VOTRONIC StandBy Charger Pro

Battery recharging & charge retention

Perhaps this situation sounds familiar to you: You are standing 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 the vehicle radio or vehicle 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. While all VOTRONIC mains chargers, solar charge controllers and combination chargers have a power-reduced auxiliary charging output in addition to the powerful main charging output, which supplies the starter battery with a defined trickle charge, many conventional devices unfortunately do not have this at all.
This can be remedied by a so-called stand-by charger.

• Charging technology at the highest level
• The battery is the central element of a vehicle's electrical system. It requires the greatest attention, maintenance and care and, above all, it must be charged correctly.

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. For this reason, the Standby Charger (item no. 3065 or 6065) is unfortunately not suitable for these batteries. The VOTRONIC StandBy Charger Pro, on the other hand, has an adjustable undervoltage limit at the input. Charging is interrupted if the voltage falls below this limit. This means that it can be operated on a modern lithium (LiFePO4) battery as a supply battery without any problems and without running the risk of draining it completely.

• Charging converter for recharging and charge retention of the starter battery
• 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
• Passive cooling without fan
• Two independent 12V control inputs:
• "EN" (enable), to activate
• "DIS" (disable) to deactivate
• Standby charger can thus be switched on externally via switch and switched off, for example, by D+ while driving
• 2 LEDs provide information about the operating status
• Safe to operate due to built-in overheating protection
• Dimensions (WxLxH): 105mm x 71mm x 25mm
• Weight: 92g
