Can I use the built in battery in the C9.25 Evo to power my dew ring and eyepiece dew heater via the controller?

I've ordered a Celestron dew ring for the 9.25 and I'm guessing I'll also need to order a controller for it. But as for powering it, is it possible to plug the controller into the base of my C9.25 Evo and use the battery that's already in the drive? Of do I need to purchase some sort of 12V battery?

Best to use an external 12v battery as the EVO internal battery is really intended for the mount itself and is the wrong voltage. Celestron quote it as being 9 6 Volts which I read as 9.6volts (they missed the period).

Some people use camping batteries but then graduate up to the admittedly expensive Jackery batteries or similar. I use a Jackery 500 for my portable rig.

 

You will need a controller for the dew straps.

Thank you, TerryMcK for that input. Looks like I can't avoid purchasing a 12V power source of some description, in addition to the controller. Thanks again!
