Good buy, quality item.
Worked well for what I needed.I used this for a solar project for my son. It has all the connections that you would need and is very well made. Good price for a good item.

Very effective mppt controller!
I use these to power solar Meshtastic LoRA Nodes. I have a 5v6w solar panel and 3 21700(4500mAh) cells in parallel. Output to the Meshtastic node. It has been up on my tower for 3 weeks and it has kept the batteries fully charged even during sub freezing Temps and multiple days of cloudy conditions. Very happy with the DFRobot controller. I have bought 6 of these now and would buy more.👍

Good, but doesn't restart if battery dies
Good product, works as advertised. Fully charges the battery from solar, and the reverse indicators are nice to have, just in case.Only con is that if the battery fully dies, the circuit won't restart outputting power to the load. It will recharge the battery, but I have to disconnect and reconnect the load in order to get power to flow again, which is obviously not ideal for applications where the circuit is less accessible. Paired with a large enough battery though, this shouldn't be a concern.

Just buy it already!
I bought this to control my 5v solar panel and battery charging for my Meshtastic device. So far this has been excellent at keeping my 10k mAh battery charged. Not only does it do great at charging in low light, the built in safety features are worth it as well.

Need a larger solar panel
With my 1/2 amp solar panel going through this device, no charge gets to a 5000ma lithium battery at half charge.Guess it takes a bigger solar panel to work. Connecting the solar panel directly to battery charges fine.
