12VDC Car Battery Monitor kit

Reviewer: from Eastern Washington Stat, USA

This is a very clever, simple to build kit that does everything advertised! I have several in use, especially with my solar power system.
Oh, by the way. DO NOT REVERSE the polarity!! I inadvertently did this and INSTANT destruction!
