Steve,

SiO2 are slightly lighter than lead acid, and slightly smaller. The 100 amp-hour jar is a Group 27 iirc.


Regards, Don
My ride is a 28 foot Class C, 256 watts solar, soon to have SiO2 batteries, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.

I've had two LifeBlue 125 ah batteries for almost 3 years now. I have a Xantrex 2000 watt inverter connected to all the outlets in the TC and have 460 watts of solar on the roof.

I went with the LIfeBlue batteries as they have a built in bluetooth system that provides all kinds of battery info, takes the place of wiring in a system for the same info.

You have to get as much solar on the roof as possible, maybe just buy the one battery now and fill your roof with solar and if you need more then buy another battery.

Do however make sure you purchase a good MPPT controller, I us a Renogy, and get it large enough to handle maximum solar panels you will have on the roof.

Cheers,
Eric

Steve,

What would the advantage of six volt SiO2's be?

My FLA 6s are 230AH and 64lbs. The SiO2 6s are 260AH at 72.69 lbs

260/230 x 64 = 72.35

BFL13,

And two 12 volt SiO2 would be about 200 amp-hours--and at 20% state of charge would yield 160 amp-hours usable with 1500 cycles. A life time of use for most part time RV'ers. Physical size 27 kg (59.5 lbs)6.61 x 12.08 x 8.46"

Of course more capacity is better fir those of us who use large inverters.

Capacity. 260 AH for them, that always the advantage of a 6v GC battery weather it be SiO2 or lead acid. Li this doesnt realy apply because of the high capacity cell structure and the ability to arange them how ever you like.

SiO2 share that high capacity and you can arrange them however you like.

ahh but thats where the size and weight of the SiO2 become a disadvantage.

Steve as far as advantages to, SiO2 don't need a way to protect an alternator, nor do they need more than a garden variety converter, or battery charger. So the space taken up by the SiO2 may be less than what is required for an LiFePo4, and so may be the weight--unless we are taking a pretty large bank.
