This Video series shows step by step on how to build a Homemade DIY Off grid Solar Powered PowerWall Backup System using salvaged and used Chevy Car Batteries.Here we are modifying an 18kwh (Gen 2) battery from an Old Chevy Volt EV hybrid, so that I can use the cells in a DIY Powerwall. The original battery is all wired in series for 355 volts. I'm breaking it down into 8 smaller batteries, each with 44 volts.This DIY Powerwall is using Chevy Volt (Gen 2) batteries instead of the usual Tesla or 18650 cells. This set-up will provide me off-grid backup power in case of an emergency.It's great that we can re-use and recycle these used car batteries.
