Without knowing the magnitude of the voltage ripple, not really. What you want to do is use a large electrolytic capacitor to dampen the voltage just like the lead acid battery did. I have a couple 15,000uF caps handy that I would try if it were me, but I'd also dig around and find something in the 1,000-2,200uF range to see if that was enough. Also, make sure they are rated for about twice the highest voltage you expect them to see.

I have a pair of Mean Well 600W 15V power supplies that I have run flat out on the PL8 with no trouble whatsoever. I know nothing of the Iota supplies, but it looks to me like they may be fudging their datasheet numbers a bit as they claim to have 3 times less ripple and noise than my Mean Well. Unless of course it is due to the Mean Well SE-600-15 having 3 times better load regulation than the Iota DLS-55.
