Hi, we just bought an Lithium battery to replace our house Acid batt. We figure we cannot use our old Argo FET 100-2 to connect to our Lithium batt. We are told we should buy the Orion DC-DC. Does this mean that we no longer need the Argo FET 100-2?
Can we use only the Orion DC-DC between our Acid and our Lithium?
One dealer says that we need to pay for consultancy. Another dealer is suggesting other brands.
Is it so that Victron does not have a good solution? Sounds very strange to me!
Could you point me in the right direction at least?
Right now we have an alternator charging 2 acid batteries (house+starter) and we use the Argo. Works fine!
What are the upgrades that we need to do in order to replace the house battery with a lithium (that has a BMS built in)?
Does anyone know which device to put between the alternator and the lithium battery? And with or without the argo to charge the Starter as well?
According to may understanding 2 batteries (1 x Lead-Acid, 1 x LFP) charging is easy problem. Install Orion TR Smart DC DC Charger (probbably non-isolated in case of common negative). Instalation sheme is simple.
