I Carried out a motorhome conversion last year, when putting in the electrics I fitted a Battery Charger to the leisure Battery but did'nt think to fit one to the engine Battery, so thats my next job. Appreciate any advise on a good one to fit.
The easiest way to achieve engine battery charging is to fit a Battery Master. Sorry, can't do links but just Google Battery Master and it will come up, available from Van Bitz.
I contacted the people who supplied the electric package for the conversion, only to be told that the charger I've got for my Leisure Battery, charges my engine battery as well.
