I'm trying to get my bike back on the road after I replaced a set of cells on my 48v20ah slim line v2.5. I run it with BMC 600h.s. rear, a crstalyte 36-72v 40amp. controller. The battery was cutting out Ping had me solder the shunts to up the cut off on the BMS. it worked good till I went up a steep hill. O.K. These is where I replaced the cells and Ping sent me a 60amp. BMS. Put it all back together, charged it. It worked it the lights went off then it shut off. The no. 1 cell was 3.71v the rest around 3.82 to 3.84 except 4&5 where 3.88v. counting from the red wire on the BMS.I charged the new cell to 3.8v. It would cut out till I repluged it in a couple of times. Worked find around town. I charged it again a couple of times to help balance. I checked the cells 4&5 where racing between .88-6.25v off the charger. After a couple of charges I checked it and now cells 4&5 were O.K.,But cell 7 is between 3.58-6.25v and cell 8 is .90. If I put back on the charger it will balance to 3.83 to 3.82v off the charger with 61.4v. Then I would start it up No load the lights would start blinking then cut off. the pack is at 14.4v and 57.8v before the BMS. I know This mite be hard to fallow, But computers are new to me,and so is these E.V. bike. Maybe someone could HELP ! Just with the bike for NOW. Forget tring to help with the spelling. THANKS ??????
