The Victron Blue Power chargers are extremely user-friendly. The Blue Power charger can be used for charging both lead-acid as lithium-ion batteries. These chargers are 12V and can be fully adjustable to your use. In fact, this charger contains a night, and a low mode. In these modes, the charger will limit its usage to 50%, making the charger extremely quiet. The Victron Blue Power thinks ahead. When the battery is fully charged, the energy usage automatically drops to around 0.5 watt. Moreover, Victron Energy chargers spread 4 times less heat in comparison to other chargers. The Victron Blue Power also contains a storage mode. While not using your battery, it will not be discharged and thus the storage mode will be activated. The driving voltage will be limited to 2,2V per cel. This will result in a longer lifetime of your battery. Once a week, the voltage will be automatically raised to absorption level to recharge the battery.
