I'm working with some Leaf battery modules. As I'm assembling battery packs, I'm trying to adjust their voltage so they will work with common Curtis and Alltrax controllers. Does any one know or, better yet, have experience pushing the upper voltage limit of these? Example: 8 Leaf modules in series have a working voltage of ~60V (~3.7 X 16 - each module is 2S). Is this too high for 48V rated Curtis or Alltrax controllers. Does the handheld Curtis programmer(Model 1313-4331, for example) go this high?
