Hiya, heard about the forum from the Kweld NA Facebook group. Doc3G because I'm a medical student (and hence, will one day be a doctor if I don't blow myself up with lithium batteries first) and 3G for the 3rd Generation 4runner, the greatest SUV of all time. I started tinkering with electrons when I began designing an enhanced electrical system to carry the load for my off-road lights. Somewhere along the way, I got sidetracked into DIY lithium batteries and now have the goal to build a 48v pack for my golf cart that currently has 6 lead-acid batteries. If I survive that endeavor, my next goal will be to add some solar to the house and a powerwall.
