Shown above is a System 3 with 105-130 AH @ 20 Hr Rate & Up to 1530 CCA of Starting Power.

How do they work?

System 1. Simply a manual switch capable of carrying starting current, mounted on the negative terminal of the starting battery. During normal operation the vehicle runs on two batteries in parallel. The manual switch needs to be switched off when the auxiliary battery is being discharged and switched on when required to start the motor. If the battery is required to be charged quickly simply turn the switch to the off position. The battery will receive the full regulated charge from the alternator. After a couple of hours running or when at destination turn the switch to on.

System 2. A large heavy duty relay mounted between the positive of the starting battery and the positive of the auxiliary battery. We use 90-180 amp. Relays with 6mm cable and two 50-100amp fuses depending on the alternator capacity. This is powered by ignition so charges in parallel when the ignition is on and isolates the auxiliary battery when the ignition is off. All accessories must be wired to the auxiliary battery. This is commonly used with an “Anderson” type connector for trailers and caravans.

System 3. This is System 1 made electric powered. An electric switch capable of carrying starting current, mounted on the negative terminal of the starting battery. During normal operation the vehicle runs on two batteries in parallel. The switch is powered from the ignition so turns on when driving and charging and off when stopped . If the battery is required to be charged quickly simply turn the boost switch on the dash to the boost position. The battery will receive the full regulated charge from the alternator. After a couple of hours running or when at destination turn the boost switch off. If you forget the starting battery can’t lose charge.

System 4 is an electronic kit that performs similarly to system 2 with a led readout and a limit of 100amps.

System 5. This System is an electronic system developed by “Rotronics” recognized as one of the best systems developed over many years. Unlike many similar systems this one, like systems 1,3 & 6 allows the alternator to sense the state of charge of the auxiliary battery.

System 6.This system consists of An electric switch capable of carrying starting current, mounted on the negative terminal of the starting battery. During normal operation the vehicle runs on two batteries in parallel. The switch is powered from the ignition so turns on when driving and charging and off when stopped . If the battery is required to be charged quickly simply switch the boost switch on the dash to boost, the battery will receive the full regulated charge from the alternator. Switch the boost switch to off and the charging reverts to chargin in parallel unless the boost switch is agian pressed. If the boost switch is inadvertantly left on the vehicle simply operates on the auxilary battery with ther starting battery remaining charged.

System 7. This system consist on an electric switch capable of carrying strting current, mounted on the negative terminal of the starting battery. During normal operation the vehicle runs on two batteries in parallel. The switch is powered from the ignition so turns on when driving and charging and off when stopped. If the battery is required to be charged quickly simply push the boost switch on the dash, the battery will recieve the full regulated charge from the alternator. When the ignition is next turned off the charging reverts to charging in parallel unless the boost button is agian pressed.

Below is an example of how compactly the total system can be fitted giving up to 130AH & 925CCA Starting Power, to a HSE Range Rover.
