1EON
as far as i can tell it contains 4 x 12v 75 ah powersonic lead acid batteries, I don't think they are deep discharge but are specified for UPS so should be fairly resiliant.
i'm looking at using these on a relatively small system perhaps a 125w turbine and a small amount of solar max 50w, so are these worth my while?
I reakon I can pick them up for £100 (about $190) and it would give me 300 ah at 12v, should be plenty for that charge power, good value?
what do you reakon?
