The Multi Battery System (MBS) which is used in many Walther Pro Lights, provides a choice for using several battery or accumulator types so that the customer can adapt the lamp flexibly to his needs and individual circumstances (for example, accumulators at home, where they can be recharged quickly, and batteries in the field). Moreover, rechargeable accumulators are environmentally compatible – a further step towards a sustainable way of life. And of course, the use of accumulators helps to prevent high operating costs.
