Features:
The design of IP68 level and aluminum shell helps effectively prevent erosion
LED numeric display and waterproof keys are easy to use
An upgraded 3-stage PWM charging algorithm applies an equalizing charge to the battery every week, effectively preventing the battery from non-equalization and sulfuration and therefore extending the battery's service life
Up to 5 load working modes facilitate the product's application to different types of road lamps and monitoring devices
Charging program options are available for sealed, GEL and flooded lead-acid batteries and ternary-material lithium and lithium iron phosphate batteries
An external temperature sensor helps deliver high-precision temperature compensation
Parameter settings of power-down saving functions eliminate the trouble of repeated settings, making operation easy and convenient
