Battery Charging method:
1. Make sure the recharge battery float voltage and charge current, input voltage of the module.
2. adjust constant voltage regulator, the output voltage about 5V.
3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined charge current value;
4. Adjust Constant regulator allows Output voltage reaches the float voltage;
5. connected to the battery, try charging.
(1,2,3,4 step input connect power, output do not connect battery.)
LED constant current driver Usage:
1. Make sure LED current and the maximum operating voltage;
