Creeky - time for a recap (from you) as you enjoy your harvest and bask in your fine accomplishment..

I feel a little responsible as I was one of those who encouraged you to "do this" when you were initially feeling a bit overwhelmed with the entire situation (5/29/2016).

What I read is that the initial time to do this was not at all what you expected and progress was far faster.

So, in retrospect . . .

What price is good to buy a Chevy Volt battery pack.

Where were you "lucky". For example all cells appear to work No damage to physical parts. Some of us may not have such luck.

How much time did you spend on disassembly and did you really need to do all that.

If you were to start again, what would you have concentrated on?

How many specialized tools were needed (lets not count voltmeter).

A lot of discussion was on BMS - but it seems like this may be unnecessary?

Safety - I know that this is "low" voltage, but sweaty hands/fingers on 48 V with a lot of amperage behind it can create a nasty burn!

Other issues import to recap on . . . .

Lastly, I infer that you have about 1 kW in panels. Might be helpful to describe more clearly your PV infrastructure. It is VERY clear why you replaced your old lead acid storage.

Thanks in advance as you now have singular knowledge that is very valuable.
