It can charge the lithium battery use of multi crystalline solar circuit board, also work while charging, effectively solve the problem of charging in some areas. The product has a lithium battery protection board developed by the company, solar control circuit board. Under the sunlight,. 9 hours can be filled, 8ah 12 hours can be filled with, the product is lanyue technology first, to fill the market blank automatic charging. Product features: 1 solar charge, with 15 watts of solar panels, charging efficiency of 17%, the use of life 15-20 2charge current indicator: equipped with a charging current meter, charging visible 3 over charge protection, lithium batteries are equipped with protective board, charging end automatically stop, current to zero 4 portable and high life lithium battery, life 800 times above. 5 the volume of 16 liters of spray molding barrel, the overall weight of about 4 kg. 6can be equipped with adjustable supporting pole, solar panels must be in a certain angle conversion efficiency is the highest, through the support bar to adjust angle to achieve the best efficiency. Note: 1the solar panel must be placed in the sun before it can effectively charge, solar panels can not block (or part of the block), otherwise it can not charge 2the charging efficiency and the solar panel support angle, so it can be adjusted according to the current number of the right angle 3 the solar energy conversion efficiency and light intensity of the solar panels, the higher, the cloudy day is weak, the highest at noon, the morning and evening weak. 4equipped with a lithium battery of the spray quality is lighter, easy to tilt when placed, so the charge time can be poured into the barrel in the barrel to increase the stability of the bucket. 5avoid collision, hard damage Carton
