buy the cells on eBay or Alibaba/express, 60-100ah 4.2v cells can be had for $40-120 ea, if your rectifier / power supply has a LVD that can be adjusted and a adjustable output voltage you just need something to do cell balancing, otherwise you can get a BMS that has LVD and a balancer inline, watch some youtube videos, the life cells are pretty popular with solar guys, etc and the $/kwh is equal or cheaper than your proposed lead batteries, and will last forever basically..
