just my opinion…. but…

The “electronics” you need to cut the voltage down from 12V to 6V would have to be really robust, and able to withstand about (at least?) 200 amps of current during the start sequence.

Turning over an engine (whether the system is 6V or 12V) takes the same amount of power. The formula for power is P = I * V. So a 6 volt system takes twice the current (“I”) as a 12 volt system.

Your challenge is also slightly more difficult because vehicles are DC (Direct Current), so you can’t use a transformer to easily step the voltage down from 12V to 6V.

One suggestion might be to keep a 6V battery on a 6V charger, and jump it from that…

Another plan would be to jump it with 12V. It would stress your system more, but I’ll bet that starter motor would really crank! Just apply the 12V for the minimum amount of time!

Let us know what your future path is!
