Hi,
SoS:
...but there is clearly an attempt to separate the cells.
A failed attempt that ultimately grounded a Dream...
The short circuit of cell # 3 (ANA TAK) was directly related of (improper) SEPARATION of the cells to battery case. I posted the equivalent circuit of this short that ultimately destroyed (fused) the ground green wire connecting the battery case to system ground.
Bear:
Mother Nature? I don't think so.
The short circuit was immediate! ("light speed"
The temp monitoring was useless since then...
Mother nature action was INSTANTANEOUS. Certainly more than 1,000 Amperes from the cell # 3 plus terminal to ground. (A mili ohms load to the 12 Volts of Yuasa LVP 65 three cells)
