12v Battery to Battery DC-DC) Chargers

Battery to battery (B2B) chargers, also known as DC-DC chargers, are now the only option we recommend to charge a deep cycle leisure battery while you are driving. Suitable for all modern vehicles with stop start, smart alternators or ECU controlled charging systems.

B2B chargers are also recommended for older vehicles wanting a high quality charging system giving you a much faster charge and higher capacity than a standard split charge system using a relay will achieve.
