However, 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.
The VOTRONIC StandBy-Charger Pro is used to automatically recharge and maintain the charge of, for example, the
starter battery in vehicles with two battery circuits. A possible connection can be made between the supply or body battery and the starter battery.
body battery and starter battery.
Only operation with two identical nominal battery voltages of 12 V/12 V is permitted. Mixed operation can lead to damage to the device and/or batteries.
Product features:
- Charge converter for recharging and charge retention of the starter battery
- IU charging characteristic
- Adjustable end-of-charge voltage of 12.5 - 14.5 V
- Conversion up and down 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
- Adjustable switch-off threshold of 12 - 14 V on the input side 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
