If you want to see the current coming and going into your battery this unit will not do that.
Read the Q/A's. This is the response from the seller!
Question: does this meter count up the amp hrs used and then start subtracting them when charging begins. Giving you a running total
Answer: No. The meter can not measure reversed current. If the current is reversed, the meter will show 0.
