Living with 600ah 6v GEL batteries
Update on these 660ah 6V batteries. I''m coming up on having these for 2 years now and they went from being totally awesome to absolute crap. SunEagle is right. Using the same panels, charge controller, inverter and load, I''ve got a "been in constant use", 6 year old 250Ah 12v GEL battery that now outperforms these things by a long way.
Advantages of 2 x 6v versus 1 x 12v?
I am planning a small 12v off-grid solar system to provide power and I''m looking at deep cycle batteries. What I''d like to know is why 2 x 6v is often recommended for such
Configuration/charging 24V system with 6V golf cart batteries
I am very partial to using four 6V golf cart batteries wired in series, creating a 24V 200ah battery. The GC batteries are pretty cheap and rugged present a meaningful amount of power To recharge them, you need a solar array of at least 30Vmp at 20A. Less solar increases the chances the batteries will not recharge fully and would begin to sulfate

Lead acid batteries 6v vs 12v and mixing | DIY Solar Power Forum
OK I am looking to get batteries. found some 1100 cc 950cca 6v industrial tractor batteries for $50 each or 1050cc 750 cca 12v marine for $75 What is better the 6v or 12v and can you mix batteries like four 6v and two 12v running a 24 volt system
AGM or GEL Batteries? Which is best?
Also, consider building the bank out of two series wired golf cart batteries (6v, 200ah) which solves the AGM "battery in parallel" problem. (AGM is so low resistance, that the parallel interconnect wires will steer power to one battery which will end up doing 80% of the work and fail earlier than expected)
Making a 12 Volt Battery Bank Using QTY 6 of 6 Volt
If you need a 650Ah 12volt system then you can find batteries in lower voltages (2v, 4v & 6v) at 600 to 1000Ah ratings. Trojan makes a 6v 695Ah battery like the IND13-6V. Just get 2 and wire them in series. The big question is how many watt hour does your battery system need to be and how are you going to charge it?

12v vs 6v Battery Bank
I use them in my offgrid solar unit. I did more research and the 12v vs 6v battery weights are very different. The 6v batteries weigh 67lbs vs the 12v batteries that weight 159lbs. So you are correct, that weight will be a big issue. I can make more room for extra batteries, but weight is an issue. Thanks again.

Is there any benefit to using 6 volt batteries instead of 12 volt?
When using 6 volt batteries you''ll need four batteries, @ 220 amps. 220 amps times 24 volts = 5280 watts (really 2640 at 50% depth of discharge). To match this battery size with
Which to choose? Between 2 150ah LifePo4 batteries
Perhaps this bat, ECI Power 12V 200Ah Lithium LiFePO4 appears to have a 150a BMS, there certainly are others with a 200a BMS 200AH. I want the battery to push 120amps since my microwave is about 1400 watts. I really only need ac for about 20-30 minutes total. Sokerdy claims to have a 150bms. I think they may be the only battery provider that
12v vs 24v battery bank amp hours
to use 6v batteries in a 12V setup, you SERIES them, battery_wire_diag.jpg (the top row of batteries in the sketch are in series) Batteries (pr PV panels) in SERIES, increases Volts Parallel, increases AMPS. Since Volts x Amps = Watts, either method still produces the exact same watts, but higher voltages have less losses, and a few % more efficiency.
12v 50ah vs 100ah
For a single battery that is AH times V. When you put two identical batteries in series you get the same AH and twice the V. When you put them in parallel you get the same V and twice the AH. Either way, you store twice the energy. So a 6V 200AH battery will be about the same size and weight as a 12V 100AH battery.

Then when the batteries reach end of life, get the Trojans. Problem might be the current from the new panel, once in place, will be max at 26.67.
Is wiring 6v batteries to make a 48v system practical?
Lead acid batteries are no exceptions and there is a scientific name given for it called Specific Energy Density expressed as Watt-Hours / Kilogram. Lead acid batteries in US Citizens terms is roughly 25 watt-hours / pound, or the rest of the world is 55 wh/Kg. To find a battery Watt Hour Capacity = Nominal Battery Voltage x Amp Hours. By now I
6 FAQs about [Solar forum talk solar batteries energy storages 6v 12v]
Can I use a 6 volt battery in series?
Yes, you can use two 6-volt batteries in series instead of one 12-volt battery. However, it's essential to consider Battery Quality. Using a Single String and avoiding PARALLEL STRINGS is a separate issue. Be aware that you are comparing a 6-volt setup to a 12-volt setup, which is not directly comparable.
Why are 6V batteries preferred?
The reason 6V batteries are preferred in solar panels is because they are more easily tested when wired in series. Get a bunch of current flowing (either charging or discharging) and measure the voltage across each battery to compare how uniform they read. A bad battery will be obvious then. When wired in parallel, it's hard to tell which battery is bad.
What happens if a 6V battery dies in a 12V configuration?
If a series pair of 6V batteries die in a 12V configuration, you're sitting in the dark, until you get the replacement member of the pair, and most people would recommend replacing both, to balance the load across both batteries. 6V in series = no redundancy, in that scenario. One significant reason, is AH per pound.
Are 6V batteries valid?
The reason 6V batteries are preferred is because they are more easily tested when wired in series. Get a bunch of current flowing (either charging or discharging) and measure the voltage across each battery to compare how uniform they read. (This guy seems legit)
What's the difference between a 6v and a 12V battery?
The 6V battery has 19 smaller and thinner plates per cell, while the 12V battery has 9 larger and thicker plates per cell. The 6V battery is lighter and slightly cheaper per Ah, but in this case, it might not make as much sense to choose the 1 x 12V option due to its heavier weight of 57kg.
How much does a 6 volt 400 Ah battery weigh?
A 6 volt 400 Ah battery has a capacity of 2400 watt hours. Given that the energy density for lead acid batteries is roughly 40-60 watt hours per Kg, this battery would weigh around 50 Kg. Therefore, a 12 volt 400 Ah battery would weigh approximately 100 Kg or more.
