Due to the nature and type of chemistry, all batteries suffer from varying degrees of internal resistance, which restricts the flow of energy into and out of a battery. Battery design & construction, age and temperature also effect that energy flow.

The following graphs show this battery's flow charactaristics and were derived from manufacture supplied sources and other sources, and are theoretical calculations meant for evaluation & comparison purposes only. You should expect some variances due to a wide range of application & design variabilities encountered in real world use, compared to a controlled testing environment.

Run Time Minutes

Amount of time this battery can deliver a continous current until the battery reaches 100% DoD, or it drops to 8.0 volts.

The voltage for a fully charged lithium iron phosphate battery is +13.0V. A 100Amp (C/1) draw is the equivalent of +1300 watts of energy at 0% DoD. This battery will still deliver about 1260 watts at 80% DoD @ 77°F, but will have dropped to 800 watts at 100% DoD.
