I’ve been preoccupied working for a few days.
I took apart a 48 module Leaf battery pack once outside in the wet mud. I knew it was hazardous but I didn’t know just how extremely hazardous. 300+ volts DC! There’s a reason they are sealed up tight in a heated metal case. A lot of 10mm bolts to get it apart.
Some friends into custom EVs bought several Leafs that were damaged during shipping.
Anyhow my 48 volt packs are 14”tallx14”longx9.5”wide. Each pack weighs about 40lbs. There are 7 modules in each of these packs. There are 48 modules in a full Leaf Pack so thats 14”tallx96”longx9.5” wide. Fairly compact.
To create one enormously powerful 48 volt battery from an entire 48 module Leaf pack all that’s required is to purchase one extra module from Green Tech Direct or other EV wrecker for around $80. And then reconfigure it into a giant 48 volt battery with creative use of numerous busbars. If memory serves it’s somewhere around 26KW energy storage total for a new standard Leaf pack. And supposedly around 80% capacity in a used pack, so around 20KW . There’s a vlogger who documented his motorcoach build he did for his family including this type of 49 module pack. I have 21 modules so less than half a Leaf pack but still a very big solar storage potential especially for mobile use.
