From January to September, the company achieved operating income of 1.142 billion yuan, an increase of 39.08% over the same period of last year, mainly due to the increase in operating income of LED devices and components.
In 2014, the LED industry developed rapidly and the company's sales revenue increased. It is estimated that the net profit for the year will be 136 million yuan to 169 million yuan, an increase of 2-5 percent year-on-year.
As LCD display in YFJ company that we usually use it to military grade battery ,especially Lithium-ion batteries ,for these battery applications ,we have obvious advantage is that we focus more on shor circuit protection which we follow the US military standard.
Short circuit protection:The following test shall be performed. Charge batteriesas specified in ; use of 4.6.3 is permitted. Measure and record the OCV. Short each battery across all the positive and negative terminals with a total external resistance not greater than 50 milliohms. After one hour remove the short from across the terminals. Measure and record the OCV. Stabilize batteries at the normal conditions of 4.3.1 for not less than 2 hours. Chargebatteries in accordance with 4.6; use of 4.6.3 is permitted. Stabilize batteries at normal conditions for not less than 2 hours, then discharge the battery in accordance with 4.7.2.3. The battery shall meet the requirements of 3.7.2.3.
