Mamma said there would be days..... urgh..
So local customer left an eZee 48v 10ah pack drain down by accident ( unsure of how it happened, but 10 of the 13 groups were at 3.2v and the other three groups were at 0v... tried to jolt the 0v groups back to life but they just get hot and drop voltage as soon as charge is removed..... dead.. )
So, since it's out of warranty ( would not be covered anyways... not a defect issue ) may as well try to salvage it.
My water bottle packs use the same Sony V3 ( 2200mah ) cells, and i happen to have one with a damaged BMS, so today's job... take 3 groups of 4P cells.. make them 5P, then cram it into the original eZee box !
fun times !
