Review on Spartan Power Battery Multimeter 6 5V 100VDC by Dragan Nelson

The unit is a bit difficult to set up but I called support. Wow - that's an American phone number and an American support person. I had to wait a little bit, but he was great. Walked me through the menus, set it up and took the time to assist me once I had everything set up. The device works as advertised. This allows me to track the amps and watts being used by my AGM battery and track the current voltage with the % meter in the center of the screen.
