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

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

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.

Es terriblemente bueno

Love it! Charges my boats lead acid starting battery and my two AGM batteries

Works like it’s supposed to

Outstanding

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.

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.
