If you have recently purchased a Battery Percentage Indicator you may have found that the percent reading that is shown isn't accurate. That is because the indicator doesn't know what type of battery you are using with it. Luckily it is quite simple to set up.
Step 1: Connect The Wires
Plug in the 2 pin wire connector into the back of the indicator.
Step 2: Check for Inaccurate Reading
Supply power to the indicator with your battery (You want to tap right into the main + and - leads of your battery). You may see that the indicator shows 100% even if the battery isn't fully charged. Disconnect from power once you check.
Step 3: Enter Settings Menu
To get into the settings menu hold down the settings button while indicator is disconnected from power.
While holding the settings button, reconnect to power. When it turns on you should see a new screen.
Step 4: Set Battery Type
Now that you are loaded into the menu you can release the settings button. Click the settings button again to change the letter (type of battery). Change the letter to "L" for lithium.
Step 5: Tell The Indicator How Many Cells You Are Using
The indicator doesn't know what your desired voltage is until you tell it. Click the refresh button to jump over to the number side. Keep clicking the refresh button to cycle through the different options. If you are using a 6s battery you'll want to select 6, 10s battery users should select 10, etc. The number of cells you have parallel doesn't matter.
In our case we are using a 10s battery so we stop when the screen reads "10".
Step 6: Save Settings
Disconnect power to save your settings. Next time you connect power to the indicator the proper percentage will be shown.
Step 7: Finish Installation
Continue with the installation of the LCD screen into your enclosure and the wiring to your battery.
There are a few other preferences available to choose from. Using the 2 buttons, you can cycle the screen into a mode where you choose how the screen reacts with power and back light. You'll see the battery logo change "Capacity levels" indicating a unique mode (back light off, push button for quick preview, etc). In our opinion, we prefer the default mode.
That's it! Your Battery Percentage Indicator should be working like normal.
