Deep cycle batteries are a type of lead-acid battery. The Leaf uses lithium-ion batteries, which behave very differently. Still, lithium-ion batteries should never be fully discharged, which may be a risk with his modifications.
Any program that measures charge is making a educated guess based on the past behavior of the battery. One of the people interviewed for the article states: “Until you can find out how much is really left in the batteries toward the end of its range, it’s just a guess-o-meter.” Any indicator of charge is making a guess. Perhaps his program is better at guessing, or maybe he just leaves less room for battery health, but any program that works to tell lithium-ion battery charge will have to take into account the discharge profile of that battery (which is non-linear when measured by voltage).
