperwatts 112 or so amperes. CFE asked me if I would like to swap out my old-fashioned mechanical meter for a modern digital meter and I told them "In a pig's ***"
I have yet another 400 watt, Meanwell that is set on 13.5 volts to float the Lifelines and act as a UPS for my Respironics CPAP. Used to be a BiPAP until I was forced to rebuild it.
Looks like the power commission is improving reliability of the grid. Other than summer storm outages we might have dependable power. No matter how it's dealt .65 gallons per hour is $2.60 and a sixty plus mile drive wrestling drums in Jesus' Toyota.
Hope this helps
