So I have acquired 3 Enersys PowerSafe SBS 190F AGM 190ah batteries to install in my Landrover to support a mobile/portable HF operation. At the moment I have one of these installed but I could put 2 or even all 3 on board. There is however a fair amount of inertia involved when moving these as they weight 132lb each. So the first question has to be how many batteries to put in the vehicle. The other question I have is how best to keep one or more of these charged. It's my (limited) understanding that the installed alternator probably provides too high a voltage to properly charge and maintain these for the long term. Is it possible to use a solar power controller fed by the alternator that would provide the right 'intelligent' charging for the proper maintenance of these batteries. Alternatively I do have an ICT intelligent charger which could be connected to shore power whenever the vehicle is parked in the driveway. I'd appreciate any advice or comments.
