C35A smart battery charger
1: Can't reach the maximum charging current? To protect the battery, the system automatically identifies the battery voltage and selects the most appropriate current to charge the battery. When the battery voltage is low (for example, the 12V battery voltage is less than 11V), the system automatically charges the battery at the maximum current. (3 gears can adjust charging current, large current, fast charging) Problem.
2: The LifePO4 battery is not fully charged? When the battery is fully charged, it has a callback function, reducing the charge by about 1V-2V, which is normal. Added a small current after full charge uninterrupted charging.
3: Fan noise? It is normal that the fan has wind.

I love this charger! It's super easy to use even if you don't consider yourself very technical or handy.You do want to plug into the wall first and turn it on. Then select the mode for small battery (motorcycle, etc) or medium battery (standard car) or heavy battery (large truck). There is also a repair mode. After selecting the mode, connect the to the battery terminals and the charger does the rest.If you're getting this to charge up a dead car battery, plan to have it plugged in for quite a few hours or over night as it will take a while. As it is charging, the display shows Voltage used, Amps, Amp Hours, and temperature. It rotates through those items and one thing I wish I could do is to just have it display one of those only or allow me to manually rotate through the display items. I do love this little battery and it's been a life saver for me.

The product is easy to use. The instructions leave a lot of questions. If you hold the only button it has and it changes to 24v, what is the use of this? I have some large 12v 230amphr batteries I tested this charger on. The lithium batteries were 52% charged. This charger NEVER got above 30amps output at 12v. It shows it is rated for 35amps. I could have saved some money if I only wanted a 30amp charger. It has low/mid/high charge settings and then a pulse... It would be nice if the instruction mention this at all. You might be able to find a better charger for less money if you only need 30amps.

I did my research, and in theory this charger should work as advertised. It did not. We even had it tested, and it does not charge at 48v 13a. Bought the insurance, so hopefully we'll get our money back.
