I have been running my converted Vectrix with 19 leaf modules for a year now, I installed without a BMS and had balance leads under the seat so I could manually balance when needed.
Unfortunately one cell started going low and eventually lost all charge and couldn't be revived.
I had one incidence when the bike ran low and I had to push it home but I assumed the LVC would protect it from over discharge particularly in the 38 cell setup.
I ended up up having to bridge the bad cell so I'm now running a 37 cell setup using the 36 cell firmware.
The capacity of the pack has dropped significantly and I get 16Ah from it at the most ( the range has dropped from 60miles mixed riding to 25Miles)
I have since read these cells can be damaged when charging in below freezing temperatures, ha s anyone experienced similar?
If so should we be installing a battery heating system when dong the conversions?
