Battery monitoring/ balancing decisions

Time to make some decisions - there is too much info out there to digest it all!

I think that this paragraph was a bit of a revalation for me and cleared up what I had been starting to think

You want to watch the voltage under driving load, and not let them fall
below 10.5v per module (~136v for your pack of 13). Better would be to
monitor each individual module, and stop when any one of them falls below
10.5v.

To start with, if I am using 6 chargers, then I can just monitor each of the batteries (or sets of two batteries in parallel) and ensure that none goes below 10.5V.

If I do start to get problems, then I can consider some form of battery balancing then.

As for the parallel situation, I think that it would be good if I can avoid it but that may not be possible.

options for monitoring battereis seem to be the paktrakr or the dallas one wire chip
