4.3.3 Battery Pack State of Health
State of health is a measure of the condition of the Battery Pack and its performance relative to
a new Battery Pack. It takes into account the maximum energy capacity available in addition to
other factors. The state of health of the Battery Pack, like all lithium-ion batteries, will gradually
degrade over time as a result of use.
State of health is shown as a percentage value, with 100% representing the state of health of a
fresh Battery Pack. The state of health of the Battery Pack(s) can be seen in the Mobile App.
4.3.4 Battery Pack Cumulative Energy Output
Cumulative energy output is the amount of energy that has been output by the Battery Pack
throughout its lifetime, measured in kilowatt-hours (kWh). It is a way to measure system lifetime
usage which accounts for the system power output, measured in kilowatts (kW), as well as
hours of operation. It is similar to an odometer in a car, but appropriate for outboard motors
which operate on different vessel types.
The cumulative energy output of the Battery Pack can be viewed in the Pure Watercraft Mobile
App.
4.3.5 Additional Battery Pack care recommendations
When operating the system, do not let the Battery Pack discharge to 0%.
