Hi All,
I am having some issues charging my Ebike Battery. I built my first 48V pack using Sanyo 18650s in a 13s4P configuration. Spot welded up everything myself and installed a BMS. Currently the charger I have is outputting 54.7V however it comes up with a green light to say its finished charging but the battery is only reading 52.6V from the output terminals. Its on a Hai-Long Case.
I should mentioned I tested all batteries before installation and they were all within 0.01V of one another.
My first question is: How much battery percentage am I losing by it only charging to 52.6?
What could be the cause of the charger stopping at that voltage? BMS cutout?
