GEO 2.0

Over the past few months I made many changes to the car.

I removed and sold the 24 Hipower cells.
I bought and installed 25 Calb cells under the hood in the front with a MiniBMS battery management system.
The car is driving well, no problem keeping up with traffic on the highway.

Here is the emergence disconnect I installed made from an Anderson disconnect:


Here is the racking for the cells before installation
