Why NMC/LMO/LCO over LFP on OEM EVs? Due the cell cost. LFP base patents are still valid for few years while others are free game. Sometimes I feel they also wanted to make shitty solutions to prove EVs are no-go. You just got to love how Tesla is wiping floor with those arrogant a*#%¥£es. :)

I have seen very little evidence of such. Most people are still driving their conversions BMS or not. My vehicle has over 20,000 miles on it with no sign of capacity loss. Sent from my iPhone > On Aug 13, 2016, at 3:50 PM, Lee Hart wrote: > > paul dove via EV

Hi, I have china e-bike "Zapp" (www.erider.cn), 2,5 kW / 60V engine and 19s (40 Ah) LiFePO4, without BMS. Oryginal cells (from 2007) were made by Thundersky. After about a year of use, the 4 cells (from 19) were dead and I stop to use e-bike. Now I started to "repair" this e-bike. I order the
