I don't really understand your choice of using the Headway cells to replace the stock 12 volt battery. 1.) They are very expensive, 2.) They were designed for very high rates of discharge (up to 10C, even 15C for short bursts) which the car's 12 volt battery will never experience, and most importantly, 3.) The cars DC to DC converter was designed to recharge a standard automotove battery and not a LiFePO4 battery, so I really wonder how long your new battery is going to last - It needs a regulator to shut off the charge at a very specific voltage
If you felt the need to change out the cars 32 Ah wet cell...
I know exactly what you mean. The LiFEPO is very expensive, but it has got a very good performance! The shut off voltage per cell is 3.65Volts, 4pcsx3.65V= 14.6V
The controller charge with 70A and 14.2V!
All electric power(12V&330V) you'll take with you is an big advantage.
For 2 times I run my traction battery flat, the car standing in a forest and hazard lights are flashing nearly the whole night!
If the "Battery-Turtle" comes, all 330V systems without the motor shut down.
You'll have only the 12V system, lamps, seat heating, fan, wiper.....
So, it's not a must-have, it's only an idea what's possible!
