Battery Capacity Meter User Manual
Introduction
The Powerwerx BVM-100 is a battery capacity meter that acts like a fuel gauge for your battery. The meter accurately measures your batteries state of charge (SOC) and voltage. This unit is compatible with most Lithium, Lead Acid, and Lithium Iron Phosphate batteries ranging from 12-60V. The BVM-100 can be easily programmed on the go and does not require any additional tools or devices to program out in the field.

Wiring Instructions
The meter is supplied with a 7in long pigtail to hook up to your battery. In some cases, this length will be too short so it is suggested to splice on any additional length that you might need. Connect the Black wire to your batteries Negative (-) terminal and connect the Red wire to your batteries Positive (+) terminal. Next, you will need to insert the 2 pin plug on the pigtail into the rear of the meter. The back of the display has a B(Battery Negative) and B+ (Battery Positive) marking indicating the correct polarity for installation. Make sure to pay attention to the orientation of the plug before inserting.

Meter Installation
The meter will require a rectangular knockout to insert and is held in place by pressure fitting tabs on each side. In most installations you will need to knockout an additional 1mm on each side for the tabs to fit in the knockout. Please refer to the knockout reference table below.

Battery Chemistry and Cell Count
With the meter powered off, press and hold the on the back and power on the meter. The display will show the current battery preset that is selected. You can use the and to scroll through the available menu options. When you have chosen the correct preset, press the button to return to main screen. At this point the meter is programmed for the correct battery chemistry and cell count, so it should be accurately measuring the current state of charge (SOC). When selecting a Lithium or LiFePO4 chemistry, the cell count refers to the number of cells
