I built mine last night, and was absolutely thrilled that it worked first time, ready to go. Amazing, and a huge shout out to the team that did this - and props to Ian Fallon for a great job on the manual.
I have an Anker 10400 power pack and it's a great solution, and I'm happy with it. That said, it's in a shared Permit To Fly aircraft, and in an ideal world, I would either install it permanently with a feed through a step-down regulator, as previously put on here (which of course is fine, and one way to do it, but is a lot of faff), or alternatively to leave the PA unit in the aircraft and then get group members to bring their own battery pack.
Now that in itself I guess is fine - there's only four of us, but I was just wondering whether it's possible to wire up some kind of unit that takes 'every day' batteries and if so what type, or whether that's a cack-handed bodge, and whether the Anker is the most elegant solution all round.
Any thoughts would be gratefully recieved!
