18650 lithium battery-LED advertising light boxes lithium battery group applications
An outdoor LED advertising light boxes:Advertising light boxes, also known as "light box posters" or "night out posters. For outdoor advertising light boxes, the application places located in the road, both sides of the street, as well as video (drama) hospital, exhibition (sales) will be the commercial downtown, railway stations, airports, docks, parks and other public places. Abroad called "semi-permanent" street art. New flexible light box changed the traditional light boxes daytime poor image, the text glyphs monotonous shortcoming with its lifelike image. Glyph display, day or night are bright colors, strong texture unique decorative effect.
Outdoor advertising light box battery backup requirements:

Outdoor advertising light boxes lithium battery protection function
Using imported Sanyo 18650 lithium batteries: lithium-ion batteries
The battery overcharge function: P + and P-between plus charger to charge the battery, voltage charge to 12.6 ± 0.05V (according to design) protection circuit operates off the charging path, overcharge protection
Battery over-discharge protection function: connected to the load between the P + and P-battery discharge protection circuit operates when the battery voltage drops to 9V ± 0.1V (according to design), off the discharge path, over discharge protection
Short circuit protection function: When the P + and P-short circuit protection circuit rapid action of 5-50uS, cut off the path to achieve short-circuit protection
Overcurrent protection function: When the B-end P-end voltage of (0.15 ± 0.02V) protection circuit rapid action of 5-26ms, cut off the path to achieve over-current protection
