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. On vehicles and boats, this charging source is almost always the vehicle alternator which is in turn powered by the engine. 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.

WHY USE THE 12V 70A CAMPER MOTORHOME INTELLIGENT SPLIT CHARGE CHARGER CHARGING VOLTAGE CONTROLLED KIT?

This Voltage sensitive split charging kit, or VSR, senses the voltage of the starter battery and close the contacts inside the relay at a pre-set threshold 13.3V. The contacts then open again at a pre-set lower threshold 12.8V. So when the alternator starts turning the voltage rises to around 14V at the starter battery terminals (assuming the battery is already well charged) and the relay will close to allow current through to charge the leisure battery. When the engine shuts off and the alternator stops turning, the voltage will gradually drop away at the starter battery terminals and the relay will open again, isolating the batteries once more.

Features 

  • Automatic operation
  • Simple to install (no need to modify factory-fitted electrical system - no warranty issues)
  • Dual sensing, meaning that they operate when sensing a voltage rise on either side of the relay. This means that the starter battery will also charge when the leisure battery is being charged by a mains battery charger.

 

 

Easy to install

There is no need to cut into any factory wiring that may void the manufacturer's warranty of your boat or vehicle.This type of split charge device is the most popular on the market for campervan conversions, 4x4s, smaller motorhomes etc. They are relatively simple to fit and reliable.
