Good morning!
We have a Dinotte 200AA, with the standard battery holder and 9-volt battery connectors.

I'm thinking about trying something different, maybe using Trailtech connectors or what have you. What I really want to hear about is optional battery packs. I don't know the voltage range for the Dinotte circuitry, nor if there's a maximum limit to current.

The Dinotte 200AA's run on roughly 5 volts (four 1.25 volt NiMH's in series). Has anyone wired several 4-packs of batteries in parallel to increase the current? Is there a limit to how many 4-cell packs you could run in parallel?

Thanks!
