1. Thermistors.
2. Contactors.
3. Thick, good quality cables.
4. Inductive current sensor.
5. Controller with various repurposable components.
6. 125A fuse. (Not shown.)
These will come in handy for various projects.
I googled the current sensor for example, it uses a 5v supply and has a 2.5v output at 0A and deviates in both directions by 1v/100A measured.
Very practical!
