- Output Current: Rate 3A, Max 4A ( If more than 15W, please install the heat sink, this item do not include heat sink)
- Constant current range :0-4A (adjustable)
- Revolving light current: constant current value * (1% -100%), Revolving light current value Linkage with the constant current value, such as the constant current value is 3A, Revolving light current is set to constant current of 0.1 times (0.1 * 3A = 0.3A) when adjusted to the constant current value when the 2A, then Revolving light current is 0.2A (0.1 * 2A = 0.2A). Default 0.1 times
- Minimum voltage pressure: 2V
- Output power: natural cooling 15W, (if install heat sink can be 25W)

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.)
