I keep looking for a small, cheap voltage meter to add to my battery pack(s). I hate those stupid LED gauges. The problem is all these 0-100 Volt DC meters use three wires. The third wire is to power the meter and requires somewhere between 5 and 30 volts. Now our friends in China are very clever. Why doesn't one of these geniuses add a couple of resistors to form a voltage divider so the darn things would only require a simple two wire connection
