Don't want to start a debate, but there are a few more advantages worth mentioning
. No need for an LVC or balancer
. Shorter Constant Voltage phase while recharging
. Will last a few hundred cycles longer
. Easier to reconfigure/assembling
. More secure: No fires, explosions, puffing ...
. I'm not worried when i subject A123 cells to water/snow
and so on ... simply fool proof

Of course lipos will remain unmatched when it comes to performance/wheight ratio.
And now, the disadvantages:

- Relatively heavy, especially in 2P mode.

- Resulting pack can be large and difficult to fit into typical battery trays, depending on vehicle.

- Really needs to be in 2P mode for decent runtime and constant current output. You could get by with 1P if in a light vehicle and/or run HV instead to reduce current.
