DIY Arduino Load Bank Lipo Storage/Discharger Station

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.

Material:
1x Arduino Uno R3
