The Qoltec Monolith 12 V / 20 A intelligent charger provides safe and efficient charging for LiFePO4, AGM, GEL, SLA and calcium batteries. Three-stage charging, active cooling, LED indication and comprehensive protection features help extend battery life and ensure reliable operation.
Intelligent three-stage charging
Three charging stages—BULK, BOOST and FLOAT—adjust the voltage and current to the battery's condition. The charger supports fast, complete and gentle charging without unnecessary energy losses.
Compatibility with multiple battery types
Select the appropriate mode for a LiFePO4, AGM, GEL or SLA battery. The clear control panel with buttons and LED indicators makes setup and operation monitoring easy.
Complete connection and safe operation
The charger is equipped with a power cable and red and black alligator clips for easy connection to the battery terminals. Built-in protection features contribute to safe charging.
The Qoltec Monolith intelligent charger is designed for 12 V LiFePO4, AGM, GEL, SLA and calcium batteries. The charging current of up to 20 A enables efficient energy replenishment, while intelligent control automatically adjusts the charging parameters to the battery's current condition.
Charging takes place in three automatic stages: BULK for fast charging to approximately 80% capacity, BOOST with a constant voltage of 14.1 to 14.8 V DC, and FLOAT for gentle completion and charge maintenance. LEDs clearly indicate the current charging progress.
Practical features for safe use:
- memory of the last selected mode and battery type,
- automatic active cooling during charging,
- automatic charging completion and sleep mode after charging is finished,
- protection against short circuits, reverse polarity, overcharging, overvoltage, overcurrent and overheating,
- durable design with corrosion protection,
- connection cables with clamps and an additional fuse included.
