Spyder Posted January 17, 2023 Share Posted January 17, 2023 As the title suggests I’m wondering which would be the better option. I know the Vanbitz Battery Master keeps the vehicle battery topped up but does a Victron B2B do the same? if not can I have both fitted so that the B2B charges the leisure batteries and the BM keeps the vehicle battery topped when not moving?

Derek Uzzell Posted January 17, 2023 Share Posted January 17, 2023 The Victron B2B will charge the motorhome's starter and leisure batteries when the vehicle's engine is running. The Van Bitz Battery Master is a 'battery balancer' designed to trickle-charge the starter battery from the leisure battery when the latter's state of charge is above a certain voltage, and the motorhome's engine does not need to be running for this to happen. I noticed on the MHFun forum this 2022 discussion that may help. https://www.motorhomefun.co.uk/forum/threads/victron-b2b-and-vanbitz-battery-master-query.259640/ Link to comment Share on other sites More sharing options...

Klyne Posted January 17, 2023 Share Posted January 17, 2023 If it's any help I have had Battery Master's fitted to both my motorhomes. Thus far they have proved very effective. They are a fit and forget device so suits my limited technical skills😉 David Link to comment Share on other sites More sharing options...
