Normal Li-ion batteries offer 100W/8A output and suitable for most ENG cameras, but the Cine Cameras such as ALEXA require around 85W high draw which is too heavy for the normal Li-ion batteries: the battery life will be reduced if long time full draw powering. Moreover, if there’re monitor, lighting work together, and total power will be above 100W, and the normal batteries can not draw completely. Using S-8180A high-load battery, you can get MAX 140W/12A constant power output, which can drive more high power cameras, lightings and other equipments easily, and won’t reduce battery life during long time high power output.
