Parallel Wiring Battle Born lithium batteries question

I am installing three Battle Born 100AH Lithium batteries in parrallel.
This was not my first choice, but they were the most rediliy available.

These batteries have an internal BMS but no external indication of any problem.

Normally, I would combine batteries with the positive and negative leads coming off different batteries at the ends of the parrallel string.
Like this:


However, in this case I am thinking of making up six identical cables and running a cable from each battery terminal to a positive or negative bus-bar.
My reasoning is that this would allow me to check the function of each battery with a clamp meter, also if there was a problem it would be easier to remove one battery.

Is there a reason not to do this ?
Am I just being parinoid ?

Re: Parallel Wiring Battle Born lithium batteries question

Probably answered my own question.

This article:
SmartGauge Electronics - Interconnecting multiple batteries to form one larger bank

Explains that in the case of three or more batteries in parrallel, the method I described is preferable.
