Extended Life Support
An Extended Life Support (ELS) system is designed to double the operational time of a Battle Armor or Exoskeleton's life support system. This system allows suits to operate longer in hazardous atmospheres or in a vacuum, typically up to 24 hours. While lightweight, the system is bulky, limiting the amount of gear that can be carried. It was invented by the Star League in 2715 for use by their Nighthawk power armor and has since been adopted by many other suits.
An ELS system weighs 25kg and takes up one space slot. Only one Extended Life Support system may be mounted per suit. Inner Sphere Exoskeletons require at least one point of armor and an ELS system to operate in hazardous environments.
