This BBWS battery to battery charger is a device typically installed between a starter battery (input) and a house / domestic / service battery (output). The BBWS is designed to charge up your 12V domestic / service / auxiliary battery from the power generated from your alternator, whilst your engine is running. It is designed to work with vehicles (old / new) and (boats old / new). As this device is 25A or 40A rated on the input, we recommend running from an alternator 60A+. This BB charges both lead acid style batteries and lithium batteries. The solar input is good for up to 32V and shall harvest 350W or 550W (model dependent). The BBWS shall simply get power from either solar or power generated from your alternator. It shall tap into where it can get the most power from.

  • The BBWS can operate from either a 12V or 24V input battery source and can charge a 12V output battery
  • The solar feed into the BBWS is 31VOC rated, harvesting up to 350W or 550W (dependent on model)
  • Waterproof, sealed aluminium construction
  • Four profiles :: AGM/Gel, Sealed Lead, Lithium, Calcium/Desulphation
  • Solar priority mode engages the unit exclusively as a solar regulator.
  • As the BBWS is pre-wired with sockets, it can be easily and quickly installed or disconnected, pending your needs.
  • IP68 rated
  • 97% efficiency
