MAINTENANCE
Sun Fun Kits Lithium Iron Phosphate batteries require minimal maintenance and do not need to have any
liquid added to them such as water (in the case of flooded lead acid) in order to keep charge. The only
maintenance required is to ensure that the state of charge of the battery is in a reasonable state depend-
ing on how it is being used. Please see the chart below:
State of Charge Recommended Use Notes
80-100%
Normal Use
For normal everyday use, keep your battery in this
range if you are using it at least once a month.
50%
Long term storage
Keep your battery in this state when you will not be
using it (for more than a month).
25-35%
Transport
For use in transport / maintenance, when your
battery is shipped to you, or if you need to return it,
it should be in this SOC.
