Most of the competition includes the Anderson connectors for your wires you are connecting to the dc to dc charger. I was not able to source them local so had to oder them and it delayed my install

It is crazy, i thought I did something wrong, but nope. This will draw 20w from your auxiliary battery all the time. What does that mean in practice?Lets say you have a 100ah battery. This will SUCK 25% of you battery every single day. All of that is just being converted into heat.This also means that if you pump 100w through this, your battery will only get 80w, because again this thing is basically heater.

I've done the Renogy game and detest the pricing and support. I have not required support on either unit I have purchased from these folks cause, it's just that good and easy to install.
