DIY Arduino Load Bank Lipo Storage/Discharger Station

About: I love fly. Im a electronic, robotic and automation technician. I like drawing 3D parts.

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

1x - Arduino Uno R3 https://bit.ly/2tThBPl

1x - SSD Relay DC-DC (Im using 100A ssd) https://ebay.to/2uqL3NG

4x - High Power Load Resistor(Im using 3R 100W) https://bit.ly/2zLZ3GK

Resistors https://bit.ly/2LsCNDl

1x - 10k

6x - 220ohm

1x - 4S Lipo Balance Conector https://bit.ly/2NntAMY

1x - Cooler Fan https://bit.ly/2NrhiTP

1x - XT60 https://bit.ly/2LqGKIJ
