Hey Robert!
How's it going?
Did you get the interface cable?

If you didn't perhaps someone in your club has one.
With it you can download the firmware updates from FMA's website.
I have two 10s chargers and running them both to charge my 10s packs
off my Iota 55 I will sometimes get the same low voltage messages you're getting.
My solution was to set the chargers at 4.5amp max instead of 5.0.
Good luck!
