Battery voltage monitor.
I purchased this product a while ago and it works well. This product helps understand the state of the battery voltage without having to memorize the different voltage levels and where the battery state is at. I can tell with just a glance what the battery charge is. Also so far it seems reliable. The price of this unit was a little higher then I would like however it is work the cost for a simple display, and everyone in the family can read and understand this display. I like this product.
