The battery guardian module M102A is a highly advanced charge controller specifically designed for the simultaneous charging of two lead-acid batteries with a nominal voltage of 6 to 24 V. This device allows for efficient distribution of the charging current, prioritizing the charging of a depleted battery while keeping the other battery, which is needed for engine starting, fully charged. With a maximum charging current of 10 A (20 A with cooling), the M102A is ideal for applications in motorhomes, weekend houses, or other mobile power supply systems. The integrated balancing current of approximately 0.005 A between the batteries ensures that voltage control is maintained by any solar controller that may be connected upstream. This makes the M102A a reliable solution for anyone needing safe and effective battery charge management.
