14.6V 10A LiFePO4 Battery Charger Special for 12V LiFePO4 Battery, Trickle Charger for Lithium Iron Phosphate Battery, Battery Maintainer, Built-in Safety Protections, Support Fast Charging

Works as designed. Charges very nicely.

This is a great little charger. I keep it in a weather box to keep my lithium battery charged for my crane winch for my truck. I've never had a single issue with it over 6 or so months and it lives in the back of my truck hooked up all the time.

Charger just arrived. It appeared possibly repackaged. Stamped into the unit was a notice to read the manual completely, but no manual was in the box. Gave 2nd star because it's not waterproof but it's raining and the charger hasn't been tried yet.Edit: Have now used to recharge seven 12AH to 100AH LiFePO4 batteries. This 10A rated charger completed charges much faster than smaller 2-5 amp chargers and shut off with 14.55 v holding in the batteries, so function is great. Changing to 4 stars. Still no manual -site should have manual available. Good price!

We have a 260AH LiFePO battery that had sat for a couple of months. It charged it in 48 hours. This was well within expectations. We bought this charger to charge batteries that weren’t connected to the RV in order to keep them fresh.Make sure the connections are secure on the battery. Many batteries have screws to connect the cables. Make sure the cables are disconnected and the screws on the batteries are firmly secured. If the connections are loose, the charger won’t perform properly.

It only ever charged 7a, not the 10 advertised. Worked for 3 months, within that 3 months I may have used it 10 times. Today it decided to start making a high pitched squealing noise while charging and the led was rapidly flashing green and red. Who knows what that means. Unplugged it, waited a bit, plugged it back in and now all it does is flash green, will no longer charge batteries.

A real good product 14.6 volts at 10 amps charges my solar battery 12 volt 100 amp an hour beautifully thank you

The description on Amazon says this is a charger for LiFePO batteries. You wouldn't know this otherwise, due to the poor documentation. There is absolutely no information on what batteries to charge. Nothing on the charger itself or their so called instruction manual, ( a small 2x3 inch ) piece of paper that is really a precautionary warning. I haven't used the charger yet, but my review is mostly for the lack of useful information for this charger.

For the price this is very difficult to beat. I used it to fully charge a new 230 Ah battery. It took more than 15 hours spread out over 2 days but it got the job done. As long as you handle it carefully this will do fine to charge your lithium 12v batteries. Just keep in mind the plastic and built is cheap but that is to be expected considering its price.
