This battery was built by Bara from ChiBatteries about 2 years ago. Has had probably around 1,000-1,500 miles on it. It’s a 12s4p 40T battery. It was made for a Kaly ABS enclosure (the one that cracks easily).
Reason it’s free is because it’s not balanced and I don’t have the skills to figure out why. Some P groups are 3.45, some are 3.8, some are 3.91…
Anything besides local pick up should be a no go. Shipping a knowingly faulty battery isn’t something you should consider at any point.
Just my humble opinion thou…
