It is a Power Supply Module/Battery Charger Control Module, Input Voltage: DC 7~80V, ST processing chip, stable performance, high integration and durable. Automatic Power-off function and discharge protection can prolong battery life. Suitable for discharging protection of all kinds of batteries.
Set and debug the module before connecting to the load. Watch the indicator light, on means there’s input, off means no input.
Set Stop Voltage:
Long press on “-” button for five seconds to stop voltage value flashing, then press “+/-” button to set stop voltage value.
Pressing the “+” button once, the indicator light will be on and input starts. Pressing the “+” button again, the indicator light will be off and input stops.
Mandatory Input for five seconds:
Long press on “+” button for three seconds to enter mandatory mode. Five seconds later it will automatically come to normal mode(stop voltage in normal mode is lower than battery voltage and protected lines will be automatically cut off after five seconds of mandatory input)
When the new battery is initially used, the rated voltage is close to actual value. To determine stop voltage, user can use general voltage calculation method of battery to calculate reasonable discharge voltage value.
When this module is used on the old battery, the actual voltage value and the rated voltage value differ greatly. User needs to measure stop voltage value in actual use.
