Hi all!
I just put together a 13s8p battery using new vruzend caps that is being used with a generic "1000 watt" DD kit. I used recycled Panasonic NCR18650a cells from user tumich on this forum. The cells arrived with voltages between 3.4 and 4.1, so when I assembled I made sure the difference in voltages was no greater than .1 within each of the parallel groups. After wiring the BMS and charger both bought from vruzend.com, I plugged it in to charge. After charging, the cells remained out of balance with the lowest group being at 3.6 volts and the highest at 4.15 volts. I tried draining the battery some by riding the bike for 20 minutes then plugging it back in to see if this may help solve my issue but I haven't had much success. I guess I am just checking to see if the BMS is not working correctly or if I made a mistake by not balancing the cells beforehand or a different error.
Please let me know if you have any thoughts and thanks for reading!
