CBE CB522-LT Lithium Compatible Battery Charger

The new CB522-LT switching battery charger expressly dedicated to lithium batteries CB522-LT is an evolution of the CB500 series and designed for users seeking a high-performance system expressly dedicated to this innovative type of batteries. It has a single charging line specifically for lithium batteries with charging times and values optimised for this technology. In order to obtain an algorithm that maintains charging performance across different types of lithium batteries on the market, CBE has conducted extensive research and studied the systems made by major European manufacturers.

The new CB522-LT battery charger fills a niche so far not covered and actually more and more on demand by motorhome manufacturers, however, although our new battery charger offers an ideal recharging line for this type of product, I must emphasise that traditional CBE battery chargers can also be used with lithium batteries

The CB522/3 can also be suitable for lithium batteries using the charging line that is closest to the voltage values indicated by the battery manufacturer from the available three.  

The CB522-LT features overheating protection, plus the 12V outputs are protected against short circuits and polarity inversion.

Automatic charging system takes place in four phases.

·       Phase 1: Bulk – The battery is charged with maximum current until the end-of-charge voltage is reached.

·       Phase 2: Absorption – Battery charging is completed with constant end-of-charge voltage for a maximum time of 1h (or 30 minutes with I<5A).

·       Phase 3: Float – Maintenance charging at a constant voltage of 13.5V for a maximum time of 240 hours. The cycle is resumed from the bulk phase if battery voltage drops below 12.7V after a high load has been switched on.

·       Phase 4: Refresh – The battery is charged to the voltage of 14.5V for a maximum time of 30 minutes (or up to I<5A). Afterwards, the charge restarts from the float phase.
