I can certainly see the headway cells would be much easier to put in the car.   They seem to be the normal Lifepo chemistry in a different package? I was watching a vid a while back about battery chemistry's and energy density's. Very enlightening. They were comparing the energy density of liquid fuels to that of energy density of batteries.  The upshot was when you build a battery getting near the energy density of liquid fuels, you have in fact built an explosive. Going to take a LOT to get batteries near liquid fuels yet and a long way off if even possible. No, I think the tools you have and the things you can do with them are just fine. Tractors are fitting by nature for the plebs like me with no skills what so ever.   They do however make it easier to load our embarrassing stuff ups into the ute to take to the scrapper's . My target capacity really depends on the weight of the chosen cells. I really only have about 100kg to play with. So that roughly equates to about 10-14kwh....Not massive but it isn't the type of car you would take on a long road trip. Yes Headway are just a different packaging of the same chemistry. Yes there is a lot of talk about increasing capacity. But I think the better direction is to make batteries easier to charge in a short timeframe. Charging more frequently (say every 500km or so) would generally be acceptable if it could be done in a few minutes.
