12V 30A Smart Battery charger for RV boat gel lithium sealed battery

B2B Operation :mobile operation from dynamo and starter battery (Battery to Battery):
it refers to charging the main battery through dynamo and starter battery, .If it is not used in the Vehicle , you can also use
one battery (12V) to charge another
1. .The efficient charging converter (booster) allows full charging of the board battery during
2. . It increases/reduces the voltage to the level, which is required for precise charging of the board battery with the optimum
characteristic line of
3. .The simultaneously supplied 12 V consumers are protected against overvoltage and voltage


Solar Operation
1. . The controller can improve the charging efficiency of the solar panel by 10-30% through MPP technology ( automatically
calculating the maximum power yield), effectively shortening the chargingtime
2. Thecontroller can charge the main battery according to the specified current by boosting or stepping down to ensure that the
main battery is charged according to the standard charging curve
3. Auxiliarycharging for support charging and trickle charging of the vehicle's starter battery in case of extended standstill
