Cool. I haven't had to actually make any yet, but someday, I'll have a box full of the molex connectors.

The SEC batteries last longer than the PRI, since the PRI fires the solenoid. When the PRI batteries get down to around 6v, I swap them to the SEC and bring the SEC up to the PRI. This seems to maximize the life, as a 6v SEC will work for quite some time.
There are some alternative battery mods as well for the Meg. There is a whole thread on that in here as well, so I won't get into it.
