Just select the appropriate battery voltage, and the device does everything fully automatically until the completion of the charging cycle and maintenance charge of full batteries. With the Dino KRAFTPAKET battery, it can also be charged directly in the vehicle, eliminating the need for time-consuming removal of the vehicle batteries. The Dino power pack is suitable for all common 6V and 12V lead acid batteries (normal, AGM, gel, CaCa, maintenance-free, open). Special feature: even in 6V mode, the Dino KRAFTPAKET delivers a maximum charging current of 3A. Recommended battery capacities range from 6Ah to 100Ah, with trickle charge capabilities up to 160Ah. Two charging programs are available (6V and 12V), allowing for fully automatic charging in three steps: 1st constant current phase, 2nd constant voltage phase, and 3rd trickle charge phase.
