This battery charger is absolutely amazing I have a $400 Snap-on battery charger/repair/ stable voltage charger that I attempted to repair two different batteries with one of them was a lie on that I allowed to go to dead the other was a motorcycle battery of a buddies that he allowed to go completely dead the Snap-on charger would not even attempt to repair them this charger repaired both batteries charge them up to full and they have now been functioning for multiple months I would highly suggest to this battery charger especially for the price

The 3 bank is massive, I’ll update when I get it installed. It looks very well built. I wish it came with ring terminal connections and not clamps, but ring terminals aren’t expensive. What I did like about this one was the ability to have the quick connect features like battery tenders.

I have only used this with LiFePo batteries (2x12V in series). The grounds are isolated so you can leave the batteries in series while charging them. Does what it says. I have had no issues charging the batteries.Just a little warning - Make sure you check the dimensions for your application. It is bigger than it looks in the pictures!But, it works well.

I really love this battery charger. This is actually the second one that I’ve ordered. We use it in our boat because we’ve been stuck out on the water before and the battery went dead. It’s definitely a lifesaver and it’s lightweight and it’s very easy to use in the last a while.

Replaced my onco charges with a pair of these after 3 fail oncos in the last 2 years. So far I am very pleased with the performance and the quality construction of these chargers. Very good quality. The lower price is just a bonus in my opinion.

Easy to read and install my old one lasted 10 years this one is a true 10 amps per bank

Very nice. Works well

Works well right now haven’t used it for a long time yet so we’ll see so far ok
