CORE Chargers UAC40 vs UDC30

[Ted Maul]

Aside from the UDC30 having a separate mains power supply, is there a difference between the two? The pictures of the UAC40 suggest it has balance leads with it but the text suggests it doesnt (and pic not easy to tell so maybe they are just charge leads) wheras the text for the UDC30 says it has lots of balance leads.

I do have balance leads from a Flightpower balancer but assume these wouldn't fit into the Core Charger?

Thoughts on the two?
