Im migrating from 12v to 48. I have 4 12v 200ah litium battries. I just got a eg4 3000-48v all in one. I plan to get a eg4 48v battry asap. Once i do can i link then all together. Wire the 4 into a 48v and atrach it to the eg4 battry?
Should work assuming you use an inter-battery balancer/equalizer. You can put any number of 16s LFP batteries in parallel and they should share the current proportionally.
This might work, but it is not recommended as it could lead to having unbalanced battery cells
