Notes on Tables
1.Nominal input current (considered continuous) is based on
2.Recommended bypass external overcurrent protection is based on 125% overload capacity for 10 minutes.
3.All recommended external overcurrent protections are based on 80% rated breakers.
4.Nominal battery voltage is shown at 2.0 volts / cell.
