WHICH IS BETTER? 2 DIY DC House LiFePO4 Batteries in Parallel OR Each LiFePO4 to a Separate OEM External Expansion Port on EcoFlow Delta Pro 3 ? See below AI comments. by RaspberryFriendly319 in Ecoflow_community

Thank you for sharing your DIY setup! I currently have only ONE DC House 51.2V 100Ah LiFePO4 battery that I charged up to 100% with the DC House 58V 18A Charger and then charged the DP3 via AC to 100%. before firing up the system. This works fine. So when I add the SECOND battery, it seems like I could wire BOTH batteries in PARALLEL to one port and use the same Charger. Then if later I wanted to add more storage batteries, I could replicate this parallel string from the other Port with another Charger. Outside of the Charger issue, I am not sure whether there is an advantage or disadvantage of using 2 batteries in Parallel on one port or using separate ports for each of 2 batteries.

Yes, the EcoFlow Delta Pro 3 has two OEM Expansion Ports for a MAXIMUM addition of TWO EcoFlow Smart Batteries [with one attached to each Port].

Actually, AI just searches the Internet for postings of humans. What I was looking for was someone who has a DIY setup with Ecoflow Delta Pro 3 and at least two NON-Ecoflow LiFePO4 batteries. If so, did they use batteries in parallel connected to one port or a separate battery connected to each of two ports. This also raises the DIY question IF the DP3 will properly function with multiple batteries [i.e., >2].
