BMS and cell balancer assembly for Chevy Volt 36/48vdc 12 cell battery

Description

I am selling a PAIR of Chevy Volt BMS/balancer assemblies for 48vdc 12 cell Volt batteries as adapted for use in golf carts etc.  I'm selling the pair because the terminals were cut off one of them by the original eBay seller -- the extra terminals weren't needed or wanted in a two-battery setup like mine.
So I'm selling this
pair
well below other sellers' prices for
one
.
This pair came from a Club Car golf cart I was going to set up with two Chevy Volt Li-ion batteries, but decided to switch to LiPO4.
Note that
the eBay seller I bought it from assured me that
the unit is designed for both 36V and 48V Li-ion batteries -- he specifies it for the 48V Chevy Volt Li-Ion batteries he sells on eBay.
The charge control unit unit features a wire that connects to charger negative to provide a shutoff when the battery is fully charged at 4.2v per cell. This will allow the use of chargers that may charge over the allowed 50.4vdc limit.
This BMS does not control the input or output of the battery, thus restricting current like on LiP04 batteries. When charging a Lithium battery it is
critical
that the final charging voltage be observed to avoid damaging the battery.  Also, the user
must
provide an additional  device to protect the over discharging of the battery which would also result in damage.
To install just plug the orange plugs into the battery receptacles, connect the blue negative lead with eye ring to battery negative post and the BMS charger negative black wire to the charger negative.
Please feel free to ask me any questions, but I am not technical and have only the most rudimentary knowledge of electricity and electronics.
