5Ah, and a 70C (-->350A) 10 second burst rating, and only 32 bucks. For a bigger engine, just use two.  I guess I'll have to buy quickly before you guys buy 'em all. |
Not sure that would be a good fit for 12v vehicle battery replacement. The reason people choose LiFePO4 despite the lower energy density is that a 4s configuration very closely matches the voltage of the lead-acid battery and alternator output of a vehicle. Not only that, but it's more tolerant of the non-managed charge/discharge cycles that the battery would be exposed to.
You would probably need to build a charge circuit to run the battery you listed, and it might be damaged by the low voltage since it wants to be at 15v.
