Battery from Buick LaCross hybrid 2014.
Advanced 0.5 kWh 115 V lithium-ion battery, air cooled. The complete battery has a 3 phase inverter. So it changes 115 VDC to 3 phase to run a 15 hp motor for power assistance. There are 2 battery units (cells) in one hybrid battery. Each unit is around 55 volts (measured).
This is the 5th hybrid battery I have removed from “junked” cars. It is nice and compact and much easier to remove from the car. The whole unit is around 65 lbs.
More info is on each picture. Might be very nice for a 48 volt solar system or a higher voltage robotic platform.
