12S4P battery with Smart BMS made with Samsung 40T Cells, made by TinPi (community builder).
Price: Free (collection from London/Brixton only)
Battery has not been charged in 4 years, but has less than 20 cycles on. Cells are unbalanced, but ive been told that 40T can become unbalanced if not charged. A slow charge and then leaving them can result in cells becoming balanced again. I dont have a garage to safely charge it and test etc this so just want rid if it, so the item is free but collection from London area only (sw9 specificaly). Battery is in great condition otherwise, as you would expect from an item that was barely used. I can upload photos later, but item is free
couple of pics - managed to find an old screen-shot of the cells, but i wasnt able to connect to the BMS via blutetooth to check current status of cells - either no charge of battery or my crap phone is playing up (either could be the reason tbh)
