LFP is much safer than the other LI chemistries commonly used.
Fine for power density.
But energy density will be half or less, will get much greater range out of the latter.
There are many threads discussing various cells, IRL tests by members etc.
Most here use packs built up from lots of small cylindricals.
Looks to me you may have room for the pouche type, might give greater total Ah for higher total power and range.
