The batteries

i have found that the blog is done last to first i had been putting the the time around so it read like a book first to last and have desided to leave it alone so hence the change. I was trying to think about the layout of the batteries the pack will be about 900mm x 1400mm so do i put the pack 900 across the deck or 1400 across the deck
900 seems the best option it will keep the weight close to the trucks center less sway going around corners. and later i will up grade the batteries to lithium not lead acid
