The first graph below shows the state-of-charge versus voltage at a 1C discharge rate for the ETX12 (representative of the ETX series batteries). - Page 14 ETX12 discharge curves at a 1C rate over a wide operating temperature range. Note: there is 20% decrease in Ah and discharge voltage at -30deg C as compared to 25 deg C. All the EarthX ETX series batteries exhibit similar discharge curve profiles.

Page 18: Charging
Failure to follow these instructions may result in damage to the battery! The ETX Lithium battery is shipped fully charged if ordered directly from EarthX, so try to start the vehicle without charging. If ordering from an authorized dealer, it is recommended you check the voltage first and if it is above 13.3V, continue to install and start vehicle. -
