VOTRONIC VCC 1212-30 CI – 12 V / 30 A Charging Booster
The VOTRONIC VCC 1212-30 CI is a high-performance 12 V to 12 V charge booster designed to optimally charge the vehicle battery while driving. It delivers a charging current of up to 30 A and is suitable for both traditional lead-acid batteries and LiFePO4 batteries.
Especially in modern Euro 6 vehicles with an intelligently controlled alternator, the charge booster ensures reliable and constant charging. It compensates for voltage fluctuations from the alternator as well as voltage losses over longer cable runs.
Thanks to various charging profiles, the on-board battery is charged quickly, gently, and fully.
Advantages
- Up to 30 A charging current
- Suitable for LiFePO4, AGM, gel, and lead-acid
- Ideal for vehicles with Euro 6 alternators
- Microprocessor-controlled, fully automatic charging
- Compensates for voltage fluctuations and line losses
- Automatic activation via D+, ignition, or voltage-controlled
- Temperature monitoring of the onboard battery
- LiFePO4 protection at low temperatures
- Charge maintenance for the starter battery when the onboard battery is being charged externally
- Suitable for use with EBL / EVS power modules
- Parallel operation with a solar system and grid charger is possible
- Compact and lightweight design
Suitable for LiFePO4
The VCC 1212-30 CI features special charging programs for 12-V LiFePO4 batteries. Together with the included temperature sensor, the battery temperature is monitored and the charging process is adjusted accordingly.
This makes the charge booster ideal for converting RVs and campers from lead-acid to LiFePO4 batteries.
Ideal for modern vehicles
In modern vehicles, the alternator’s voltage is regulated depending on operating conditions and is sometimes significantly reduced. As a result, a service battery often cannot be reliably charged using a conventional isolator relay.
The VCC 1212-30 CI generates a charging voltage suitable for the onboard battery, thereby enabling reliable charging while driving.
