Do you have any software running that is looking for low battery ?

I believe APT gives a warning (or does something) on low camera battery.  Not sure if it's camera specific but most features can be turned off.

Catch-22

The low battery happens during slews.  When it happens the Camera can't communicate.  So the software just sees a comms failure.

You could possibly solve spikes on the lines with some capacitors to act as filters.

You reckon voltage spikes could be part of the problem?

It is certainly a possibility. In most electronic circuits that have communication sections unfiltered power sources can wreak havoc and cause constant comms. issues.

You could place an inducter in series with the supply and a decoupling capacitor across it to smooth it out. Another option is to run the 12v through a fixed voltage regulator (DC-DC converter). Most DC-DC converters have other circuitry to filter out noise too. However, getting one for the ampage you require would not be cheap.

If it was me, I would ditch the battery and get a properly regulated power supply.

Such as: http://www.rapidonline.com/Electrical-Power/Rapid-4A-13-8V-Fixed-Output-DC-Regulated-Power-Supply-Linear-Mode-77155

Another option is an ATX PSU from a desktop PC which also has 5v and 3.3v outputs. They have plenty of amps and as they are designed to power a sensitive PC motherboard are well filtered too. They are also cheap.

This shows you how to modify one nicely:

This Capacitor should solve any load problems!
