I've used 1 nNovia device and it suits my purposes very well, except for the run time. The battery never lasts long enough. I can't fill half the drive before the battery poops out.

I really know little about how to do this, but I'm wondering if a motorcycle battery would give me longer times, (I imagine it would), and where could I learn the info I need to connect the 2 without damaging/ruining the drive?
I'm decently handy, but know little about power, i.e. amperage, voltage, etc.

Any suggestions?

A 12V motorcycle battery would certainly work, but could be a bit messy. And motorcycle batteries are better at delivering high current for a short time rather than small current for a long time. You may kill the battery if you deep discharge it.

Maybe a sealed lead acid battery? They are used in burglar alarms, UPS's etc and can normally cope with a deeper discharge at low current.

Personally I use a NiMH NP-25 (Part no. VSN031) battery pack rated at 3.0Ah . See ebay for various suppliers.

You always need 12V for the nNovia, but bigger capacity (amp-hours Ah) means longer run time.

The NiMH batteries are a bit smaller and lighter than lead-acid too.

HTH.

Thanks, Bruce. At least I have more to go on than I did before.
