Ask a Question
  • Should I keep battery plugged in during off season?


    Thanks for your question.  Torqeedo recommends storing the Power 24-3500 battery at a 50% SOC (state of charge).  If it will stored for an extended period then you will need to to check the battery every few months to make sure the battery SOC doesn't drop too much.  In general, lithium-ion batteries do not like to be stored either fully discharged or fully charged.
