Standby charger Votronic Pro

StandBy-Charger Pro
Charging converter for recharging and maintaining the charge of the starter battery

Perhaps this situation sounds familiar to you: You are on the beach in your camper and leave the car radio on for a long time or open the door frequently. Suddenly, the vehicle battery management system reports that the (starter) battery is running low and the radio switches off or the battery needs to be charged. This is often caused by high power consumption by, for example, the car radio or car control systems, which are active for a while every time the door is opened and consume a relatively large amount of power from the starter battery. Many simple standby chargers are not able to supply these high currents, which is why the starter battery is discharged despite their use. Modern lithium (LiFePO4) batteries have a significantly higher open-circuit voltage than starter batteries (lead, AGM). When using simple, unregulated and uncontrolled standby chargers, this leads to the complete discharge of the lithium supply battery. The VOTRONIC StandBy-Charger Pro has an adjustable undervoltage limit at the input. Charging is interrupted when the voltage falls below this limit. This means that, for the first time, they can now be operated on a modern lithium (LiFePO4) battery as a supply battery without running the risk of draining it completely.

• IU charging characteristic
• Adjustable end-of-charge voltage of 12.5 - 14.5 V
• Upward and downward conversion from input to output voltage possible
• Also works if the voltage of the battery to be supplied is lower than that of the battery to be charged
• Input-side adjustable switch-off threshold of 12 - 14 V prevents deep discharge of the battery connected on the input side
• Suitable for lead, gel, AGM and lithium (LiFePO4) batteries on both the input and output sides
• High output current of max. 8 A
