Features:Â
1. Identify *2V/*4V system voltage automatically.
2. Manual control for the load.
3. LCD indicates the working status of battery and load.
4. Double USB output charging for various electronic products. Max load current reach up to 1.2A.
5. LCD screen could show charge current, discharge current and capacity of the battery.
6. Adopting advanced ternary form charging algorithm, equalizing charge for battery once a week to prevent battery from imbalance and vulcanization effectively so that the battery service life will be extended.
7. External temperature sensor can realize high-precision temperature compensation
8. Various protections: Over charging protection, over discharging protection, over load, short circuit protection, reverse polarity protection, TVS lightning protection.

Methods for
setting
1. After installation, short press the to turn on or off the load
2. Slide the switch below the LCD screen to show controller's parameters.
3. When over load or short circuit, please cut off the load and ensure the load power satisfy the requirement before connecting again. Long press for 2 seconds to remove the load protection.
4. When over voltage or over discharge,load will be cut-off. It will be recovered after the system voltage return to normal.
