<div>Wrenches</div><div>I have had good experiences with these batteries and with the same issues with the magnum on 12 volts, don't seam to have any issues with my 48 volt systems.

<br>
They are considered 1.2v nominal.<br>
<br>
Charge range is up to 1.7v per cell.<br>
For a 24v system usually you pull out 1 cell or 19 cells 19 x 1.7 = 32.3v<br>
For a 48, usually 2 or 3 , or 37-38 cells.<br>
<br>
If you use much less, then the voltage swings really low, if you go more the voltage is too high for most inverters.<br>
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.<br>
<br>
But heck give it a try and play with it.<br>

> 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 . Continuous load 24/7 is only 365 watts with surges to 1200 watts . My guess is that ___# of batteries ( maybe 32 to 36 ? ) can be wire as a 48 volt system ? Any suggestion on charge controllers - Morningstar or MidNite ? . .? A Samplex pure sign wave inverter 2000 watts at 48 volts and an Iota 54 volt battery charger is my guess that it might be the way to power the load - any suggestions . Anyone have experience with Iron Edison .any suggestions appreciated ! Gator tom PS : any suggested websites ?<br>
