Hello ebikers
The BMS of my battery pack is defective and need to be replaced. I own a 48volt (11.6ah ) battery pack made with Panasonic NCR18650PF, I use my pack on a 1000 Watts e-bike motor with a 30 amp controller that output 1000w constantly. After testing my pack I determined the BMS was the issue since one wire of the BMS was cut , this happened when I was put the pack in my battery case (Down Tube is also known as hailong). I have a second pack of 48 volts made of Samsung 18650 - 26F which work without problem with my e-bike. Soldering the cut wire did not solve the issue. I am currently looking for a BMS (30 amp continuous discharge current and 2.5 or 2.7-volt cell cut off voltage) I came across one BMS that is of interest to me on Aliexpress : https://www.aliexpress.com/item/High-quality-48V-13S-lithium-ion-battery-BMS-for-electric-bike-lithium-battery-with-30A-continuous/2025451657.html?spm=a2g0s.9042311.0.0.dHCjSx
However, I do not know if this BMS is going to work with the battery meter of my battery case. My currently broken BMS has P- (Negative discharge), C- (Negative discharge ) and B- (Connect to negative of battery). The new BMS on Aliexpress has the same port. I contacted the seller and I am still waiting on a reply. Will this BMS work with the battery meter of my down tube (hailong) battery case?
I am open to suggestion of different BMS as well. Thank in advance for your help
