but if you put 2 or more in series, you want a balancer as well so they don't fall out of line.

There are some vendors (for example, PowerSonic with their PSL-SC line) which design their LiFoPo4 batteries to be direct replacements for classic SLA batteries, even for high discharge applications such as UPS's, for both parallel and series applications. As with all else, do your own testing in your own lab.
