I have a new MPPT Smartsolar 100V 20AMP controller, and want to stop charging my lithium battery below a certain temperature.
The temperature sensor will be connected to Lithium battery which is around 6Ft away from controller - I assume the wired sensor is 6ft long, and hence i dont need wireless.
I cant find the ASS000020000 Temperature Sensor Type C on a popular/cheaper ecommerce site such as Amazon. It is available on another site, but it is charging significantly more - for the sensor plus shipping.
Any suggestions?
