The Leaf:

I've watched 100s of videos and many things are crystal-clear:

• Hundreds of Video of Happy Owners that say nothing went wrong with their leaf in 10 years, except the battery capacity.
• Acceleration + Handling is Amazing
• Battery Capacity is measured in 12 "bars".
• Typical 2011-2015 Leafs are $9000-$15000, and have 6 to 10 bars.
• There are hundreds of owners in Victoria who love their Leafs, but want to recover their lost range.

Why Upgrade?:

• Even if I get one with 10 bars, within a few years it will drop to 6 or 7 bars

The Goal?:

The only older Nissan Leaf in town with all 12 of its bars for $7000
An Electric Car with 130km range. Or 220km with range Extender.
The Skills, Tools, and Ability to easily Upgrade my battery again in 5 years.
Possibly a business upgrading other Leaf Batteries.

18650 + 21700s Battery Trunk Packs:

Battery Calculator
Just an idea I've been thinking about for a while.
Would people buy them?
What do you think?
BONUS! There is Cooled Radiator Fluid already in my trunk!

• Most Leaf drivers *love* their cars, but *fear* their range loss over time.
• Nissan refuses to make new modules available at a reasonable cost.
• 18650s & 21700s are easy to obtain and build into modules.
• The used-module market is low in stock and risky.
• In Trunk Packs, each cell could be pulled out, individually tested, balanced, and replaced every 5-10 years
• *Passive* aluminum heatsinks, or *Active* cooling tubes could be added.
• I just came up with these rough cost estimates, not a real product.

Each 18650s3.2Ah 3.7Volts 12.5Wh 1C 2.85A, 45grams, $3.15
