![]() There are a lot of different strip shapes for this one pack. I think someone wanted an excuse to play with their shiny new custom nickel strip cutter, though. The pack is 4P battery strings, connected together in an interesting manner, with a lot of custom cut nickel strip and additional wires to bridge things to the next set of 11 cells where needed. It’s pretty clear what they’ve done at this point. Not for long! A bunch of chipping away of brittle plastic, and I’ve got… this. The positive end is covered with some black plastic insulation. This pack is dead, Jim_._ It’s not even nailed to the perch. The bulk pack voltage is a whopping 0.421v. ![]() Read on to join me for a lot of battery pack photos! Now I’m going to dive into the corroded mess and see if I can figure out what’s going on. To recap: A battery pack, bound together by a lot of adhesive, difficult to get apart, and I didn’t feel like pulling the actual battery pack apart after I got it out and discovered it was a corroded mess. If you missed part 1 of the Trek Valencia Ride+ battery pack teardown, you should go read that first.
