I was able to jump the car and by the time I got to work (~20 minutes) the trickle charging through the 0.3ohm resistor filled the lithium battery up to 12v. It's very early to say for sure but I'm leaning toward "don't buy this if your car ever sits below freezing" with regards to the lithium. The caps I'd still heartily recommend. Maybe even some smaller ones if you plan to use a very small conventional lead acid in parallel.
