Hi,
I have a 48V 50A LiFePO4 battery in the shed. I've topped it up every couple of months, and would like to knows it health. I'm thinking of testing its capacity using a 180W load.
Battery testing is very new to me so I do apologise for my silly questions.
Since it's only a 180W load, I imagine that I can only discharge the battery at 3.75A. That is is very different to the 40A that the battery would need to supply to a 2000W motor.
1) If the battery were to achieve 45AH on the 180W load, can I expect the same capacity when using it on a 2000W ebike?
2) Would the 2000W ebike cut off sooner because of voltage sag for example?
3) Is the battery capacity the only measure of health that matters, or should I test something else as well?
Thank you,
Fidel
