Victron Blue Smart 10A Charger w/Bluetooth

Your battery is charged, smartly to perfect condition.  The seven-step charging algorithm gets the best out of your battery. The charger gives the battery the power it needs, maintains its health, ensures better performance… and a longer life.  Unlike other brands, the Blue Smart IP65 Charger will attempt to recharge a deeply-discharged battery by force-feeding it with a low current. Normal charging will then be resumed as soon as there is sufficient voltage across the battery terminals.
