[ausev] Iota converter

[Joseph Kroesche]

Hello, I have been lurking on this list for a long time.  I am currently planning a conversion on a mazda truck.  I was going to share my plans with this list when it is further along and solicit feedback.

Anyway this question about the DC-DC converter raised some questions in my mind about the best way to deal with the 12V system.  The "Safety First" page says you need a 12V aux battery regardless so I was thinking I would just use a 12V car battery for that and not need a DC-DC converter.  My thinking was that the aux battery would last as long as the traction battery and I would just recharge both at the same time.  Is this arrangement common or feasible?  Do you tend to discharge the aux battery too fast if there is no DC-DC?

Thanks in advance for any reply.

Regards,
Joe Kroesche
