I'm looking to build a LiFePo4 battery pack but am unsure on what are real capacities. I see listing on Ali-express for 12.8ah 32700 cells and am unsure if this capacity is real. Of course with Li-ion's I know that the 900000mah batteries are fake but I heard LiFePo4 has a higher capacity per volume so thats really thrown me. I cannot find datasheets nor a more reputable place to buy cells in my region so sniffing out the scams on Ali-Express is my only option.

I am assuming 12.8Ah is a scam but what is the highest real capacity of 32700 LiFePo4 cells?

Who actually manufactures these LiFePo4 cells?

And is there anywhere in the Oceania area I can buy them reputably?

The battery is for a 4.8kW Stealth bomber :shock: (not mine) Hence why I am not just going with normal Li-ion (dont want to burn their crotch or shed down)

Any help or pointers would be much appreciated
 
LifePo4 cells have LESS capacity for any given cell size compared to Lipo. The best LiFePo4 are only 150 ish Wh/kg
So that 32700 will NOT be 12.8Ah capacity.....more like 4-5 Ah.
You should also need to know what discharge rates are for any cell you use
