I measured the Prius with smart key parasitic draw at 13mA. Still can't believe I killed the battery. By my calculation, I was drawing just 5.6 amps for those 30min. Should have been no problem for my 4.2 Ah battery, but then again it may not have been fully charged to begin with.

I'll probably go with the 20Ah prismatic cells for $35 each. Keeping the system modular is important to me so that a single failed cell doesn't brick the whole battery. The larger capacity should be a good buffer and handle abuse better.
