  • Cargador
It works very well and fulfills what it promises. I have used it to charge a LiFePO4 battery and so far I have not had any problems. It is easy to use, looks good quality and charges stablely. Good value for money.

  • Excelent purchase
I especially loved how small, compact, and easy it is to use and transport. My husband has used it on his motorcycle more than once, and so far we're very pleased.

  • Small package but very effective
This is a very nicely built charger. Compact in size but very effective. I've been using it to charge a couple of my 100Ah batteries for a while now, and it has not disappointed me. It's super easy to use considering it comes with an Anderson connector for your battery, making this a plug-and-play charger. Once you connect the battery, that's all you have to do. The charger will do the rest. For this convenience, it's well worth the price IMO. ... show more

  • very powerful, fast charging
VERY FAST- be careful hooking these up to cells that can't take the heat! This thing can pump up to 20A into a "12v" load. I charge my battery packs and this gets most of mine up to 10ah in barely a couple hours. Make sure to keep them cool/ventilated!

  • Heavy duty charger that should last quite a while.
I've got a lot of various chargers for multiple battery chemistries. This one is a dedicated charger for LiFePO4 batteries, which I like, since the other types that are hybrid just don't seem to charge them as accurately, and I would like to get the longest life battery possible of my investment.

I've been using this 14.6V LiFePO4 battery charger for a few weeks, and it's been a solid addition to my toolkit. As someone who enjoys outdoor projects, having a reliable charger is essential. This one is straightforward to use and charges my 12V lithium batteries quickly. The Anderson connector is a nice touch, making connections easy and secure. I appreciate its automatic function, which means I can set it and forget it without worrying about overcharging. From powering up my RV to keeping my marine equipment ready, it handles everything with ease. User feedback echoed my experience, highlighting its fast charging and efficiency. Overall, it's a reliable, well-designed charger that meets my needs perfectly. ... show more

  • Nice quality charger
This charger is very nicely made and worked like a charm on my numerous lifepo4 batteries. The charging indicator is kind of close to the cord so it was hard to see at first. You can tell when using this that it is a quality charger. I am going to make another adpter with alligator clips as well to plug into the anderson connector. ... show more
