Hello! im new here! I mounted my cycle to become a e-bike with this battery and one bafang mid-drive 250W. 3 years ago. Now I am interested to know how much capacity the battery lost in three years lifespan. Is it appropriate to use 2 multimeters and 2 resistors 100 ohm 50 W for that? And how to connect the elements? Thanks for your help! barbegame
