Review on ⚡️ Battery Charge Controller with Digital Display & Protection Switch - 12V, 24V, 36V, 48V Battery by Kevin Ilango
Taking into account the current draw of the relay to the battery when idling and charging
In my experience I use a 9 V (6F22) lithium battery with a capacity of 600 mAh and a charge/ Discharge rate of 200mAh. - When the switch is on, the current consumption of the relay is 200 mA. So if your power supply current is limited to 300mA, the battery will only charge at 100mA. Therefore, increase the power supply current setting. - When the switch is off, the current draw of the relay is about 15-20mA, which will drain the battery if left unattended.
Pros
- Easy to read control panel
Cons
- You could also have chosen a newer model
