5Great charging relay for a second battery in VW vanagon
By Daniel A. Keener
It was super easy to install. One wire coming from the main battery, going into side A. One wire going from side B to the second battery, and a ground! I have a Power Bright PW1100-12 Power Inverter 1100 Watt 12 Volt DC To 110 Volt AC hooked up to the spare battery. The inverter has a led readout that shows amps left on the battery, and it verified that the relay was charging the second battery.By far the easiest setup for charging an extra battery!The unit itself feels very sturdy, and mounted very easily.There are break away tabs on the cover, so the wires can come out either to the front, or the sides.I would definitely recomend this unit!

5Perfect. Install it. Forget about it.
By Dano
This thing is perfect. Install a second battery, and you never have to worry about your starting battery running down from running stereo and lights while the motor is off.Every boat that anchors and uses lights or stereo should have one of these with a second battery. It would put the towing companies out of business.

5Easy quick and automatic
By Timo
Sure, you could save a couple of dollars with a few manual switches that you have to fiddle with. Not here. Plug and play. It could not be simpler. I like it!
