Been reading this thread and found the discussion quite
interesting, interesting enough to go looking. I found
this site selling L-ION batteries, charge protectors
and special L-ION chargers all at very reasonable prices.

One part of this discussion has been about not doing
it yourself, would making a battery out of these parts
constitute doing it yourself for someone reasonably
proficient and capable of taking care in assembly of
such a pack.

I fly a turbo and regaining about 6 kilo of battery
weight is attractive as I stand about 90 kilos ready
to fly.
