Is it okay to use the Blue Smart IP67 to charge the main starter battery (lead acid) and then hook the Orion-Tr Smart to the starter battery to charge x2 100ah lithium 12v in series?
Essentially use the Blue Smart IP67 to keep the lead acid 12v topped off and when it is topped off use that battery with the Blue Smart IP67 to feed the Orion-Tr Smart to charge the lithium 24v system?
Looking at this as an alternative option to my other post if there isn't a solution.
