Multifunctional portable charger and intelligent maintenance device with Adaptive Boost technology CS FREE means freedom. The freedom to charge 12 V lead-acid and lithium-ion batteries anywhere. Even without mains power. As a portable charger, it recharges batteries with mains power - or with the power supplied by solar panel kits or secondary batteries. The CS FREE's revolutionary Adaptive Boost technology automatically analyzes the condition of the battery when the vehicle fails to start after simply plugging it in. It then determines the safest and quickest way to supply the battery with the energy required for a successful vehicle start within 15 minutes. In contrast to most so-called boosters, the CS FREE takes a differentiated and safe approach. The battery and the vehicle's electronics are therefore not damaged by indiscriminate charging. The CS FREE is also an intelligent maintenance device and a high-tech power bank that keeps the battery and electronics ready for use at all times. FunctionsCan be used for all 12 V lead-acid and lithium-ion batteriesSuitable for batteries in motorcycles, cars, leisure vehicles and motorhomesCountdown function with display of remaining charging timeCan safely remain permanently connected for intelligent maintenance chargingCan be charged and used with 12 V accessory socket, secondary battery or solar panelUSB-C and USB-A type outputs for charging devices such as laptops, smartphones and tabletsEasy to understand, easy to useNo mode selection - simply connect, because the CS FREE does the restComplete range of accessories for charging without mains power and practical storageNew ergonomic design with robust and durable housing.Easy to transport or mount on the wall with the optional CS Wall Mount

Marine & Camping Charger 24V 20A TBB Trident BP2420The BP-SERIES battery charger is an intelligent battery charger specially designed for charging all types of lead-acid batteries, i.e. wet, gel and AGM batteries. The DIP switch can be used to select the perfect charging characteristic for each type of battery. Thanks to the high-frequency technology used, the charger is compact and can also be installed or stored in small compartments or cabinets. The charger is insulated against direct and alternating current and is equipped with overvoltage protection, an automatic multi-stage charging function and many other safety functions that reduce the risk of electric shock and fire.The BP battery charger offers an unbeatable number of additional functions and protective devices in this price segment. These include, among othersAutomatic multi-stage charging curve The BP series battery charger has an automatic charging function with up to six stages and delivers nominal current for around 75% of the charging time. This function guarantees complete, fast and safe charging of your battery.Integrated timerWhen the charge drops to a certain nominal value or the charging time preset on the timer has expired, the BP series battery charger switches from absorption charging to trickle charging.Recovery chargeThe BP series battery charger is designed for a permanent connection to the battery. To prevent possible sulphation during long-term trickle charging, the charger automatically switches to recovery charging mode after 14 days. Simultaneous charging of several batteriesThe BP series battery charger is equipped with several DC connections (the 12A model with two, the 20A, 25A and 40A models with three connections) so that several batteries can be charged simultaneously. The total current (12 A, 20 A, 25 A or 40 A) depends on the model type. If several batteries are connected to the charger, the total current is divided between the individual batteries according to the degree of discharge.Insulated outputsThe outputs are electrically isolated from each other. This prevents current flows between the connections and a return current from the battery to the battery charger.Particularly low-noise designThe charger is particularly low-noise. If the charging current falls below a certain value, the charger's fan is switched off. If the temperature inside the device rises again, the fan is automatically switched on again.Simultaneous operation as charger and mains adapterThe intelligent BP series battery charger can be used simultaneously as a DC mains adapter and battery charger. The device software is programmed to prevent overcharging of the battery even under such circumstances.Protective coating of the circuit boardsTo protect against moisture and corrosion, the circuit boards installed in the BP series battery charger have a protective coating.Use as a power supply unitThe BP series battery charger can also be used as a power supply unit by setting the DIP switch accordingly. In this case, however, a constant voltage is supplied. In this mode, the device is not suitable for charging rechargeable batteries. The battery type and battery temperature are ignored in this mode. The temperature sensor does not initiate voltage equalization in this mode, but the overtemperature protection continues to function. In this mode, the charger can deliver net DC voltages of 13.5 V (12 V models) or 27 V (24 V models).Integrated protective functionsThe BP series battery charger has the following protective functions:1) Shutdown in the event of a short circuit at the output;2) Electronic protection against incorrect polarity;3) Shutdown if the battery voltage is too high;4) Power reduction if the charger temperature is too high, maintaining the temperature at a balanced level;5) Shutdown if the battery temperature is too high, automatic restart after sufficient cooling downAutomatic temperature compensationThe standard equipment of the BP series battery charger also includes a battery temperature sensor. If this sensor is connected to the battery, the charger can automatically regulate the charging current to the connected battery more precisely using appropriate temperature compensation.Operation at high ambient temperatures The BP series battery charger is designed for full-load operation at temperatures of up to 40 °CScope of delivery: Contents of the packagingIn addition to the charger, the packaging contains1) the operating instructions2) the temperature sensor
