Default Cheaper Lithium batteries

My friend at work found these nice looking LiFePO4 batteries that could serve as starter batteries.
They are much much cheaper than the 30Ah battery I bought around 3 years ago and paid for around £850.
The 30Ah models from this company are only $280.

The tricky part is going to be how to import them, is there a ban on shipping lithium batteries?

Either way, my main concern would probably be, how safe are these to use?

yes I didn't spot that, could be that they may not have high enough discharge rating.
Continuous is 30A, but it doesn't say the peak rating.

Found another one with a high discharge rating but it does not have a battery management circuit so that's no good.

Deep Cycle batteries will supply their rated output continously for an extended period over a starter battery and will be generally rated lower for a similar size/capacity as a result.
For lead acid it has to do with their construction.
For Li type I'm not sure how/if they control output, I would think they were slow(er) discharge by design.

Provided the rated output from these batteries is adequate (you need at least 300 amps, preferably 500-600), you can easily start a car with them (I've got a couple of those LiPo mini jump start packs for emergencies - they work great even with only having about 200 cranking amps (despite claims)).

My only concern would be accepting charge from the alternator - they pump quite a wallop energywise...
