Due to the small volume of smart watch, it will restrict the use of cell volume, a child watches price positioning, it is known, watches children smart positioning, the battery capacity is directly proportional to the size and volume, the smaller the volume, mean cell The lower capacity, the shorter the life, the greater the volume, the larger the battery capacity, battery life is long. Therefore, the smart watch, the battery life is a bottleneck, and that if there are products to the smaller capacity batteries, bring a longer life time? [1] The analysis of the current children's intelligence watch battery, positioning watches, basically using lithium battery technology, positioning the students watch what brand is good, but at this stage in the field of lithium batteries is still not much of a technological breakthrough that extends battery life means the volume increases, and as Smart Watch, the volume has been defined very limited, so the battery life it has become a bottleneck, who can bring longer battery life in a limited volume, who can become the market leader. Linktop Technology focuses on research more than a decade, has accumulated a wealth of successful experience in manufacturing and overseas markets, "Xiong Bang Bang" is the maturity and development of a child through intelligent positioning wristwatch, products both in the overseas market and domestic market, repercussions are relatively good. "Bang Bang Bear" delicate appearance, functional, green and safe, repair rate is very low, in the same types of goods in is a very high cost of the product.
