Pros
  • Charges in sub-freezing weather: a built-in heater warms the cells first
  • 206 Ah in one case replaces two 100Ah batteries and their interconnects
  • Lid comes off so the BMS and cells can be replaced instead of scrapping the battery
  • 7-year warranty
  • Steel case with handles and Bluetooth monitoring
Cons
  • At 50 lb it is a two-hand lift and needs a solid mount
  • IP50 metal case is not for bilges or open decks
  • SOK’s own pages disagree on continuous current (150 A vs 170 A) and on series use
