So I start off my commute with a pretty long downhill portion (~500m?), and after first testing out my build yesterday, The option I was afraid of happened: braking was disabled after ~50m (over voltage protection kicked in).
I knew this was an option but was hoping maybe the charger would leave enough space in the batteries for the energy from the hill.
Right now I think the simplest option is charging to ~4.0v-4.1v per cell (I have a 6s5p pack), and maybe topping off at work if I need it.
Is there a charger I can program to select a voltage? I have a imax b6 (clone and original on loan from a friend), but they seem to only allow you to go down to 4.18v?
Any other chargers you can recommend? Any other options?
