Battery pack is cheaper, lighter and easier to swap between bikes.
The benefits of the dynamo are all mental. "Not having to think about power." etc unless you are really out in the wilderness with multiple days away from power supplies.
You can cheap out on dynamo wheels if you have rim brakes or if you build your own wheels.

pick one bike to do these rides on.
get a second hand SON hub or full wheel off eBay.
get second hand lights off eBay.
have fun. -
Use a Jtek hub!

I don't do audax (yet) so this is for my commuter bike. No forgetting to charge lights. No lights losing power halfway home, ...
Bike24 do some wheels with sp hub's. paid 145 euro's for mine but it was disc brake. Worth checking out as the sp hub's are already 100 euro's?

I paid £40 for a centrelock shimano hub, £9 for a 650b rim off px, less than a tenner for spokes and lights were ~£35 posted. Doesnt have to be super expensive

It’s unpopular to think of other people in 2020, but another benefit of a dynamo setup is that the vast majority (and all the decent) lights are dipped beam.
Not only does that not blind fellow people, but it makes a mad difference on visibility. When I go back to battery lights on my SSCX I can hardly see where I’m going now.

trying to justify getting a dynamo wheel built up, but struggling with the cost of it all. i've done multiple tours, audaxes and one pbp with battery power (on the latter i carried 3 power packs, about 35,000mah of power), and i managed fine, though it was an almighty faff at times.
i have a couple of bikes i use on rides where a dynamo would be useful, one is QR, the other 100mm thru axle; both disc brakes. the QR bike is the one i'd probably use the most, and i've had a quote of ~£200 to have a wheel built up which would be almost identical to the specs of the rear wheel. that's with an sp pv-8 hub, i imagine if i'd want it to be swappable onto both bikes i'm looking at the more expensive pd-8x hub? then, what, £70 for a decent front light, and £72 for an igaro? and i'd still need a power pack anyway for emergencies, and battery lights for the same.
spendy, innit. someone please tell me how easy your life became on night rides / really bloody long rides to make my mind up.
