Default Re: DC Voltmeter help

Bar graph meters are inaccurate. Assuming you have it wired correctly you should get voltage readings at full and 1 bar down then 2 bars down etc, so you have some real numbers to compare to this chart. A much better choice would have been a digital meter which reads actual pack voltage. As a service tech those things drove me. Seems no 2 read the same and they reset to 100% after every charge regardless of the pack total voltage.
After all voltage is what we want to measure.
