Remember, we are talking over 250 cells here. Grinding through 250 heavy bus bars is nigh impossible, let alone welding nuts on top of the half dome ones, because it is over 500 nuts... In the mean time I have sacrified a 1/2" orphan socket that I had laying around and cut 5 tines on it, then tried to file them having a rounded inside as much as possible. It is not a great fit, but with a bit of convincing I can get the nuts to turn and thus taking the flooded NiCds out is the next step. They still seem to have 10% residual voltage after ~6 years neglect (no charging). Anybody have 20 planes that need a starter battery? Cor.
