Which is the better battery configiration
I am trying to learn more about 6 volts batteries versus 12 volts. I know the 6 volts can be drained further and recharged more (better lifetime). At least that is what I think is true. But it seems...
Forum Discussion
Standard 6 volt is the GC-2 give or take a bit it's 220 amp hours and when you put two in series it's still 220 amp hours (only now it's a single 12 volt battery electrically that is) Think 4D or 8D (Those suckers are heavy)
They can be taken down to 50% being true Deep Cycle before what I call "Rapid Aging sets in and if you do an OH CR** discharge (Say to 10 percent) Fairly good chance they will recover
Now 12 volts.. Starting batteries need to be kept full or close to it. Oh they can deliver a whole lot of amps often 2-3-4 times their AH rating but only for like 30 seconds.. But the total amp horus rating is usually less
Group 24 about 75 or less
Group 27/29 about 100 give or take 5
Group 31 130
So a pair of them 150 200 230
But with Starting batteries I'd limit discharge to around 20% of that or less
And do an OH-CR**.. stick a recycle sticker on it it's toast
With MARINE/deep cycle (Same capacities) around 25% or less
I've seen them recover from an Oh CR** but one.. IT was short term (Recharged quickly) and not many times. the GC-2s did a lot better.
Some folks talk about AGM batteries... Well I've not seen much improvement in battery anythign with AGM over Flooded wet other than you can mount them other than "This Side UP"...
LiFePO4 This is fairly new technology and I have a couple small ones for testing.
One is a 12 AH battery .. Can safely use at least 11 of 'em and unlike lead acid the voltage does not slide down (Kind of drops sharply near the end and though it does decrease as it runs down... It's not much of a decrease till the very end.
My test load is a 100 Watt ham transmitter draws 20+ amps at full power and really likes the LiFePO4 I also have a 10 AH one I've not yet tested with the TS-2000 (The radio) yet I did use it to power a freezer during a power fail. Nothing thawed.
The problem however is LiFePO4 takes a different charge profile so it is not always compatable with your converter or motor home / tow vehicle isolator.
You need some electronics added to the system to deal with it.
