The assurance of starting instantly, whatever your consumption at the stopover

The classic dilemma in a converted van: how to enjoy your equipment when stationary (lights, water pump, heating) without having that little voice asking whether the engine battery will hold out? This worry can spoil the pleasure of being autonomous. The CSB40-S automatic battery isolator is the simple, reliable and robust answer to this problem. Designed to be the infallible guardian of your starter battery, it provides you with fundamental security: that of being able to set off again at any time.

This battery separator is the essential and secure link in your electrical installation. Its role is devastatingly simple. As soon as you start your engine, it detects the alternator voltage and intelligently connects your auxiliary battery so that it recharges at the same time as the main battery.

You thus optimise every kilometre to fill up with energy. As soon as you switch off the ignition, it instantly isolates the two batteries. You can then use all your devices without ever drawing on the engine battery's reserve. Robust, easy to install and requiring no adjustment, the CSB40-S is the centrepiece for a reliable and durable electrical installation, guaranteeing you complete peace of mind at every stage of your adventure.
