Main advantage of lithium-ion over lead acid is lithium-ion is more energy dense so you can have a smaller size at a smaller weight. Important if you're building cars, but the price premium probably isn't worth it if you're building another office box at commodity pricing.
Edit: Since we're armchair-building for a predictable, high-uptime application, failure modes might have an interesting advantage though. Any battery engineers know if lithium ion has more predictable or measurable failure modes? Yes, we've all seen the exploding hoverboards... I'm assuming theoretically well-built electronics.

The small size could be leveraged further by only attempting to provide power for a short amount of time, say 10 minutes, emphasizing and requiring USB connectivity to shutdown the protected computer at minute 9.
- thescriptkiddie 6y agoLithium batteries have a much longer lifespan than lead acid, which would eliminate the need to replace UPS batteries every few years. They are also more power dense, so if the goal is just to keep a machine running long enough for a clean shutdown, you can get away with a smaller (energy and size) battery for the same load.
