Bose 4 wires battery

[eduaqa]

I'm wondering if anybody has more information about Bose 3.7v 4 wires battery.
What I know
the wires are red (+), black (-), green (Th), white (En) ... or green and white are the up side down, don't recall
As far I know, when the system goes to ship mode, the battery cut the power (- & +), and then to rearm you need plug on the power what generated 1.6v on the enable PIn and "turn on" the battery (- & +) wire
I'm wondering if someone has more information on that
Also if someone has any diagram schematic of that
