## Questions & Answers

**Q: What is the difference between this and the iq-agm?**
A: The iq-agm is for charging an AGM battery. This is different than the more common lead-acid battery that most of us are used to.

**Q: Does this work with a 24v charger?**
A: Hello, If your DLS charger has the phone jack, it will work with 12, 24 (DLS-27 series) or 36 volt chargers. sincerely,John

**Q: Does this work with an intel power 9200 series ?**
A: The PD 9200 should have a built in Charge Wizard, which serves the same purpose at the IQ4. If it doesn't have the Charge Wizard, you want the Charge Wizard. The IQ4 will not work on a PD charger.

**Q: Why do i need this if 1 purchased the iota engineering (dls30) 30 amp power converter/battery charger**
A: I believe that the I Q4 smart charger equalizes your batteries once a week when left on trickle charge. The dls 30 is a battery charger but does not equalize your batteries unless the iq4 is connected. It basically turns it into a 4 stage charger instead of 3.
