Renault Trafic or Vauxhall Vivaro Battery to Battery Split Charger Charging Energy Combiner Kit
What is split charging?
Split charging is the term used to describe the simultaneous charging of the vehicle starter battery and the leisure battery (or batteries) from a common charging source. Modern split charge systems typically have a device that connects the starter and leisure batteries only when a charging source is operating, and electrically isolates them otherwise, ensuring that the use of one battery does not draw current from the other. It is important to ensure that the starter battery is isolated so the engine can always be started, but you also don't want the leisure battery to be accidentally drawn upon when starting the engine because dedicated leisure batteries are not designed for high current output over short periods of time and can be damaged.
Easy to install
This type of split charge device is the most popular on the market for campervan conversions on Renualt Trafic, Vauxhall Vivaro, Nissan NV300, Fiat Talento etc. They are relatively simple to fit and reliable.
