@leikec posted:I’m looking at doing my first locomotive set, a powered Atlas 3R F3a/unpowered F3b pair, using the Blunami running off battery power. There should be plenty of room between the two engines to fit everything, considering that the F3b is unpowered.
Any suggestions on an appropriately sized battery pack to allow a reasonable amount of run time before charging? Would a 4 cell 18650 pack work?
I still feel like I have a ton of learning to do regarding this, but I am so very appreciative of the wisdom and great advice gained from all of you! Thank you so much!

Jeff. I don't know what the Atlas configuration looks like, but I did MTH F7's and did not need the B unit for battery. Everything fit in the A unit. LiIon 14.8v 3000mah with a Smart Charger should work nicely in either of these configurations. Remember to ensure it has a protection circuit for over charge/discharge.
I like MTO batteries. XML's appear to work the same at a discount price. I have recently tried HJE batts and have no complaints there either.
