update: sold.

I have an Opel Ampera battery where I have no direct use for, so if someone needs one...label says 16kWh

complete battery: €1700,- (plus tax if applicable)

per module:
4kWh module = €500
5kWh module = €600
7kWh module = €800

modules are easy to break up to 2 / 1 kWh parts.

What's the nominal voltage of the modules?

What's the nominal voltage of the modules?

it's built up from 6s and 12s modules, so roughly 24 volt and 48 volt

What's the nominal voltage of the modules?

The nominal cell voltage is 3.75 (not 4.0), so they are 22.5 V and 45 V.

The Opel Ampera is called the Chevrolet Volt in North America, and this document from GM covers both generations of the battery:
2016 Chevrolet Volt Battery System
The 2015 Ampera battery is the Gen 1 design.
