Hi there. I'm interested in the Orion-Tr Smart 12/25 isolated dc-dc 15a charger to charge my marine trolling motor battery but i wasnt sure if it would work with my set up. My starting battery is a 12v lead acid deep cycle marine battery and my trolling battery is a 24v 50ah lifepo4 lithium ion battery. My first question. Will it work with a lead acid 12v starting battery? Or should I upgrade my starting battery to agm for this system? The other question. Will it cause any harm to my lifepo4 litithum ion battery? I know my owners manual says to only use chargers compatible with lifepo4 specifically. So that is a concern of mine as well. Thanks in advance and thanks for you time!
