Battery Internal Resistance: A Comprehensive Guide
Open-Circuit Voltage, often abbreviated as VOC, is the voltage of a battery when no load is connected to it. It''s the maximum voltage the battery can provide. However, once a load is connected, the voltage starts to drop due to the internal resistance. For instance, a typical AA alkaline cell might have a VOC of 1.5V.
Do I connect a load to charge controller or battery?
I agree with Jordi above. The SCC will disconnect the load when the battery reaches a certain discharge level. Connected directly to the battery might lead to a total discharge level. You can however connect directly to battery if your load current exceeds the max output rating of the SCC but you will have to manage it.
