  • Multistage Charging: Fully automatic multistage battery charger with the ability to charge 3 separate battery banks.
  • Separate Battery Banks: Isolated charging design where battery bank one is separate from battery banks two and three.
  • Programmable: Battery bank 1 can be programmed with a different charge algorithm over banks 2 and 3.
  • Current Control: User adjustable current output (e.g. Dial the 60amp unit back to run off a 1kVA generator).
  • Smart Charging: The ePOWER 40A battery charger will regulate its output based on the loads connected to your battery banks.
  • Wide AC Input Range: Operates on both 110V / 60Hz and 240V / 50Hz.
  • LED Display: Easy to use “set and select” menu along with scrolling charger status.
  • Silent Mode: Disables the cooling fan for total silent operation at night or whenever required. Activation reduces charge output by half and locks out a fan for 12 hours.
  • Temperature Sensor: Battery temperature sensor included with 3-meter cable.
