Solar Panel Kit 25W 12V Solar Battery Trickle Charger Maintainer, Built-in Waterproof PMW Controller, Adjustable Mount Bracket for Car Automotive Boat Marine RV Trailer 12V Battery

Why should we maintain the battery?Generally, the battery continues to discharge even when it is not in use.This discharge consumes battery power and may damage the battery, thereby shorten its life.How to maintain the battery?The basic requirement for battery operation and maintenance is to keep the battery fully charged and not discharge.Our solar panels are designed for the daily maintenance of batteries, prevent damage to the 12V rechargeable battery due to excessive natural loss after long-term storage.Adjustable AngleThe adjustable joint ball make it possible to adjust the angle of solar panel to get as much as sunshine, increase 2%-3% more power.Solar CellThe installation location, sunlight intensity and light time are the main factors affecting the solar panel power generation.The stronger the sunlight, the better the charging effect.IP 65 WaterproofIP 65 waterproof design, withstand rain and snow, no worry to mount it outside, totally free maintenance.Pre-drilled HolesThese pre-drilled holes make installation a breeze! You can mount them on walls and roofs with ease.SpecificationMaximum Power: 25WMax. Voltage(Vmp): 18VOpen Circuit Voltage(Voc): 21.6 VShort circuit Current: 1.52AMax.
