Got dead lithium battery?   This jump starter will reactivate nearly all 48V LiFePo batteries.  When BMS detects over discharge, the battery will self-disconnect from solar inverter and charge controller.  The only way to force a restart is the apply an external charge directly to battery terminals.  When the battery is awakened, the normal solar charge cycle will start.


  • Supplies 3A at 48VDC into battery (144W)
  • Plugs directly into 120v wall outlet(or generator) with less than 2-Amp ac draw
  • Alligator clips for direct connect to 48V battery terminals
  • Internal protection prevents reverse flow out of battery
  • Typically requires only a momentary connection to awaken battery
