SOK SK12V280H Charge Information:

  • Recommended Charge Current;    56 A
  • Maximum Charge Current:   120 A
  • Recommended Charge Voltage:    14.6 V
  • Maximum Batteries in Series:    4
  • Maximum Batteries in parallel:    10

  • Maximum Continuous Discharge Current:    200 A
  • Peak Discharge Current:    250 A (7.5 s ±2.5 s)
  • Recommended Low Voltage Disconnect:    10.4V



SK12V280H Size Information:

  • Terminal Type:    M8, 5/16 lugs
  • Weight:    48 lbs.
  • Dimension (L x W x H):    13.07*9.52*9.84inch
  • Case Material:    Black paint aluminum case



SK12V280H Temperature Information:

  • Discharge Temperature:    -4 to 140 ºF
  • Charge Temperature:    4 to 113 ºF (built-in heater pad)
  • Storage Temperature:    23 to 95 ºF



The SK12V280H built-in heat pad turns on under the following conditions:

  • Temperature is below 0° C (32°F)
  • A charger is connected and able to supply sufficient current to the pads
  • ≥ 4A for each 100Ah battery
  • ≥ 7A for each 206Ah battery


For example, on a cold evening after the temperature drops down to under 0°C (32°F), when charging the heated battery, the battery would go into low temperature protection. Charging the cells is disabled, and if the charger is able to supply a sufficient amount of current, the

heat pad would automatically turn on. When the battery temperature exceeds 5°C (41°F), the heat pad turns off, and charging the cells is re-enabled.



Certifications Information:

  • UL1973 & IEC62619 for battery cells.
