Yes, the 120A rating is suitable for most alternators up to 120A. For higher-output alternators, consider the 230A version. This model is designed to handle the current from typical vehicle alternators.
The 230A can handle higher continuous current from larger charging sources or loads. The 120A is appropriate for standard alternators up to 120A. Choose based on your system's maximum current.
The current price is $52.63, which is a 51% discount from $107.50. Use coupon code SAVE10 for an extra 10% off your order.
Connect the combiner between the batteries: one terminal to the starter battery positive, the other to the house battery positive, and a ground wire. Follow the wiring diagram in the manual. Ensure the unit is securely mounted.











I installed this on my boat to combine the starter and house batteries. Works flawlessly. No more worrying about draining the starter battery. Highly recommended!
Solid unit. Does what it's supposed to. Only downside is the lack of a light indicator to show when it's combining, but that's minor. Overall happy.
This combiner has been a game changer for my RV. It intelligently charges both batteries without overcharging. Installation was straightforward with the included instructions. I've tested it with my solar setup and it's handling the current perfectly. Feels like a quality product, and at this price, it's a steal. Highly recommend to anyone with dual battery systems.
Had a similar product before, but this one seems more robust. It's been a few months and no issues. The wiring is a bit thick but that's expected for 120A. Happy with the purchase.
Installation took longer than expected because the manual is a bit confusing. Once I figured it out, it works fine. Probably great for someone with more electrical experience.
Victron never disappoints. This combiner is well-made, easy to set up, and performs perfectly. I use it in my campervan to keep the leisure battery topped up while driving. Now I never have to worry about starting the engine. Great deal too!
Installed on my truck to manage the auxiliary battery for my winch. It's been rock solid for six months. The price is right, especially with the discount. I'd buy again.
This is the second Victron product I own, and it's just as good. The intelligent charging is exactly what I needed. It senses when the start battery is charged and then combines. No more manual switching. At this price, it's a no-brainer. I'm telling all my friends about it. Installation was easy; took about an hour. Highly recommend!
Unit seemed fine, but I had to return it because it didn't fit my setup. My mistake though. No review on the product's quality.
I got this for my sailboat. It keeps the house battery charged from the engine alternator. Works as described. The only reason for 4 stars is that the LED indicator is tiny, but overall it's a good product.
Exactly what I needed. Shipping was fast and the discount made it a great deal. It's been working perfectly. I recommend it to anyone needing a battery combiner.
