Cheap would be to DIY.   I've got a thread in the build log section now and there's a group buy for cells happening.  Otherwise JY and Limitless seem to be the popular LiFePO4 cells tailor made. 

Otherwise I think the Sam's Club Duracell AGM is still the cheapest lead option and none of the "audio" branded batteries have changed much in the last decade apart from Optima quality going downhill.
