1. Exclusive controller for Lithium Battery, which suit for ternary Lithium, Lithium iron battery, Lithium cobalt oxides battery, etc.
2. ”Normal working + Induction + Pre-dawn Working” three stages design, each stage could set working duration from 0h to 15hours, working power range from 0~100%.
3. Integrated controller and protection module of lithium battery together, which could protect both the whole battery and single battery.
4. Infrared induction and microwave induction optional.
5. Induction distance can be set.
6. Induction time delay can be set from 0s~150s.
7. Lithium battery can be activated automatically.
8. Flexible charging mode, on-off charge and PWM charge auto switch.
9. Lithium battery low-temperature charging protection. when the ambient temperature below 0℃, controller will stop low temperature charging for protecting the battery.
10. Intelligent working mode, the load power can be adjusted automatically according to the battery capacity, which can extend battery’s life.
11. Digital high precision constant-current control, the maximum efficiency can reach 96%.
12. Monitor the whole system and record the system status, which can keep 7 day's status records.
13. Infrared remote connection.
14. Overheat protection function, when the controller reaches a certain temperature, it will decrease or cut off the load.
15. Varies of system protections. Including the battery reverse connection, LED short circuit, open circuit protection and so on.
