The main advantages include :
1. High power output and continuous discharge capacity : The Ewatt 21700 battery supports 36C ultra-high current second-level pulse discharge, achieving a new high power output, which can meet the output stability and anti-decay performance of industrial tools under extreme load. In addition, IT supports 40A continuous discharge for 7.5 minutes, which is 150% higher than the traditional 21700 battery, effectively ensuring stable output of the tool under high intensity operation ;
2. High energy density : The energy density of Ewatt 21700 battery reaches 273Wh/kg, the energy of a single cell reaches 18Wh, which is 20% higher than that of traditional 21700 battery, effectively solving the energy density bottleneck problem of power tools;
3. Fast charging technology : The Ewatt 21700 battery can charge 80% in 9 minutes, save 70% of charging time, reduce downtime and wait, and improve continuous construction efficiency ;
4. Long cycle life : The Ewatt 21700 battery has an extremely long cycle life of over 1000 times, professional-grade durability, delivering an ultra-high cost-performance experience with superior performance and ultimate reliability ;
5. All-tab technology : The Ewatt 21700 battery uses all-tab technology, through three-dimensional innovation of “material – structure – process”, achieving a 100% increase in power, a 60% increase in cycle, a 60% decrease in internal resistance, and a 60% decrease in temperature rise, empowering the development of the tool industry and promoting the lightweighting of power tools and the electrification of garden tools ;
6. High-rate discharge capacity : The capacity of the Ewatt 21700 battery remains at a high level even in a high-rate discharge of 1C, which is very important for high-power devices ;
7. Low resistance and high efficiency : The internal resistance of the Ewatt 21700 battery is relatively low, especially in a very low range when fully charged and empty, which means it can use electrical energy more effectively and reduce energy loss ;
8. Good heat dissipation performance : The all-tab design helps the battery dissipate heat more effectively, avoids overheating problems, and improves battery safety and stability .
