Okay, took a look at the IOTA 30 DLS literature. Its battery charger is a MANUAL two-stage charger, not the automatic multi-stage charger that you really want. (In essence, it's like the manual battery chargers that were available 30-40 years ago.)
With the IOTA 30 DLS, it's possible to over- or under-charge the batteries unless you watch it closely. If you rely on the IOTA 30 DLS to charge your batteries, you could easily shorten the life of your batteries and wind up replacing them more often.
I'd either keep looking or use the IOTA 30 DLS solely as a converter and rely on a separate quality multi-stage charger.
