The battery control boosters from BÜTTNER ELEKTRONIK are the ultimate 3-in-1 solution for optimum charging of your on-board battery/batteries. They are simply installed in parallel with the existing charging technology, but can also be used as a stand-alone charging center. Depending on the selected power class, the MT BCB charges the batteries in parallel on the 230 V mains and during the journey with the booster function as required, but always with the latest IUoU characteristic curve. Voltage losses are fully compensated. The battery type is adjustable (liquid acid/gel/AGM/LiFePO4). With the MT BCB 30, MT BCB 40 and MT BCB 60, the charging power can also be reduced if required. All devices are equipped with a battery temperature sensor and have a long-term charging program with integrated pulser function to prevent harmful sulphation.
Simple installation: The MT BCB 25/20 comes with a cable set with a high-load relay
(80 A) is included. This makes it easy to install with an existing electrical control center (EBL, CBE). If the MT BCB 30/30/20 is to be integrated into vehicles with EBL, we recommend ordering the "EBL high-load relay with installation kit" separately. Note: The more powerful BCB devices are not suitable for vehicles with EBL.
