[RE-wrenches] Battery Watt hours FLA VS Iron Edison Batteries

[Dan Fink]

Tom, Dana -- I'm quite happy with the nickel iron battery bank that runs my
office. But you as the installer have to deal with the odd charge /
discharge curves and program the equipment to work with that. Just like any
other battery technology that is not lead-acid.
