Larry,
Nobody has responded to your question: "How can this possibly be OK
for the 75AH battery? And why would a battery manufacturer say
this?" and like you, it goes against everything that I have assumed.
But to answer that first question: when I look at, I wonder why
Hi Allan,
Yep…At first my thought was with the batteries in parallel, they contribute
equally to the load. Upon further thinking, this could not be true because the
voltage must stay the same across all terminals during discharge. That can only
mean the larger battery provides more AH than the

Mixing of batteries of the same sise and brand, older vs new maybe
bepending on age and or abuse. Mixing of type or size of batteries, sorry i
dont really care if the manufacture says its ok, Its not for me. I have
tested batteries and BMS and even with everything right there can be an

Just when I thought I was becoming a battery guru, this came up: A customer
asked me if he could purchase two different size 12 volt Lifeline (Concorde)
AGM batteries and connect them in parallel. Of course I told him this was a bad
idea and all his parallel batteries should be same make, age,
the
time I installed them until I sold the house a few years later.

Even if it works for short term testing, I would imagine
Even if it works for short term testing, I would imagine long term
issues that would require more frequent equalization, and shorter cycle
life.
