HI Tom, They are considered 1.2v nominal.
Charge range is up to 1.7v per cell. For a 24v system usually you pull out 1 cell or 19 cells 19 x 1.7 = 32.3v For a 48, usually 2 or 3 , or 37-38 cells. If you use much less, then the voltage swings really low, if you go more the voltage is too high for most inverters. The Iota isn’t going to charge them up fully with that low a voltage. But I don’t know if that version Iota is adjustable, many of the older ones had a internal pot you could turn up. But heck give it a try and play with it. jay peltz power > On Jul 26, 2015, at 4:34 PM, Tom Lane <t...@ecs-solar.com> wrote: > > I have a friend who has forty ( 40 ) Iron Edison Batteries , he says they are > each 1.5 volts and wants to use them for a backup to his aquatics business's > .
