The Lithium Battery Power Set is the optimal combination for motorhomes or vans. Use the set to switch to lithium batteries or to equip your new vehicle with them right from the start. The combination of the individual components guarantees constantly full capacity and safe operation in all climate zones and all year long.The set is designed in such a way that it works as an independent system, but can also be connected in parallel to existing on-board electronics. It consists of a lithium RV battery MT Li 85, MT Li 105 or MT Li 120 in combination with a charger/booster combination and a battery computer (MT iQ Basic). All devices were developed by Büttner Dometic and are optimally geared to each other. The charger/booster combination unit (BCB 25/20) supplies the battery with charging current (20 A) if there is a 230 V mains supply and automatically switches to booster charging (25 A) while driving. In both charging situations, the device receives information directly from the lithium battery, so that it can optimally charge it. Additionally, the battery computer monitors the battery and displays battery capacity (in % and Ah), current consumption (A) and the remaining time inside the vehicle.The set includes a ready-to-plug-in installation cable set for the battery computer as well as a cable set for integrating the charger/booster combination unit into existing on-board electronics.

The fully automatic battery charging converter for LiFePO4 batteries in special vehicles, high-quality motorhomes and in on boats was developed according to the latest standards for charging supply batteries in lithium LiFePO4 technology while driving. In contrast to conventional cut-off relays, the charging converter automatically adapts the charging voltage to losses on the supply lines and fluctuating battery voltages. With a 24 V input voltage, it is even possible to charge the 12 V supply battery without an additional alternator.The charging converter guarantees the high quality of battery charging of the VOTRONIC chargers even while driving. The intelligent microprocessor charge control with "IU1oU2oU3" charging characteristics enables fast and gentle full charging and subsequent 100% charge retention of the batteries from any state of charge. At the same time, 12 V consumers connected in parallel can also be supplied and overcharging of the batteries is reliably prevented, even during extremely long journey times. The charging converters are characterised by their compact design, their low weight (high-frequency switch-mode technology) and their powerfully dimensioned power components. This ensures full charging power even with long charging cables and strong voltage fluctuations on the starter battery, for example in vehicles that comply with the Euro 6 standard.The charging voltage is free of peaks and regulated in such a way that the batteries cannot overcharge. Fully automatic operation via switching input (ignition, engine running, D+) and voltage control The automatic, adjustable power control enables priority charging of the starter battery by the alternator in the event of an overloaded vehicle network, thus ensuring immediate starting capability. No discharge (current 0.000 A) of the batteries during standby or when the charging converter is switched off Parallel and buffer operation: The battery continues to be charged or is kept fully charged if it is used at the same time. The charging converter automatically calculates and monitors the adjustment of the charging times. Monitoring-free charging: protection against overload, overheating, overvoltage, short circuit, polarity reversal at the output, malfunction and battery back-discharge through electronic cut-off up to complete disconnection of the charging converter and battery by means of built-in safety switches.Galvanic isolation between input and output: absolute separation of the battery circuits even in the event of a fault, important for 12 V/24 V mixed systems, prevents unwanted reverse discharges and suppresses interference in the vehicle electrical system. Charging cable compensation: voltage losses on the charging cables are automatically compensated for. Built-in on-board power supply filter: trouble-free parallel operation with solar systems, wind and petrol generators, mains chargers etc. on one battery Temperature monitoring and charge adjustment by battery temperature sensor (322/898), enables charging operation even outside the recommended LiFePO4 battery temperatures below 5 °C and above 35 °C.

This DC battery-to-battery charger ensures that the supply battery is always optimally charged while you are driving, so that you never arrive at your destination with an empty battery. Highly recommended for modern Euro 6 class vehicles with intelligent alternators. Also recommended for vehicles in which the cable cross-section is not sufficient to supply the connected devices.The supply battery is optimally charged while driving.Reliable solution for Euro 6 compliant vehiclesStable output voltage – suitable as permanent power supply for sensitive devicesAdvanced IUoU charging technology – adapts to all battery types, even lithium batteries with BMS (battery management system).
