## Questions & Answers

**Q: Can this unit be mounted outside to maintain batteries on utility vehicles ?**
A: While it is "waterproof".... It isn't element proof. Aka the sun would likely destroy the plastic after a while. Including the cables etc... This is designed for charging boat batteries. Or well that's what I bought it for. Maybe someone else knows more about it.

**Q: Can this unit be mounted outside for use maintaining utility vehicle batteries ?**
A: Yes.

**Q: Can this unit be mounted upside down. Where the wires would be coming out the top?**
A: Yes. According to documentation the unit can be mounted in any position.

**Q: With a 4 battery parallel array can the 8 charging cables remain connected while the batteries are supplying the load?**
A: The privies is to always leave the charger on the batteries.  Works great.  We use ours for lithium batteries.  Ours are in a series, I don’t think parallel would be any different.  One thing to note, it does way 40lbs.
