Votronic 20A-12V Battery Charger PB1220 SMT2B for Lead-Acid and Lithium Batteries

Designed for high-quality motorhomes, marine use, special vehicles and self-sufficient applications.

Votronic chargers are characterized by high operational reliability and readiness, thus representing the latest state of the art. Their high-quality charging technology, robust power electronics in conjunction with intelligent microprocessor control ensures precise adherence to charging voltages, currents, and times, thus extending battery life. A variety of different versions of the devices are available, so you can find the right charger for your application.

Votronic charging technology has been used for years in professional emergency vehicles such as fire brigades, ambulances, and coast guard! Quality Made in Germany!

All charging programs are applied by the charger for gentle full charging and then for battery maintenance charging, and if a temperature sensor is used, also with temperature compensation adapted to the battery type. The supply of connected consumers is also handled during charging, dimensioned so that during the I-phase (initial charging), no more than 50% flows to the consumers.

When batteries are full, almost the entire possible device charging current is available for consumers, without the batteries being discharged.

Further features at a glance:

15A main charge / 2A auxiliary charge
Charging programs Gel, AGM, Acid, LiFePO4 (No. 1, 2, 4 and Li) adjustable to battery type
Excellent charging technology
Adjustable Silent-Run function (night reduction)
Battery separation in case of power failure, overheating, malfunction
Charging voltages free of peaks, thus overcharging excluded
Fully automatic continuous operation for constant readiness of the batteries
Separate auxiliary charging output "S" for support and maintenance charging of the vehicle starter battery, max. 2A
Automatic battery regeneration during long periods of inactivity (twice a week)
Compensation of voltage losses on the charging cables for exact adherence to charging voltages
Built-in on-board network filter: Problem-free parallel operation with solar systems, generators, alternators, etc. on one battery.
Intelligent microprocessor control takes into account the simultaneous supply of consumers on the battery
Precise battery temperature compensation (temperature sensor required)
Power supply function: Enables the supply of consumers without a battery (e.g., battery change)

Selectable charging programs / charging curves:

"LiFePO4": Charging program specifically for Lithium batteries

Charging program adapted for Lithium-LiFePo4 batteries with their own BMS and prescribed or built-in protective circuitry. A special resting maintenance automatically keeps the LiFePO4 battery at a charge level of 50-80% which is beneficial for its lifespan when the vehicle is parked (seasonal operation) and also buffers 12V consumers as well as the vehicle starter battery. In addition, a regular Auto Wake Up function activates the battery cell balancing.

1. "Gel": Charging program for Gel batteries, characteristic curve IU1oU2oU3

Adapted for sealed, gas-tight gel/dryfit batteries with fixed electrolyte, which generally require a higher charging voltage level and longer U1 holding times to achieve short charging times with particularly high capacity storage and to avoid long-term battery "starvation". Among other things, perfectly suitable for our WATTSTUNDE Gel batteries.

2. "AGM": Charging program for AGM / Fleece batteries, characteristic curve IU1oU2oU3

Intended for charging sealed, gas-tight AGM (Absorbent-Glass-Mat) batteries and those in lead-fleece technology, which require a particularly high U1 level with coordinated holding times for full charging and then a moderate U2 level for maintenance charging (round cell and plate technology).

4. "UNIVERSAL": Charging program for Lead-Acid / Wet batteries, characteristic curve IU1oU2oU3

Universal program for charging and maintenance charging of acid batteries in vehicles (mixed mobile/stationary). With a medium U1 level, it still offers short charging times, a good charging factor and good acid mixing for open and closed, low-maintenance, maintenance-free standard, traction, lighting, solar and heavy-duty batteries, as well as AGM batteries with normal U1 level.
