  • 12V chargers for lead acid batteries may work but will decrease performance and lifespan.

• Free Adapter:

  • Available for 24V, 36V, or 48V single batteries by request, at no additional cost.
  • Enables charging of 24V, 36V, or 48V batteries, or a bank of 12V + 24V or 36V batteries.

• Charger Rating:

  • Input: 100-120VAC, 50/60 Hz
  • Output: 14.4 volts, 40.0 amps (10 amps per bank/channel)

• Terminal Connections:

  • SAE connections for easy setup:
    • Install ring terminals using bolts on battery terminals.
    • Bolt black to the black terminal and red to the red terminal.
  • Connect the charger via the SAE plug when charging.
  • Indicator lights:
    • Red light: Charging.
    • Green light: Fully charged.

• Smart BMS Communication:

  • The charger can restart a Dakota Lithium BMS after:
    • A short circuit.
    • Excessive amp draw.
  • Connect the charger to initiate a restart.

• Lead Wire Lengths:
