Some time back I was informed that wiring batteries in parallel is the 'old way'. The new way is to tie them to a bus bar. I'm trying to get my head wrapped around the reason for using a bus bar in the following application. Space is tight. Cost and effort a consideration.
4-12v 100ah LifePO4 battery bank located under the entry steps: Two batteries can be loaded at a time, wired in parallel, wired forward for the next string, pushed to the rear and two more loaded, wired in parallel (max capacity - 4 batts). The two strings are tied together, connected to a 50A breaker that feeds a 12v distribution panel and a 2.5kw inverter/charger/ats w/300A breaker. Save charging for a different discussion.
Space is tight. I can mount a bus bar and run cables from batts to bar. The question is why? What am I buying myself by 'buying into' bus bar vs. the 'old way'?
Thanks in advance for your insights.
