I now have a couple of 7Ah SLA batteries for the portable nodes. These will not last as long as the group 27 batteries but will be more portable. These batteries should last about a day before needing to be recharged. I need to have a field charger or extra batteries to have charged and replace with the discharged ones. I would like to add a solar panel that would keep the node charged and running. It would be nice if it was small enough to still be portable.
