The Lion Energy Ascent Expansion Battery is a deep cycle 100 Amp hour battery. It's maintenance free and enclosed in a heavy duty case. When plug into the Lion Energy Ascent 1500 Watt Generator it functions as if you had three internal batteries. By adding this Ascent Expansion Battery to the Ascent 1500 Watt Generator, you triple the battery power and power storage space.
When the generator is in use, the Expansion Battery is used first. If the Expansion Battery becomes empty the generator will immediately switch to the internal battery. The reverse happens when charging, the generator fills its battery first then charges the Expansion Battery.
