Day 1

after a few years of research I have begun to build an electric vehicle and after two years(saturday mornings ) of rust removal I am still no closer to starting so the decision was made to get a ute for now and carry on doing the rust on the J 1 Bedford. so here we go!

the batteries

I had taken a long time to get them because I wanted to get a firm "Yes" in my head 

the choose was lead acid deep cycle batteries 

24 x 6v (220ah) batteries with a 2 year life high internal resistance (as the power goes through each battery some power is lost as heat so i will lose some of the capacity with lead acid it about 50% )

and to top it off they weigh 720kg 

so 24x6v= 144v(220ah/2=110ah) 144x110=15.84kWh  $6000 nzd every 2 years

OR

lithium 47x3.2v(90ah Only went this low to lower the cost)=150v lithium has a very low internal resistance (good)

it also has less weight only 141kg 

so 47x3.2v=150x90=13.5kWh  $8500 with a 10 to 12 year life and the are 579 kgs lighter !
