DIY Arduino Load Bank Lipo Storage/Discharger Station




Introduction: DIY Arduino Load Bank Lipo Storage/Discharger Station

Im a electronic, robotic and automation technician. I love DIY. Im a advanced 3d printer user if y…

Sometimes you charge your lipos but didn't flew, so you need storage the lipos.
I found in the flite test website one simple project, so my project basically its a remix.

My changes:

Added a SSD relay;

More Load resistor;

Cooler fan;

XT60 and balance connectors;

Small change in the code for better storage voltage value.

Step 1: Material

Step 2: Circuit Diagram

Step 3: Building

Position all components in your own box.

Put the load resistors into the dissipator.

Wiring the leds and resistors to arduino.

Solder the 10K resistor to balance connector.

Wiring all wires from balance connector to arduino.

Step 4: Arduino Code

Step 5: Video

Thanks for watching.

Any question, please comment.

Step 6: Original Project From Flite Test

    Changed to include comments and added a switch to change between a target voltage of 11.1v (storage level) and 10.0v (discharge level)
    Diagram as shown has the fan running the whole time the battery is plugged in.
    Changed the wiring to suit(stepdown unit connects to green wire instead of the red) and did away with the stepdown unit as I will use max 3 cells.
    Also changed wiring to accommodate a slightly different V/A meter which has only two wires for the current .
    Thin Blk to negative, thin Red and Yellow together on input positive terminal.

    Badly written code (has no comments)


    Question 2 years ago on Step 4

    So to use this for a 2s, all I would need to change as far as code, is the "target voltage"?
