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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excelente desempeño *by C***N on 31 May 2024* Lo compre nuevamente por su excelente desempeño ### ⭐⭐⭐⭐⭐ NOCO is the next best product for your boat! *by L***G on 20 May 2026* Love the this product best thing that I brought on my boat i am really loving how they have a prebuilt 5 amp fuse making easier for me to hook up and play and don’t have to go buy fuses to protect my expensive lithium batteries!
