Replacing a cheaper Northern Tool controller. Like this one much better due to the red LEDs that give the approximate state of charge of the battery. Hard to beat the price for what you're getting.

Works fairly well. Draws ~13-18mA depending upon voltage off the battery constantly. ~3mA of that is in the LED's (depending again on voltage) and the rest is just running the on-board electronics. I also wish the battery status led's were a) dimmer or b) turned off at night. I adjusted the internal pot so that the LED's turned on/off at more useful voltages (12.9V, 12.0V) The lowest LED cannot be adjusted (~9.2V). The unit will automatically disconnect loads at somewhere between 10.5-11V (which is nice for preserving standard chemistry batteries). Can't beat the price. Nice internal heat dissipator for the power electronics with proper thermal interface material. Nothing fancy but pretty well made.

It may be too early to write reviews but this review is just based on my initial observation. So far it worked as described without going into technical details. I think the setup is good for an in-expensive regulator. Instructions, clear. I like that it has a battery power indicator (3 LED's). Four star is because at night the LED lights are still on. it doesn't consume much power but still consumes a little even without a load. I have a harbor freight regulator on one of my setup and all the LED's will turn off at night (means no charging from the panel). This is just so inexpensive to pass up and try. After discounts on HF this is still about 9 bucks cheaper. If everything goes well, this will be a good solar car battery maintainer with a minimum of 15W panel. My setup for this is just a regular car battery, a 50W panel laying flat on top of my sunroom, wired with low voltage 12g wire and a 300w inverter (kinda like a UPS). I use some of the stored power just to light up my computer desk using 12v car LED lights. My other setups is another story (like you!-a mad DIY scientist). It did help power my Uverse UPS for modem and phone for an extended internet access, when the power went down.
