Expansion: Tianneng Power 1 battery adopts "3+2+ 1" mode, and with the help of three patented technologies, two top-grade materials and a leading technology, four breakthroughs have been achieved: the battery cycle life has been increased by 30%, the total capacity has been increased by 33%, the continuous heavy current discharge capacity has been increased by 28%, and the low temperature capacity at -25 degrees has been increased by 65,438. Tianneng X7 battery adopts four-wire technology, continuous casting, continuous rolling, continuous drilling and continuous coating, and three stable batteries, which are more stable, suitable for any environment, not afraid of cold and hot winters, high density of poles, and improve the battery power performance by more than 30%. High-strength shell and high-density ABS shell are more acid-resistant, heat-resistant and impact-resistant.
