I'm really impressed with this. I saw a review by Will Prowse on YouTube and it caught my attention. I am upgrading my camper to use a Lithium Iron Phosphate (LiFePo4) battery and I need a new lithium matched solar controller. It definitely helps and also has a thermometer to prevent charging or discharging the battery in low temperatures. There are a couple of USB charging ports on the front of the controller, making it handy for charging phones, tablets, etc. The instructions say you can buy a monitor cable if you want to use your computer to really dive into it. I'm very impressed with what I got for the money.
