LiTime 24 (29.2) Volt 40A Mountable Lithium Battery Charger Intelligent AC-DC LiFePO4 Lithium Battery Smart Charger for 24Volt Lithium Iron Phosphate Batteries

I am thoroughly impressed with the build quality and real-world performance of this LiTime 24V (29.2V) 40A charger. To put it through its paces, I used it to sequentially charge two LiTime 24V 280Ah batteries. Each battery took roughly 7 hours to complete, meaning this charger ran non-stop for 14 hours straight under full load with absolutely zero issues. As someone who likes to verify performance with professional tools, here is the data I collected during the run: DC Output: Verified with a Fluke 378FC clamp meter, the charger maintains a rock-solid, continuous 40A output throughout the bulk charging phase. Thermal Management: The cooling system is highly efficient. Using an infrared thermometer, the hot exhaust air temperature stabilized at a remarkably cool 96.2°F (35.7°C). The main body stays well within safe limits, and while the DC output wires get slightly warm to the touch, it is entirely normal for this level of current and nothing to worry about. AC Power Draw: Monitored via a Kill-A-Watt meter, the unit pulls a stable 10.79A from the AC side. Connections: The included Anderson connection plugs are heavy-duty, solid, and provide a secure, low-resistance connection that minimizes voltage drop. Safety: The automatic cutoff works perfectly. The moment the battery reached full capacity, the charger safely stopped, and the LED indicator clearly switched from red to green. If you are looking for a heavy-duty, reliable, and technically precise charger for large 24V LiFePO4 banks, this is it. It delivers exactly what it promises on the tin. Highly recommended!

It is an amazing tool for charging your batteries.

Website poblem I had some problems with ordering and setting up an account. Summer got it squared away in a short time and all is well. Great customer service. My project is not yet complete. When it is I'll send photos.
