Back from Ottawa with the loot:
Seven of these will find themselves into the car this afternoon, hopefully. (Why 7 and not 8? I'll leave the best battery of the existing pack in the car for comparison purposes for a cycle or two.)
2 of the 16 are "weak" according to the previous owner, and were being supported with individual chargers. Fortunately Rick, who did the swap, drew a pack diagram, labelled the batteries, and noted voltages before he pulled them, and Sue confirmed the weak ones on the diagram at last night's EV meeting. So it won't be a guessing game.
