Hi All,

Just some thoughts on the following configurations. I have kit on the way (holders, BMS) that I can configure in the following 3 configurations, and was wondering on thoughts?

I'm bucking the voltage down to 12VDC, as this is basically a 12V battery backup. So keeping close to this voltage is desirable for efficiency reasons.

I know the names of these packs are incorrect, but I just don't have time to change the image right now, will edit post with the correct names later today.

Has anyone any thoughts in this? I heard from someone who knows the basics that over 8 in parrallel is a bad idea due to the difference between cells going up exponentially...
