NEXPEAK NC215 15-Amp Battery Charger, 12V 24V LiFePO4 Lead Acid Portable Car Battery Charger 9-Stage Trickle Charger Smart Battery Maintainer w/Temp Compensation for Car Truck Lawn Mower Boat Marine

Worked good for 10 charge cycle, Then stoped working. Dead display, no response.

I bought the NEXPEAK NC215 mainly to keep my 20Ah LiPo ham radio batteries charged, but it’s quickly become my go-to charger for just about everything in my garage. I’ve used it on 12V LiFePO4 packs, standard lead-acid car batteries, and even a few lawn mower and backup batteries I keep around—it handles them all with no problem. This is probably the best charger I've ever owned, and I especially love the indicator lights on the very clear screen - I can see what it's doing, what the temperature and voltage is and it's very quiet while it's working. The 9-stage charging system is really smart and gives me peace of mind that I’m not overcharging or damaging my batteries. The temperature compensation feature is a great touch, especially since my garage isn’t climate controlled—it keeps the charge safe and efficient whether it’s hot or cold out. What I really like is how versatile it is. I can switch between 12V and 24V systems, use it for trickle charging, or just top off batteries I don’t use every day. The display is clear and easy to read, and the overall build feels solid—definitely not one of those cheap plastic chargers you toss after a year. If you’re into ham radio, off-grid projects, or just want a dependable all-around charger/maintainer for cars, trucks, boats, or power packs, this one is well worth it. Pros: Smart charging, works with multiple chemistries (LiFePO4, LiPo, AGM, lead acid), temp compensation, solid build. Cons: The included cables could be a little longer, but that’s nitpicking. Highly recommend if you want one charger that does it all and doesn't feel like imported junk .

I’ve been using this charger to keep my 12Ah LiFePO4 battery, which powers my HAM radio setup, topped off, and I’m really impressed with its performance. The 15-amp output is more than enough to charge the battery quickly and efficiently, even when I’ve drained it quite a bit. I love how it handles the charge process smoothly and without issues, ensuring the battery stays in great shape. What stands out is how versatile it is—it's designed to charge both 12V and 24V batteries, so I know I’ll be set if I upgrade in the future. The charging process is fast but safe, with clear LED indicators showing the progress, which I find really helpful. The charger has several built-in safety features, including overcharge protection, which is a big plus for me because I don’t have to worry about damaging the battery while charging overnight. The build quality feels solid, and it has been reliable through multiple uses. It’s also surprisingly compact for how much power it delivers, which makes it easy to store and use even in a tight space. If you're using a LiFePO4 battery for your HAM radio or similar projects, this charger is a great choice. It’s efficient, easy to use, and gives you confidence that your battery will last longer. Highly recommend this for anyone looking for a dependable charging solution!

It works great. My $950 charger on my 38' boat wouldn't charge my marine AGM battery. And so I bought one of these to see if it would help. It desulfated the battery and fully charged it. The battery is back working great.

⭐️⭐️⭐️⭐️☆ (4/5 stars) **Solid Charger Once You Get the Hang of It** I picked up the NEXPEAK NC215 to maintain and charge both LiFePO₄ and lead-acid batteries, and it definitely delivers on power and versatility. I used it to charge the battery on my 2011 BMW, and it worked great—brought it back to life without any issues. That said, the interface and mode selection were a bit confusing at first. The manual could be clearer, but after watching a quick YouTube video walkthrough, everything clicked. Once I understood the button sequence and display icons, it was smooth sailing. The color screen is a nice touch, and I appreciate the temperature compensation and 9-stage charging—it feels like it's taking good care of the battery. Compact and easy to store, too. **Pros:** - Charges both 12V and 24V LiFePO₄ and lead-acid batteries - Fast 15A output for quicker top-ups - Smart charging with temp compensation - Handy color display **Cons:** - Instructions could be clearer - Slight learning curve for first-time use Overall, a great value charger if you're willing to spend a few minutes learning how it works.
