Votronic Standby Charger Pro

Intelligent charge retention of the starter battery

Have you ever experienced this?

You leave the radio on in the camper or open the door frequently and suddenly the vehicle's battery management system reports a problem. The reason for this is the frequently high power consumption by the radio or the vehicle control systems, which consume a relatively large amount of power from the starter battery every time the door is opened.

The Standby Charger Pro, which automatically maintains the starter battery charge, provides a remedy. The device can be easily retrofitted without changing the existing wiring and, unlike simple, unregulated standby chargers, is also suitable for modern lithium (LiFePO4) supply batteries thanks to an adjustable undervoltage limit.
