"How to Correctly Interconnect Multiple Batteries to Form One Larger Bank"
Two things I have noticed in my (more than) 20 years in this business are that:-
A. Many "specialists" simply tell you..... "do it this way, this is the correct way" without ever showing why they consider it to be the correct way, and often it isn't, which is perhaps why they couldn't show you why it is(!)
B. Some things have been done for so long, in a certain manner, that it seems they must be the best way of doing it. Otherwise why hasn't another method appeared?
Here at SmartGauge Electronics we always show you why one method is better. We don't expect you to take our word for it. We will happily use practical examples, theory, maths or whatever else it takes to show the results of various ways of doing things.
Interconnecting multiple batteries to form one larger bank is one case in point. Though in this case, newer methods have emerged over the years. Unfortunately they still aren't perfect.
Here is a diagram showing the old way of interconnecting 4 batteries to form one larger bank. This is a method that we still see in many installations.
