1.Common cathode design adopted.
2.LCD screen for displaying system working status and parameters.
3.Adjustable charge and discharge controlling parameter.
4.Boost Charge mode auto shifts on when the battery voltage is lower than boost charge return voltage.
5.Double temperature sensors design, inner sensor for inside temperature detection, and the outer independent sensor for detecting battery temperature which makes the battery temperature compensation more precise.
6.The controller can work out daily battery charging and discharging capacity which makes it more convenient to evaluate controllers and the whole system.
7.It possesses overcurrent protection when charging which can decrease the charging current so as to protect the charge circuit if it exceeds the rated current.
8.It will proceed equalizing charge every 30 days to protect the battery from vulcanizing.
9.Industrial grade chips and precision components adopted which can work under cold, hot and moist conditions.
10.Double MOS in series circuit adopted in charge circuit, PWM charging control to improve charge efficiency.
11.Power-fail protection for saving tech data which makes the system operation more reliable.
12.3 different load working modes: Pure light control, Lighting + Timing control, load open all time.
