Repairs batteries!

I've used this charger a lot now. Not only does it charge well with many battery type options, it has a really good pulse repair feature. This repair mode has revived a few of my batteries. Well worth the cost.

Good quality and price

Happy with this charger purchase . Product is well built and worked as it should right out of the box. I have charged my 24 volt lifepo4 and my 12v agm batteries with no issues . Very easy to use . I would Definitely recommend this product.

Great for LiFePO Battery Re-charge

I bought this to charge my new 100Ah LiFePo 12.8v battery and it works as advertised, as well as charging other battery types.

Not worth the money

The media could not be loaded. I wanted to like this battery charger as an upgrade to the old analog ones that I've had in my garage foreverI was specifically attracted to the ability to charge lithium ion as well as having a repair mode for normal lead acidMuch to my chagrin there are some serious issues with this charger and it does not seem even remotely like it should be trusted to charge batteriesThe attached video and picture show an AGM battery that I know to work charge to about 10 and 1/2 volts which should still require further charging to about 12 and 1/2 to 13As you can see the unit recognizes that 10 and 1/2 volts as full, which even a basic battery charger for a 12 volt lead acid would tell you that it's notThe repair mode also does not work on lower voltage batteries as I've tried it several times. It only works on batteries that function which defeats the purpose of having a repair modeThe only pros that I can list here is if you don't have a battery charger, this could potentially get you 75% of the way there and it's modular both of the cables attach on each end making it easy to storeMaybe this is a failed piece of hardware that just needs to be replaced but brand new out of the box I wouldn't have expected to test it nor do most people have the testing equipment required

off grid game changer

So far so good. After struggling to find a 24v charger that worked with all battery types, this was a game changer. I use it to charge a 4 bank AGM battery system. I will be upgrading to lithium at some point, so this charger will work with that as well.
