Hi
I wonder if anyone may help me here.
I have recently replaced some cells in my e-bike battery. The cells are all the same. LG MJ1's
I did buy them in separate batches .. they look identical. I made the battery pack and replaced the BMS which was broken.
Now I have changed the battery just like I normally would, all of the new cells are only charging to 3.6V. compared to all of the original cells which charge to 4.15V.
When the battery was new all cells would charge to approximately 4.2v. giving me the 42v fully charged battery pack. As it should be for 36v battery.
Currently the whole pack charges to 39v. Then my charger light goes green. Asif all is fully charged. But the pack is made up of approx half new cells all 3.6v. and old cells 4.15.
Sorry I don't think I explain in the most simple way but I hope someone can understand and maybe help me.
