NOCOGenius GENPRO10X3: 3-Bank, 30A Onboard Battery Charger - 10A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

Upgraded to lithium batteries for my 36v trolling bank so had to change out the charger for lithium compatible unit. Much smaller and lighter than 2007 Lund factory three bank charger. Leads were plenty long to connect batteries which are in two compartments. Both legs of charger leads are fused with micro blade fuses, not sure why both legs but sure can’t hurt anything protecting both positive and negative sides. Cables and terminals appear to be good quality. Simple set up to configure to lithium charge profile. Bluetooth BMS on batteries showed just shy of 10 amp charge coming into each battery, so seems to charge as designed. Switched to maintenance mode after each were fully charged. Three year warranty is nice on a boat electrical part.

Just what I needed, Thanks

I purchased this multi-battery charger for use on my live aboard sailboat. I have a lead acid dual purpose batter for starting her diesel auxiliary and a dual LiFePo4 house battery bank. This charger will replace the old charger which wasn't suitable for the LiFePo4 batteries.1) it is one solidly built charger! I feel confident it will be up to the task of keeping my electrical storage banks charged.2) can charge three batteries (lead acid, AGM, and lithium) at the same time.3) the instructions are easy to follow.This is certainly not a detractor but I do wish there were a way to connect the charger to my boat's AC power panel without voiding the warranty by cutting the three prong plug off of the power cord. I could, alternatively, wire a wall type plug from the power panel to plug the charger in but I would much prefer to hard wire it to one of the AC circuit breakers. I could also plug it into a DC to AC inverter. I'll have to ponder this a bit.But all in all I am, so far, happy and satisfied with this purchase and that it will meet my needs on the boat. Once I have it installed I will update my review with performance results.Update: I've had the charger connected and working on my boat in the local marina. It does it's job wonderfully. Keeps my house and starter batteries topped off and ready for use. I have no regrets with purchasing this battery charger and would recommend it to anyone looking for a quality product to maintain their boat and/or RV batteries.

The NOCO Genius GENPRO10X3 is a lifesaver for keeping my expensive batteries in top shape through the off-season. With 3 banks and 10A per bank, it charges efficiently and maintains each battery perfectly. I no longer worry about my boat or marine equipment sitting idle all winter—this charger ensures everything is ready to go when the season returns. The smart technology takes all the guesswork out, and the rugged build gives me confidence it can handle the job. If you want to extend the life of your batteries and avoid costly replacements, this is the charger to get!

I just changed from Lead Acid to lithium batterys, the greatesr thing is I did not have to get a new charger.I think the only improvement would be if the charger had two levels for rate of charge, I like tp slow charge mine if I dont plan on going out soon but like to quick charge them if I am going right back out.

Love this charger. 3 banks. 2 programmed for lithium trolling motor batteries and one programmed for AGM cranking battery. Sweet. Used for a couple of years now, no issues.

I recently changed the trolling motor on my boat and went from a 12V System to a 24V System. To do that I had to add another 12V battery, wire the TM batteries in series, and change the charger from a 2 bank unit to a 3 bank unit.The OEM charger was also a NOCO Genius but it was only 4 amps per bank. This charger is 10 amps per bank and although it was much larger and heavier than the OEM unit it fit back in the same place with no modification. It was however a bit of a chore reaching back under the back deck to get to the rear bulkhead where it had to be mounted. It can be done but your patience will be tested.The charger works perfectly. Charges quickly and then folds back automatically into battery maintenance mode. This feature will extend the life of your batteries exponentially.It's not a cheap unit but it's worth every cent I paid for it. Remember things are cheap for a reason.I highly recommend!
