NOCO Genius GENPRO10X4: 4-Bank, 40A Onboard Battery Charger - 10A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

NOCO Genius GENPRO10X4: 4-Bank, 40A Onboard Battery Charger - 10A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

Q: Can this unit be mounted outside to maintain batteries on utility vehicles ?

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 upside down. Where the wires would be coming out the top?

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?

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.

Battery charger for my bass boat

I put this in my triton bass boat and it works great. Highly recommended it.

Great charger!

I love this charger. Pros: Each of the four charging banks can be set for wet cell, AGM, or Lithium batteries. I use it to charge four lithium batteries in my boat. Each battery type has a different indicatory light and charge indicator lights let you know what stage of charge the battery is in. When a battery is charged, you see a nice, bright green indicator. Great charger. Cons: It's expensive (but it's got the features and battery management I need), big and heavy.

Must have.

Does exactly what it supposed to do charges my batteries on my boat plug it up let it charge up my batteries for a worry free day on the water the next day and it seems very heavy so that tells me hopefully it’s very well designed and built.

Seems to work, but...

I made a poor choice in ordering this. I'd purchased four LiFePO4 batteries for a power bank. The manual for those batteries indicated they should be charged independently before connecting them in parallel. This fit the bill.And it seemed to work on the three or four occasions I've used it (although it indicated a problem with one of the batteries, and didn't charge it, on one occasion but not the other occasions).Unfortunately, the four channels can't be run in parallel mode, so it can charge the entire wired-up bank at only 10A. I was hoping it would be a suitable component for my overland truck setup - to take advantage of "shore power" - but it's big and heavy and would take forever to charge the bank.It seems sturdy and well-made. I didn't have any reason to try out the other modes or the more advanced features.
